A tube in free air is always going to pick up vibrations through the pressure waves, even if it doesn't get the ones from the furniture it's sitting on. Let's face it, you can feel the bass in a good system, so how on earth do you stop that shaking the tubes and components in the stereo with some isolating platform? I also accept that the sense behind some of this is the tiny movements of wires due to vibrations, especially in point to point wiring. If there's any sort of magnetic field around, then currents will be induced by the vibrations too. If these wires are inside the boxes of the amp and therefore shielded from the sound pressure waves to large extent, then isolation should help there.

Hi there, Can anyone advise me where is the best place to buy a cheap and safe power supply upgrade for the SB3. I've read all the reviews in how it improves the sound and I'm interested. All I know is something like it has to be regulated 5 volts at 1.5 amps. I don't want to have to do any extra soldering, and definitely don't want to damage my new SB3. Straight out of the box would be nice, especially if can be bought reasonably cheap. I'm quite new to all this and I'm UK based, so go easy on me.

[SlimDevices: Audiophiles] Re: Any one know anything about the little isolator blocks you put under the feet of cdp?
My personal experience is that certain isolators have worked incredibly well with turntables, and noticeably improved tube amps/preamps and some CD players. Of the various ones I have tried (those that absorb and release, those that insulate), my favorite products are the Final Labs Daruma, which use a steel or ceramic ball b/t two cups. Haven't tried but heard good things about using a heavy base supported by racquet balls or tennis balls cut in half. I get why these devices would work in a turntable, where vibrations transmitted to the pickup device would be thereafter amplified downstream. I also get why they work in tube devices: tubes are microphonic and could amplify noise/vibration. Could the same be true with non-tube DC players? Why not? After all, these devices have amplification stages which are not immune to the effects of vibration. Scientific studies have demonstrated that vibrations can be amplified and interfere with and obscure the original amplified signal. Check out the following articles: http://www.rtd.com/images/movie/IDAN_VIB.PDF I have my SB3 sitting on an old pair of Audioquest sorbothane feet, but can't say I notice any differences. My computer is not sitting on any feet, but does sit on an older target rack with spiked feet.

If you really want extreme vibration protection, just build something like I did in grad school. I needed to do very sensitive microindentation experiments, where accuracy down to 1 micron was necessary. As you can see the whole setup is on a large (200 lb) steel plate, which is suspended by bunjee cords on a steel frame. The tennis balls are not touching the plate, they are just there for an emergency! This kind of vibration isolation platform is cheap and provides just about the best isolation there is. I should know, because we had vibration tables, and they didn't work for us.

I've heard all sorts of claims that devices are microphonic, from the more obvious tubed amps to less obvious PSU capacitors. If any of it had an impact a true audiophile would have all his gear except the speakers in another soundproofed room. But then again they wouldn't be able to admire the wooden feng shui blocks under their solid state amp. I can't see how an SB would have any form of microphony at all though, but the old SB had a slightly rubbery feel to it, so perhaps the case was slightly more absorbing of sound than the new SB3 case.

Not instigating, just > curious : ) Not sure about microvibrations, but lots of tubes used in amps and guitar amps tend to get microphonic as they start to fail. You can turn the amp on, bang gently on the chassis and hear noise from your speakers. You know that feedback from the speakers has to impact the sound thru the tubes. Supposedly, good, new, tubes are not microphonic. But I'm not so sure. The way they work is putting charge on a grid, which controls the flow of voltage. Moving the grid has to change the voltage, and thus the sound. Not sure if it is engineering or just marketing, but a lot of audiophile tube amps weigh a ton. 90 pounds of amp isn't going to move much, unless you have the gain turned up to 11. -- Pat http://www.pfarrell.com/music/slimserver/slimsoftware.html ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

[SlimDevices: Audiophiles] Power supply upgrade
Audiophile forum, Thanks for the tip to upgrade power supply from stock. I knew something wasn't quite right with SQB since it didn't really pop as everyone here said it should. So I swapped in a 16 watt linear PS that I had lying around. I can't believe the difference. I am playing wavs, ripped from CD using EAC. The dynamics, clarity, timing, everything is literally doubled in improvement with the bigger PS. It is simultaneously more delicate and refined while having much bigger and ballsier power in mid and bass. It is not subtle at all. You don't need golden ears to hear the difference and it is so cheap to upgrade. The SQB3 plus a good PS upgrade has superior performance to $1000+ dedicated CD players. I have not listened to players that cost more than that, but it is better than any at dealers that I have tested at home with my system before buying SQB. I am so happy with my decision to buy SQB instead of stand alone CDP. Anyone interested in getting the best sound from their system should upgrade the SQB power supply before you make any other tweeks to your system. Mine is a full blown stand alone powersupply with a large tranny, and large caps and regulation circuitry that hold it at 5V no matter the load, up to a full 2amps continuous. This is what accurate dynamics require - CURRENT. It even has remote sense to monitor voltage at the device, but I have not used that. Thanks again!

It made a lot of sense back in the days of yore with turntables. It makes far less sense with a CP player, but audiophiles are not the most rational people.

[SlimDevices: Audiophiles] Re: Hosfelt Power Supply
Horizons I just soldered a connector to my new power supply (see separate thread) this morning. I used Switchcraft part #760. http://www.switchcraft.com/products/jack-146.html Available from Mouser, part #502-760 for 2.38. It is very high quality part and fits perfectly. I manufactured an item using this part. It was a very difficult application, dust, moisture, high current, physical abuse. I sold over 2000 of them with never one problem. I gave a lifetime guarantee. Yes, I know it is just a plug, but the metallurgy prevents corrosion and the solder tabs are large, it is designed for high current, up to 5A. The handle is screw on, with plenty of room inside for amateur soldering style. Avoid junk Chinese made parts from Radio shack. They are not designed to pass current above 100ma. Hot (red) goes to the center pin, on the 760 plug that is the short solder tab. Use your voltmeter, set to DC to check the polarity after you are done soldering. Stick the red probe into the hole in the end of the plug and then touch the black probe to the sleeve of the plug. You should get 5 volts POSITIVE. If there is a negative sign in front of the 5, you are wired backwards. Do this test on the stock power supply to learn what it should look like if you don't understand my story. Enjoy your new power supply. If is anything like mine, ohmygod what a difference. All the trouble is worth it. You will double the performance easily.

Some people must make a pretty good living selling those feet. I can hardly imagine spending $400 for an interface between a table and cd player, but people certainly do. There are lots of DIY methods you can try first to see what YOU think about it. One is the partially inflated inner tube, with a board on top, acting as a 'seismic sink'. Turntable manufacturers (VPI) realized sandwiching steel plate between mdf does a really good job of killing vibrations. That would be pretty easy to make yourself, especially squeezebox size. Other people cut tennis or generally squishy balls in half, which looks incredulous. I've seen people cut the bottoms off pop cans and mate two together with a ceramic ball in-between. I personally haven't gotten around to trying any of these, but as you say I'm not sure one needs to with a Squeezebox. The clocking mechanisms may be candidates for dampening, but even that is up for debate probably. I just think there are lots of other tweaks concerning the SB that come before vib isolation. -- Skunk Skunk's Profile: http://forums.slimdevices.com/member.php?userid=2685 View this thread: http://forums.slimdevices.com/showthread.php?t=20838 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Those "feat" for under cdp's are to prevent vibrations going into the unit as much as possible, to let the transport have as much of a clean run as it can get.

I paid a lump-sum to my A/V installer, which included running wire for in-ceiling speakers (Proficient Audio, pretty decent BTW). Surfing the net, seems the amp sells for about $240, but I think I got it for a little less. I'm running the SB analog out to the audio in of the Russound. I mounted the amp on the back of my bedroom dresser, virtually invisible. In a kitchen, it could go on top of, inside, or under, cabinets. The Russound Auto Power On/Off has an adjustable time out, which I had to tweak a bit. I am also using the Slimserver Pre-Amp Volume Control, to allow me to keep the volume scale 35-40 for typical listening. -- sleepysurf squeezebox2 (with elpac wm075-1950-760 linear psu) direct to amp, 300gb buffalo linkstation (remote flac audio file storage), sunfire cinema grand 200 ~five (vertically bi-amped) driving martin-logan aerius i's, blue jeans cables.
