Re: [SlimDevices: Audiophiles] Power supply A/B
I haven't tried anything other than the stock powersupply with my SB3 yet, but I did notice the very narrow soundstage compared to other transports and sources. I put one ferrite chokes around the DC and the AC portion of the cords, it opened it up a bit. Will build a filter for the DC line in a few days. -- Dazza Dazza's Profile: http://forums.slimdevices.com/member.php?userid=16416 View this thread: http://forums.slimdevices.com/showthread.php?t=47658 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Power supply A/B
There might be a small difference between the two SB3s as well, components sometimes change due to prices and availability.

Re: [SlimDevices: Audiophiles] Power supply A/B
Whilst taking on board your point about the hyperbole, to be honest I was simply trying to describe what I heard. I remember being stunned by the improvement, which is why that review cost me loads of money, because I ended up buying the entire set of cables and the Hydra. I had to send it off for photography, and as I recall to another reviewer, and going back to more standard cabling was a complete letdown. It was agony waiting for them to return to stay. I still use it today, even though Roy Gregory reckons I would be better off using Nordost mains cabling to create a system wide consistency. One thing we never got round to doing, was to directly compare the Nordost and the Shunyata cabling. What is interesting about the Shunyata cables, is that they are one of the few esoteric cables to be used in professional studios, including Dave Gilmour's. -- bigfool1956 David Ayers Music is what counts, hifi just helps us enjoy it more bigfool1956's Profile: http://forums.slimdevices.com/member.php?userid=13782 View this thread: http://forums.slimdevices.com/showthread.php?t=47658 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

[SlimDevices: Audiophiles] Power supply A/B
I just hooked up 2 SB3s to my main system. One with an Elpac and one with stock. Just for the hell of it (please refer to this statement when you want to tear me apart!) I did notice that they sounded different. Source material: Norah Jones, Steely Dan, Larry Coryell. It took me a while (like 30 mins) to see what was going on. Of course, they both sounded fine, but I wanted to see if I could identify the specific differences. My first thought was the Elpac was producing a blacker background. My second thought was that the stock sounded pretty good. I began to enjoy the stock. It seemed like there was more information present, but eventually I began to think it was bright. The problem was, it seemed to present more information. So I started to identify instruments in my A/B. There it was. The soundstage with the Elpac was wider. The soundstage with the stock was more congested. All the information was present, it was just better spread out. The stock seemed to grab my attention with more concentrated music, but once I identified the issue, I liked the Elpac better. The stock seemed louder in comparision after I figured it out. I had a similar experience A/B-ing my high powered amp and my $300 yammy receiver... They both sound good, but there were small incremental differences that I slowly identified and around which I generated preferences. But now that I know the differences, I can spot them. (yes the big ol amp won out.) So the stock is now back in the bedroom, happily powering a great sounding pair of eras and the Elpac is in the main system. BTW - I got the Elpac with a 3rd used SB3. I had no intention of getting it. I just ended up with it. I am not going to recommend anyone go get an upgraded power supply. -- roll - gybe roll - gybe's Profile: http://forums.slimdevices.com/member.php?userid=8975 View this thread: http://forums.slimdevices.com/showthread.php?t=47658 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Makes me glad that my S.O. is geek enough to think proper testing is a good idea. We spent some time the other day doing A/B tests for some new speakers. It was not a DBT because we could tell which pair was active. We did take turns flipping tracks and speaker sets for each other.
