which amp will sound better xpa 1 or Khartago

You would have to make that decision yourself.Don't rely on others to tell you what you like.Just a thought.Good luck.

Pretty much as above (thanks, Tpreaves) - though I can comment on both so I'm gonna. I bought the Odyssey used on what I thought was a spectacular deal - way under 1/2 price for the Khartago and right now it's running the front pair from a Pio receiver. I happen to like that sound a lot - but that's probably as much due to spending some serious time dialing in the overall system. That said - I've also thought about something like an XPA-3 and just from a pure price perspective have to consider that an upgrade. Emo is having another of their usual sales - and I'm so used to those numbers that I now consider the current numbers to be their "normal" prices. $529 for XPA-3 or $709 for XPA-2 shipped should be enough for what I need in the den.

As far as the "sound better" part - sorry, but I'm in that camp of most amp sound differences are either inaudible to mere mortals or completely one's personal preference. I think it's much more the overall system and once you get to an acceptable level of power and competence the extra $$$ could be much better put elsewhere (like in source material).
