If they were 100% level matched, using a switcher, yes I would surely still hear the differences, but even more. Like I said, it's quite obvious. Not taking away that this little A08 is excellent for the price. Without question my 6000A sounds better. At really low volume, the difference is harder to tell apart. At higher volumes, the 6000A kicks the A08's ass by a fair margin. Funny that you find it so hard to believe. I have had quite a few different amps in my system and they all sound slightly different. Maybe the Denon and Marantz AVR's sounded similar, except the Marantz SR7200. I think partly the Toroidal transformers.. made a difference there. The Denon PMA-800ne was good too but sold that and kept the Audiolab 6000A. Really liked the ATI amps I've had too. Again, I think which speakers you are using makes a big difference. My $5K speakers are really good, extremely revealing. If powering some decent $100-1000 8 ohm speaker, the differences are less noticeable. I have tried that too, have a set of Boston Acoustics Soundware for outside, Audiolab is still better on those but I am perfectly happy with the A08 on them.
