For the top end I think the Classe 70 (or a Classe ten) would be the first choice, followed by the ARC D-240. Although I'm sure others might put the ARC at the top of the list--it's really a close call and depends on personal preferences. I have owned ARC in the past, but now own both a Classe 70 and 10. I really like the Classe stuff. It performs flawlessly and reliably day in day out. I also think it is a very good value (particularly used).
Parasound HCA2200II , Yeah or No-Way!
I am in need of an amp, used(older is ok) for my biamp custom speaker. Each cabinet has 2-12" woofers, 2-6.5 midbasses and a tweeter in the D'appolito/MTM array..all of high quality. Very similar to Dunlavy 5's or 6's. I am using an Adcom GFA-555II to power from approx 80hz to 20hz, with an electronic Marchand active crossover. I am in need of a solid state amp (under $1000) to power from 80hz-20,000hz and dont know what to do. I cant use tubes as I pick up radio interference from a CB tower several houses over. Speakers are 94db/1watt/1meter,but I am a volume freak at times and like to play it at concert levels(115-120db), with all types of music. I am considering Muse 100, Aragon 4004 MKII, Parasund HCA 2200II, ARC D-240,Classe 70,McCormack DNA-1, Musical Design D-140i, etc. Which of these amps will give me a smooth tubelike sound without being euphonically colored too much, or does anyone know of some other amp I need to consider. My other equipment is a Linn LP12/Vahalla/Circus/Ittok/ClearAudio Signature turntable, NAD 502CD, Hafler Musical Concepts Preamp(decked out), 2- Chang lightspeeds filters, and quality cables. Please be as honest as possible. I need some help very desparately!!
