Re: [SlimDevices: Audiophiles] Any good mods for Transporter out there? Validated?
There is actually some rational information on this subject as well. See: http://www.dself.dsl.pipex.com/ampins/groundloops/grndloop.htm Figure 3. For equipment with an ungrounded chassis, one can measure the AC voltage from the chassis to safety ground. When I first thought about this, my impression was that reversing the mains plug would only reverse the polarity of the AC error signal and not affect its magnitude. But apparently this relationship does not always hold with real hardware. The only reason I can think of for this is some kind of asymmetrical load between positive and negative supplies of typical hardware, giving a partial cancellation of the residual AC signal in the preferred state. Because the residual signal is from an asymettry of the transformer, the optimum polarity will vary from unit to unit. Of course, audibility of this situation is debatable - yet I'm sure it will be trotted out by the usual suspects for some time to come. -- andy_c andy_c's Profile: http://forums.slimdevices.com/member.php?userid=3128 View this thread: http://forums.slimdevices.com/showthread.php?t=36626 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

The article suggests disconnecting the protective earth connection from your equipment to make measurements or to improve sound quality. DO NOT ATTEMPT TO DO THIS FOR ANY REASON. IF YOUR EQUIPMENT HAS AN EARTH CONNECTION IT'S BECAUSE IT'S REQUIRED FOR SAFE OPERATION. TOUCH THE UNEARTHED BOX, AND THE FIRST YOU'LL KNOW OF A FAULT SOMEWHERE IN YOUR SYSTEM COULD BE A FATAL ELECTRIC SHOCK. (After all, you wouldn't go round replacing all your fuses with nails to 'improve the power supply', would you? You would? Darwinian evolution in action. Go right ahead). But, suppose for a moment that you were actually dumb enough to make the measurement anyway, or that your equipment is designed such that the earth connection isn't needed. What are you actually measuring? With the case disconnected, either by double-insulation from the mains or because some idiot has removed the earth connection, it's essentially floating. Maybe it's connected to the analogue ground which is shared with the rest of your system, but not necessarily. It may also pick up a voltage by capacitive and/or electromagnetic coupling from the power supply, but in this case the impedance will be extremely high, and only a rather expensive meter will pick it up. So, what you're measuring is the potential between this undefined point, and earth at some other point. Meaningless - but audiophiles like to find something they can measure and then come up with a rule for what it should be. It's not impossible for reversing the live neutral to make a difference to the sound, though. In the UK at least (and presumably elsewhere), the neutral wire is kept around earth potential while the live oscillates either side of it. So, if inside your equipment there's a live wire nearer some sensitive audio signal than the neutral, there will be a greater degree of interference introduced. Swapping live neutral effectively moves the noise source further away, which can indeed help. You can't tell whether this is the case by making meaningless measurements of the voltage on the outside of the box, though. And the idea of trying to 'match' these voltages across components is just... well, rubbish too. So, if you have reversible mains plugs, by all means swap them around and pick whichever way you like the sound of. Just don't electrocute yourself by doing something silly, OK? ;-) -- AndyC_772 AndyC_772's Profile: http://forums.slimdevices.com/member.php?userid=10472 View this thread: http://forums.slimdevices.com/showthread.php?t=36626 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

One unfortunate difference: the AK4397 isn't able to accept a 3.3v digital supply, only 5.0v, though it does accept 3.3v logic input levels. So, any modification would have to provide a 5.0v supply, ideally separate from the analogue 5.0v, and would also have to disconnect the digital outputs (which I doubt are needed anyway). That's unless, of course, Transporter uses 5.0v to power the AK4396 digital side - anyone know? (Sean?

Ah - there's an international variation there. Here in the UK, as I'm sure you know, we have 3 pin plugs that have a fuse built into them on the live (hot) side, so it's quite hard to electrocute yourself. The only occasion on which it's normally possible to swap live neutral is on equipment that has a non-earthed 'figure 8' plug, as a lot of hi-fi kit does, and in those cases it's quite safe to plug it in either way round as the kit has to be double insulated anyway.

I agree that reversing the primary wires may reduce the residual AC voltage in some cases. -- andy_c andy_c's Profile: http://forums.slimdevices.com/member.php?userid=3128 View this thread: http://forums.slimdevices.com/showthread.php?t=36626 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

CPC;214097 Wrote: I've been told the best connection to the primary side is the one that yields the lowest voltage reading from neutral to ground/chassis. I think you'd want to measure from the local safety ground to the signal common (say, outer ring of RCA jack), assuming the equipment does not connect the chassis to safety ground. So this would only apply to Class II (double insulated) equipment. But the transporter AFAICT connects chassis to safety ground, so to make this measurement, you'd have to break this connection - probably not wise unless you're very familiar with safety issues. Neutral is not a good ground reference because, although it does eventually go back to the ground rod in the home, it carries the return currents of equipment and appliances plugged into that line. So it will have an AC voltage drop due its resistance from the point of measurement to the ground rod and the current flowing through it. Ideally, the safety ground wire will have no current flowing through it - unless there's a ground fault in a piece of equipment plugged in somewhere. So for class II equipment, this tweak is free - so why not? Just reverse the plug. I'd still like to see some system noise measurement that demonstrates that the tweak works though. There's so many audiophile old wives' tales floating around it's hard not to be skeptical. -- andy_c andy_c's Profile: http://forums.slimdevices.com/member.php?userid=3128 View this thread: http://forums.slimdevices.com/showthread.php?t=36626 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Its funny with glare and glassyness you can liv a whole life hearing it but its when its gone you hear it and when its gone you will never go back to stock or glarish frontends again. But i will still fullhartly recordment the transporter becaue there is one area besides the fantastic userfriendlynes where it really shines and that is when you plug it straigt into poweramps .

When designing complex PC boards, it's a good idea to put pads for series elements wherever feasible on power and IO lines. Then when you test the system for emissions, you may need to experiment with chokes, ferrite beads, resistors, and caps to identify and suppress specific sources RF. Often this process takes several weeks and many board spins, since you can't always just cut-and-jump the changes. That's why you need to put the pads in - you can't just wire these parts in by hand and expect them to perform the same way. When the board is ready for production, you don't go back and remove all the unused pads. There would be no benefit to doing that, and you actually would run a significant risk of changing the characteristics of those traces or otherwise introducing some new error. These extra pads are referred to as NP for not populated, but I'm sure you knew that. If you look at pretty much any circuit board you will see places for parts that are not there. That does not mean that the designer messed up. It means that the part could be installed (or not) for any number of reasons, not just EMI but also feature differentiation between products sharing the same PCB, configuration bits such as an IRQ or clock speed, alternate footprints for second-source parts, and so on. But again, I'm sure you design circuit boards all day long and you know all of this. So back to the case in point: in all likelihood, unless you actually tested your modifications it is quite possible that you have created an EMI problem where there was none before. But what do I know - I only DESIGNED it, right? So, now that I have answered your questions, would you kindly answer mine?

Sean, When I received my first Transporter, The first thing I done was plugged it in to my bench power bar. Without realizing, I had a noise sniffer plugged in the same power bar .. Do need I say more? I popped the cover of the transporter, and found to line filters was omitted from the design. Further investigating, I realized that the package size of the filter components was incapable of handling the amount of current the transporter required. So instead of redesigning the whole Pc board to accept properly sized filter parts, they was jumpered and shipped, as is. So if anyone is looking for a Validated Mod Install a HQ dual stage line filter in between the IEC and pc board. The one I use has world wide compliance built in to it. This can be the reason why your line filter was ommitted from final design. ;c) So your theory of I created is tossed out the window.. :c) Anthony -- aberdeencomponents aberdeencomponents's Profile: http://forums.slimdevices.com/member.php?userid=1234 View this thread: http://forums.slimdevices.com/showthread.php?t=36626 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Why not a linear PSU for all voltage rails? I did in fact test both of those ideas and there was no significant difference in EMI or any other kind of noise. That SMPS is simply not a source of noise to be concerned with, which is exactly why I chose it. The only difference you'd get by putting a linear supply in it's place would be that the system would weigh a couple more pounds and run a hell of a lot hotter. Probably hot enough to need a fan or some beefy fins on the side. The circuits which it powers are high-current things which are not sensitive to ripple, such as the display filaments, the magnetic braking mechanism in the knob, and the 1.2V supply for the CPU core. It also powers the auto-ranging circuitry which measures the incoming line voltage and configures the transformers properly for the linear supplies. For that purpose it's nice to have a PS which can comfortably handle a very wide range of input voltages. There are a lot of audio companies who do things just because, but that is not the way I engineer our products. -- seanadams seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=36626 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] Any good mods for Transporter out there? Validated?
well I say try it out for yourself. it's not a big deal... unplug everything and just try it with your CDP / AMP combo... don't expect the sound to change, but the stereo stage / image... I will kindly await your answer. -- truckfighters | Transporter | REDGUM RGASil OCC Silver Interconnects | REDGUM RGi120ENR AMP | REDGUM LS Cable | BW Nautilus 802 D | Live musicians at the end of my room! truckfighters's Profile: http://forums.slimdevices.com/member.php?userid=7852 View this thread: http://forums.slimdevices.com/showthread.php?t=36626 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

From the input transformer's perspective there simply is no polarity, and phase can only be defined in relation to another signal. Within your house wiring system you will have a neutral and a hot, and they need to be wired correctly for safety reasons and for proper functioning of multi-phase wiring. For example, a light bulb socket has neutral connected to the sleeve of the plug so that you're less likely to be shocked by touching it, but it would work just the same if you turned them around. Likewise, since the transformer primary is not connected to earth ground, in that context their voltages are only meaningful in relation to each other, so they're the same either way because a sine wave is symmetric. If you were to connect a voltmeter or floating scope to the leads it would not matter which way around you connected it, you would get the same thing. The system's earth ground is for safety and is not a return path for any input current, so phase of the power input is meaningless. -- seanadams seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=36626 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

I've never heard that one before. You might as well say that it matters at what exact moment you play a track as you need to make sure that the music is exactly aligned with the absolute phase of the mains supply. And logically 50Hz units will sound different to 60 Hz units. It's also potentially lethal if you start rewiring units to reverse live and neutral in case only live is disconnected at any mains switch. -- CardinalFang CardinalFang's Profile: http://forums.slimdevices.com/member.php?userid=962 View this thread: http://forums.slimdevices.com/showthread.php?t=36626 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] Any good mods for Transporter out there? Validated?
as far as I am informed it has something to do with several devices connected to each other via. e.g. RCA cable connection. you might get different potentials, if one device is connected out of phase and the other isn't. surely AC is AC and the whole sentence I wrote doesn't really make sense. but a lot of high-end manufacturers mark the hot phase on their audio devices. and there are quite a lot of phase-detectors out on the market. this is also used in the video domain. electrode voltage / potential difference / difference of potential are the correct words in english :) I am sorry, my english is to bad for the correct technical explantation. you might have devices where it is uncritical. but there are surely devices where you can hear a difference between the plug installment (180° turn). different resistance in cables/ connections generate different potentials in the devices and normally they balance through the earth. but if they don't they can crawl over your RCA connections and change your sound... just try it out - its for free! -- truckfighters | Transporter | REDGUM RGASil OCC Silver Interconnects | REDGUM RGi120ENR AMP | REDGUM LS Cable | BW Nautilus 802 D | Live musicians at the end of my room! truckfighters's Profile: http://forums.slimdevices.com/member.php?userid=7852 View this thread: http://forums.slimdevices.com/showthread.php?t=36626 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Any good mods for Transporter out there? Validated?
There is a phenomena connected to radiated RFI that can change according to which way round you connect live and neutral ON SOME EQUIPMENT. I have a device called an RF Sniffer that produces an audible signal when it detects RFI/EMI (bit like those things they sell in DIY shops to detect mains cables hidden in walls). SOME equipment gives lower emitted readings when connected one way round... Damned if I can hear a difference in sound though! -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal... ...SB3+TACT+Altmann+MF DACXV3/Linn tri-amped Aktiv 5.1 system and some very expensive cables ;o) Phil Leigh's Profile: http://forums.slimdevices.com/member.php?userid=85 View this thread: http://forums.slimdevices.com/showthread.php?t=36626 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

There are phase inversion switches on some gear for the audio output - nothing to do with mains supply. Some people believe that some recordings were made out of phase to others and by flicking the switch you can restore them to their correct absolute phase. It also might work in cases where other gear in the reproduction chain have reversed phase during amplification stages. In other words, you make the loudspeakers move in the same direction as the monitors in the studio. Given that recordings are made up of many tracks with all types of effects, compression and filtering on them, I doubt that this has any audible effect. Of course having one channel out of phase to the other is audible as it can cancel out pressure waves in the more monotonic signals at the low end. Personally, my ears are so shot by live concerts, I wouldn't claim to hear any perceptible differences! -- CardinalFang CardinalFang's Profile: http://forums.slimdevices.com/member.php?userid=962 View this thread: http://forums.slimdevices.com/showthread.php?t=36626 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] Any good mods for Transporter out there? Validated?
I recalled when i somtime ago contacted Lyngdorf audio and asked about getting my millennium mk3 moddified i also remember how many words lyngdorf audio used to try convincing me that this modder was the devil himself and all his work was absolutly useless , but what was most memerable was how the moddification absolutly embaresd the sound off the stock unit . I have never looked at the hifi industri the same way again. And im the guy who sold 20.000 worth off cables and powerconditioners because the made absolutly no improvment to my system only sligt differences. I have no idea if the analog part in the transporter can be made better because i have not heard it after it has been moddified . What i do know is that the aberden transporter sounds alot better as transport then the stock unit and it really is aparent form the first second off playing . but its the same thing that manufactors always say about people that makes there products better then them self ... ... ... could swap out a bunch of random parts for you, but that'll make it sound worse. All the mods for Transporter that I have heard of appear to be, IMHO, complete BS. One modder even claimed improvements after doing unspecified mods, before we had even shipped the first Transporter. I have not heard of any modder performing the sort of rigorous testing that I did on Transporter prior its release.

Re: [SlimDevices: Audiophiles] Any good mods for Transporter out there? Validated?
Harmonic, Perhaps you should try blind testing. I doubt you would hear a difference. As I have stated many times, NO difference was heard in the modded TP through several very high end systems by a group of very experienced audiophiles. But if you want to spend your money on questionable upgrades that is certainly your right. As to modders making better gear than the original designer I guess you would need to feel that way to justify your expenditure.
