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?

I'm currently living in exile with only an outlaw audio receiver for company, we thought home theatre would help pass the time. (Not much to do here on Elba) Except for the semi-annual Armageddon type blockbuster, home theatre is still just TV. Recently fell off the wagon and bought a pair of Kestrel's. Now I'm wondering about outlaw front end and tube amp. Heard about the Arcam's with an HT input, but I don't know if I want integrated and with CD's, tubes seem attractive. Some of you seem to live in countries which have actual hi-end showrooms, hoping for advice. Only good ears need apply.
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.
I don't think you amps are a problem. I second Trelja's comment that your system seems to be well balanced and any true improvement in sound quality would require a rebuild from the ground up. As such, I would suggest you stick with what you got. On the principle that a system is only as strong as its weakest link, simply replacing you amps will only marginally upgrade your system's overall sound quality.
