[SlimDevices: Audiophiles] Re: brand new 5V 6A linear power supply source
I purchased a 5V 1A linear power supply to evaluate the difference between stock and upgraded ps on my SB3. I popped open the stock ps and it seems to be quite well built. The aftermarket ps has a less involved circuitry but a considerably larger transformer. I am very familiar with the performance of my SB3 and in my system the internal dac of the SB3 is superior to the dac in my receiver. I also use the internal dac on my cd player for my comparison as it performs better as well. The driving force behind the upgrade was a definite lack of detail and depth on the SB3 playing Apple Lossless Compression music compared to my cd player. The SB3's performance has improved to the point that the difference is far less apparent. Detail and depth are improved and most of the difference in the presence is due to the output level of the SB3 being down slightly. I am eager to try an outboard dac to see if I can exploit the SB3's performance even more.

At 1A, do you think that may be a bit low for the SB? Is it getting really hot when in use? Also, I believe you saying, that the new PS has caused the output of your SB to be less loud than with the stock PS. If so, I wonder if this implies you might be overtaxing your new PS.

[SlimDevices: Audiophiles] Re: brand new 5V 6A linear power supply source
I don't know how many of you folks are aware of it, but not all linear regulators are created equal. An ideal regulated power supply should look to the load like an ideal voltage source. That means it should supply any amount of current required to maintain the constant voltage, regardless of what the load is doing or how fast it is doing it. The impedance of the supply should look like 0 Ohms over an infinite bandwidth. In the real world, the impedance should be very low over at least the audio bandwidth. If you really want to know if a linear supply matters, build one with a Jung super regulator. It is about as close to ideal as you're going to get. Check google for the circuit. I believe the transporter uses Jung regulators to power the audio circuits.

As with speaker cables and interconnects, however, the 2 or 3 feet used to connect to your SB3 won't have any practical effect. Thanks for the clarification. I would prefer to have the regs in the same box as the load, but of course that means reboxing. The standard recommendation seems to be keep the cable really short, but maybe that's for noise rather than impedance. I don't expect it to turn my Sb3 into a Transporter, the on-board implementation in Transporter is sure to be far quieter (in fact I think Sean may have measured an Sb3 with off-board superregs but I don't remember the results).

Linn for example. The most popular theory - that I agree with as well - is that switching supplies create RF interference that can upset other parts of the system (eg amps, DACs) that are not as well engineered as they might be. Certainly the stock unit (UK model) produces lots of RF - you can't use one near an AM radio for example. If the RF gets onto the SPDIF signal it may make the signal harder for an external DAC to handle accurately. For those using the analogue outputs, obviously the quality of the supply is fundmental to the quality of the output stage of the internal DAC. Whether you will hear the difference on 192Kbs MP3's I don't know - I don't have any. I'm sure someone will know...

Others, such as myself, perceive no difference. The audio circuits inside the SB3 are powered from a DC-DC converter inside the SB3. A DC-DC converter is a type of switching power supply. Even if you use a linear supply external to the SB3, the internal switching supply remains. There have been numerous threads on this subject, and Slim Devices people even made a bunch of measurements that actually looked microscopically better with the stock switching supply. In short, if you WANT to hear a difference, you probably will, and if you don't really care, you probably won't.

Thanks for the pic. :) Yes, the RatShack connector is a flimsy POS. I believe those were my exact words as I struggled to attach the wires to it without breaking the tabs. The Switchcraft(part no. 760?)is less than $5. . .$3.08, but Digikey has a $5 handling fee on orders less than $25, so you're probably looking at $10 with shipping. You could put together a $25 order to save the $5 handling fee and distribute the shipping cost among several items, but that's a different project. The RatShack was there. I bought it. It works.

I have an aversion to any soldering/fiddling that may be necessary. Thanks in advance. No. A 5-pin DIN connector looks like this: http://www.maplin.co.uk/images/full/24516i0.jpg But the Squeezebox's power plug looks like this: http://www.hardware-one.com/reviews/nexland_pro800turbo/power_adapter_110V.jpg You would have to solder. It would be easy, but there's no way around it. -- Mark Lanctot Mark Lanctot's Profile: http://forums.slimdevices.com/member.php?userid=2071 View this thread: http://forums.slimdevices.com/showthread.php?t=30703 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Well.. there is crimping, which isn't soldering- but you'd need a multimeter to check polarity, which is fiddling. -- Skunk Skunk's Profile: http://forums.slimdevices.com/member.php?userid=2685 View this thread: http://forums.slimdevices.com/showthread.php?t=30703 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Thanks for the rapid replies. I would like to give a linear power supply a try at some point but I am not entirely convinced by the arguments put forth in support of the Bolder modded Elpac. That is not to say that no difference exists... Ideally, I'd like to test out any potential improvement for a low-cost price. If there is any improvement, I would then consider purchasing pricier options. So, with that in mind, any plug and play, inexpensive, linear power supplies readily available these days?

El Duderino/OtoDoc I believe there is a substantial difference between the standard PSU and other alternatives for a SB3, at least on my system. I've tried linear supplies, batteries and a computer PSU. I wouldn't dismiss any particular topology because one example wasn't good. For example, my old $5 XT computer PSU sounds very good, as good or better than other options I have tried, but it does introduce hum and other very unusual background noises. Different regulators also seem to make a difference. Forget about argumnets, you need to try for yourself to see if you can hear a difference. BTW: I'm using my Transporter as a benchmark. regards Greg -- Greg Erskine Greg Erskine's Profile: http://forums.slimdevices.com/member.php?userid=7403 View this thread: http://forums.slimdevices.com/showthread.php?t=30703 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
