To echo some others thoughts....yes....If you consider Sunfire with the Carver line. I own a Cinema Grand and love it. I personally think it is one of the most flexible bang for the buck amps on the market. There are better sounding amps and more powerful amps but not both anywhere near what you can buy the Sunfire equipment for. IMHO your best upgrade would be to find a dedicated Pre-amp/ tuner that you like.
Are Carver amps worth a damn?
i have a system which I use for both home theatre (70%) and for music. It is comprised of a Theta data basic transport, a Nakamashi cr-2 tape deck, a Marantz AV-550 preamp /tuner, a panasonic dvd player and a proscan vcr. For amplification I have been using 2 Carver TFM-35's and a TFM-15 for the surrounds. I have an unpowered sub so I get 1 channel of 250w to the front 3 and the sub, and 100wpc to the surrounds. For speakers I am using Definitives all the way around. Are the amps my current weak link in this system?
