[SlimDevices: Audiophiles] Changing your linear pwr supply for the Duet
I bought two of the (semi-famed) Power One HB5-3 power supplies. I use one for my Squeezebox 3 and was planning to use one for the Duet I had on order. OOOPPS!! The Duet needs 9 volt in, not 5. Hmmm... Anybody know how to change the HB5-3 to 9 volt? Just a matter of a resistor or two I am guessing, but anybody know which ones? I found the datasheet for the LM723N used in the Power One here: http://www.chipcatalog.com/ST/LM723N.htm The datasheet shows schematics for applications, and I'm guessing the schematic that applies to the HB5-3 is either schematic #16 or #17, but that's as far as my limited electronic neurons take me... -- atkinsonrr Transporter, Quicksilver V4 Monos, Vandersteen Model 5A speakers.

[SlimDevices: Audiophiles] Re: Personal Introductions: Please Make This a Sticky!
Hi, my name is Rob, and I'm an alcho er audiophile. I played trumpet for a long time, and for the past year or two have been dabbling in guitar, but I wouldnt call myself a musician. I got my start listening to LPs of Cream or Pink Floyd or Clapton, in a garage with a bunch of other high schoolers. Solder smoke mixed with other smoke, wafted along on air vibrated by the best stereo in town, thanks to my geeky best friend. He was always building some Heathkit thing or another. Later tended equipment and did the mix for a couple of minor recording bands. This got me fascinated with how an amp or PA might have a particular emotional impact and why. Thats what drives me in audio. I think of it as the intersection of the technological with the psychological. It lends itself to a sort of endless noble quest. Once I got out of college and grad school, I finally had enough money to buy a decent rig: Magnepan II's and Audio Research electronics. Since then I've owned alot of different things. In speakers: Klipsch Cornwalls, Quad 989s, Spendor monitors, Quad ESLs, Martin Logan Sequel IIs, Carver Amazings, a pair of small Maggies, Advent Large, JSE Infinite Slope, Mordaunt-Short monitors. My current main speakers are a pair of Vandersteen 5As. In electronics I have had a variety as well: Home-built Tripath Digitals, McIntosh both classic and new, Classe, EAR 859, various Audio Research, Conrad-Johnson. When I get back to Montana I will be rotating out McIntosh and putting in Quicksilver mono-blocks. Why am I now involved with Slim Devices? I think its the future. Once you use hard-drive based audio its hard not to think the days of discs are numbered. My philosophy in audio is probably a bit different. I have given up trying to find accuracy or fidelity to live music. I am just in it for the emotional high that a great system playing great music can bring. And over the years, I have come to the conclusion there are many ways to get there. In fact, I often have three systems set up. So when I get back to Montana, I plan on setting up a couple of other rigs in addition to the Vandersteen-Quicksilver system that will be fed via Transporter. Quad ESLs and a pair of ancient tube monos will be fed by an SB3 in the bedroom. In the office I plan on setting up Spendors with a Tripath digital amp fed from the computer via USB DAC. As for the objective-subjective debate. I can remember a time before Total Harmonic Distortion was used and before anyone had heard of this thing called jitter. So I dont think measurements via instruments are anywhere near close to comprehensively describing audio reality. Nor do I think ABX testing is the holy grail. Its my experience that it takes time to really hear and appreciate. I readily embrace the fact that there is a big psychological, perceptual component and I'm not sure how you control for all that without destroying what you are trying to measure. But, being schooled in the social sciences, I know there are ways to tease out objective measures for that which is wholistic and subjective. If and when that happens, we can all live in peace, as the subjective and the objective will have been reconciled. -- atkinsonrr Transporter, Quicksilver V4 Monos, Vandersteen Model 5A speakers.

[SlimDevices: Audiophiles] Re: Wanted to Buy: Modded PS for SB3
Thought I might just throw out a suggestion here. A while ago, I wanted to try a super duper tweako power supply on my CD Burner, just for grins. I was gonna build one, but then had a thought. Went to Ebay and found power supplies on sale that were surplussed from laboratories. I took a flyer and bought one. I think it cost me about $40 incl shipping. It arrived, very impressive, weighing about 25-30lbs, a nice meter, rack mountable, only a couple small dings. If I remember right, it had Bell Labs and a serial # scratched into the bottom plate. I never did an A-B but it worked great and I know I just felt a little better knowing it had this huge reserve headroom in terms of amperage draw. When I get back to Montana I hope to use it on my SB-3. If I remember I'll attempt an A-B test and let you all know. -- atkinsonrr Transporter, Quicksilver V4 Monos, Vandersteen Model 5A speakers.

If they didn't beat a device costing 1/5 as much (which includes a high-end DAC, mind you) they'd have some explaining to do. It's also all relative, of course. It's not like that reviewer's opinion is the last word on the Denon or the Transporter for that matter. In fact being compared favourably against a player costing nearly twice as much is a high compliment. I think Mark has it right. When this happens to me, I know most of my bad feelings are coming from the sinking realization that I got fooled by marketing hype. Maybe its less about the transporter and more about kicking yourself. I mean by any objective measure, the TP is still shaping up as a great purchase!

I really dont think this is a reasonable request. He's already said that he is doing it based on the track record of his own experience with the modded SB. So, one could say he is doing it out of trust in Boulder Mods. You might argue his trust is misplaced, but I would bet he believes his trust is justified by his own experience. Shouldnt his own experience be the final arbiter? At this point you might say that he was fooled by psycho-acoutic or simply psychological factors. In other words sometimes your own experience can lie. I agree with that. But if he's like most of us (incredibly intelligent!!) people who habit this forum, I again would bet that he did some kind of A-B testing. Is the A-B testing up to a standard that we would all accept? Maybe not. Its obvious you have real passion for finding the truth in audio. But, I dont think you are gonna persuade or change his mind by demanding that he provide all the justification you are demanding.

I agree with your following post, as well. Once you clarified you mean specific measurements when you say Transporter is unsurpassed. If someone is to claim you guilty of hype, then (given your clarification) they should show on what specific measurement and against what specific rival machine you have overstated your claim. I would hope that modders could show some empirical, instrumented, improvements. On the other hand, I wouldnt claim a modder is full of BS simply because all he could say is he performed listening tests and found his mods sounded better. I would take that as information, even if not very compelling information. It would be more compelling if he could substantiate it was done independently, with a variety of equipment, a variety of listeners, there was some control for bias, listening was done over an extended period of time, etc. Of course, most compelling would be if said modder could report results of empirical listening tests. Having a social and not physical science background I believe there is a way to make non-instrumented testing empirical as well.

The above quoted post is such a great example because the assumptions the poster is making about me are so clearly stated. But it happens all the time. For instance many people assumed that PFloding was putting them down by inferring they were not audiophiles. And so they attacked in defense. But in earlier conversation P said that English is not his first language, and admitted his ability to get grammer and spelling wrong. I thought it was plausible that P simply got the meaning of audiophile slightly wrong, and that he meant to say something like tweaker instead.

A while ago, P.Floding started a thread called something like Moderator where are you?. In it, he makes the following point: The biggest problem is the SNR (signal-noise ratio). It is really easy to do wisecracking and post the 50th variation on the same old joke and get a number of your buddies to chime in with their own variations. Soon you have 10 postings like that for every one serious posting. How is anyone going to take the time to read through all this to extract any useful information? On top of that, when all the wisecracking has a theme that says that audiophiles are idiots (more or less), how friendly will that feel for anyone coming here with their questions?

[SlimDevices: Audiophiles] Re: Good entry level speakers
Over the years I've made some mistakes I might help you avoid. Speakers more than any other component have a sound. Give up any notion of putting speakers on a universal scale from good to bad. Recent research suggests that different people process and therefore hear music in very different ways. This must be true, as some systems I have considered unlistenable have been adored by people whose judgement I respect. BTW this also means you should actively disregard the conclusion from any speaker review. You must find what you like. And for less then awful-big money you wont get it all in a speaker (if then), so you need to be honest about your priorities. For ME speakers line up along three axes. You might find the same helpful. Think about it: what aspect of the music really speaks to YOU. Is it the harmonic richness of a voice like Norah Jones' or Johnny Hartman's? Is it the feeling of being inside the music that you get when you put on a super well-recorded, well-produced track?. Is it the visceral impact of the Stones or Mahler? Once you are well grounded in your priorities, speaker reviews can be helpful if used to interpret if a speaker aligns with those. Narrow down your search by determining if a boxless planar design is for you. The three brands you will most likely run across are Magnepan, Martin Logan and Quad. Quad planars will be hard to later augment for surround, so you might rule them out. Planar speakers have a sound all their own, and if it really floats your boat, it is unlikely that anything else will do. If for reasons of sound or practicality these dont do it for you then you can move on. I have lived in places like Alaska, rural Scotland and Montana, so I empathize with the need to sometimes get a bit more direction than go listen. So here is where I will stick my neck out and give you brands to think about. For comparison sake, I will use $2K (new price) as a max budget. (If you are in the US, take the advice about Audiogon.com). They are well respected, excel at what they do, and are exemplary of the different poles, if you will, of priority in sound. There are certainly many more brands out there, but these I have either owned or been very familiar with. If nothing else, you might use these to anchor your search. Harmonic Richness: Vandersteen's Model 2 has been around forever. There is a reason. It does this rich harmonic thing so nicely. If looking at planars, Magnepan is voiced in this direction. Inside The Music: Spendor gives you the polite British version of this sound. Good models available under $2k. Detail and spatial cues galore. They are one of the origial makers of the iconic, inside-the-music LS3/5a. The more exciting and in-your-face American version of this sound is Thiel. In planars, the Quad ESL (but way beyond 2K new). Visceral Impact: The classic Klipsch speakers (Klipschorn, Cornwall) could be had used under $2K. I have heard their recent designs only in stores, but they seem to carry on this tradition. In planar speakers, Martin Logans. -- atkinsonrr atkinsonrr's Profile: http://forums.slimdevices.com/member.php?userid=7214 View this thread: http://forums.slimdevices.com/showthread.php?t=29736 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Others, like SuperQ, believe that properly-executed digital attenuation has no effect on sound quality. One of the ways cited to properly execute attenuation is to do it in 24 bits, which is how Transporter does it. SO we never got consensus.

I find the same true of forums like this. This got me wondering: What would happen if we efficiently harnessed the collective power of this forum to develop tweaks to Transporter? One way to characterize an efficient approach would be: 1. Idea Generation- a simple brainstorm list without censoring, or evaluation; no ownership of ideas; just get the ideas captured. 2. Cost/Benefit Analysis of Ideas- use the forum to discuss likely cost/benefit of each idea one at a time in order to screen the rough list. Then distil our judgement by some kind of structured valuing or voting. 3. Testing of Selected Ideas- assign willing testers to actually install the tweaks in their Transporters and test results using methodology this forum agrees on. Methodology can include both objective and subjective approaches. 4. Selection of Proven Ideas to Implement- final discussion of results and evaluation of which ideas are 'proven' and worth implementing. I can hear people screaming: GZ this things is barely out of the UPS van and you want to improve it? Why? My answer is: Cause thats what we do, we cant help it!

Evidently APL is using the same AKM4396 chip but using SIX of them per channel. This got me to remembering reading a few years ago about the possibility of improving DAC performance by piggybacking the D to A chips -- actually placing an identical D to A chip above the one already on the board and simply soldering its corresponding leads to the one below. Hmm Not that I am ready to do this to my Transporter right out of the box. And, I am not making any assumptions that this is the way APL is implementing its multiple chips per channel.

[SlimDevices: Audiophiles] How Best To Attenuate Balanced Outs?
Hi-- I have a Transporter on the way and will be using the balanced analog outputs into balanced inputs on my amps. They will be connected via 2 meters of balanced cable. If I understand correctly, due to use of a digital volume control, theoretically the best sound would come from having that volume control turned up all the way. The reason being that (although some argue that the affect is negligible) the digital volume control operates by throwing away bits, and with those bits, some resolution. I'm guessing that's one reason for the attenuation offered on the rca/non-balanced outputs. Assuming the above is true, I would like to find the best way to attenuate the balanced signal so the volume control would be at 3 or 4 O'clock for normal listening. What is the best way to implement this? And would it best be done inside the Transporter chassis, before the interconnects or inside the amp chassis and after the interconnects? -- atkinsonrr atkinsonrr's Profile: http://forums.slimdevices.com/member.php?userid=7214 View this thread: http://forums.slimdevices.com/showthread.php?t=27616 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

And, in doing so, will it be dynamic sounding like a regular preamp or will it sound more constricted like a passive preamp (in my experience, they tend to sound less dymamic or lively)?

BTW I am NOT a techie so pls be gentle with me -- atkinsonrr atkinsonrr's Profile: http://forums.slimdevices.com/member.php?userid=7214 View this thread: http://forums.slimdevices.com/showthread.php?t=27158 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
