Which ever one you like. All I can tell you is trust your own ears. If I told you my choice for best amp you may spend ten grand, get the damm thing home and think it sounds like shit! However, I would not recommend a Bi amp system.
best amp
Classe' or Aragon Currently using aragon in my system. I now have a larger romm and plan on geeting larger speakers i.e. Dunluvy, Snell A RS, Duntech ??? Anyways I'll need a larger amp. I like the sound of Aragon, but need to double power or so. Like the Classe' too, but have not compared side by side. Should I keep my 8008BB, add to it and bi amp or consider the Classe' 401 and up. Have heard Krell, Mark Lev. and Proceed. Recommendations please!!! Chuck
