With regards to the blind test, it wasn't people "thinking" they heard a difference, they did hear a difference, period. That is what a blind test is for. whether that's due to poor AC power is irrelevent to the test . The test was to determine whether the modded elpac sounded better than the stock ps in that system. It did, period, blind and ,therefore, not a result of listener bias or "belief". The test was not done to determine "why" the elpac sounded better, simply if it sounded better in those circumstances. The fact that the test was done in a system with dedicated lines and a power conditioner could imply that many people might(but not necessarily) hear a difference in their systems and ,therefore, it might be worth the modest investment to try out a different power supply. BTW, the blind test used 2 SB3's with the same brand interconnect to the same pre-amp. After 2 rounds the PS's were switched to the other SB to rule out differences in the SB's (our girlfriends were mad so we had a lot of time on our hands:-) You are mis using the poor AC thesis. Poor AC does not affect or invalidate the goals of the test. Both PS's were plugged into a power conditioner which in turn was plugged into a dedicated line. You can't get much cleaner than that unless you go to battery power. I don't think anyone on this thread was saying that poor AC was a variable affecting the validity of this test as , say, using different interconnects or pre-amps would be. Both units were plugged into the SAME power conditioner so there were NO variables vis a vis AC power by definition. I don't know how to be more clear than that. If you follow thatclearly irefutable logic I must conclude that you are purposely obfuscating, what puzzles me is why you would do that,but oh well, to each his own. So all of your so called variables were removed and,still, the elpac sounded better, which was my only contention in the first place. The improvement might be due to a further cleaning of power, who knows and who cares? the salient point is that the elpac sounded better in a blind test which ruled out the possibility of listener bias, belief or susceptibility to suggestion. Why don't you do your own blind test? Your results may be different. I would suggest you do this on a highly resolving system so you can rule out that variable. My test was done on watt/puppies with rowland electronics, which many consider to be pretty accurate. -- tomjtx ------------------------------------------------------------------------ tomjtx's Profile: http://forums.slimdevices.com/member.php?userid=7449 View this thread: http://forums.slimdevices.com/showthread.php?t=29058 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
