Im not surprised, you have to give it some time.....I don't believe A/B type test work. I had Odyssey Monoblocks, and NHT 3.3 and a Wadia 850cd player direct into the amps thats a high resolution system. Just for fun I replaced it was a cheap apex dvd player and suddenly my heart sank I heard no difference on at least the first 4-5 songs I listened too.....
But as time went on I did notice bass slam was all but gone and on certain uptempo songs the pace was lagging...maybe you have to give it some time and go thru each cd player for a week at a time most differences are quite subtle and will take time to discover...
