Now that I've had the time to give some serious listening time to both the M500t and the TFM-55s I have a couple of observations I'd like to share.
The M500t is one hell of an amp, which probably explains why Bob built it for almost a decade. It is sonically neutral, with a broad, deep and defined soundstage. Bass has serrious SLAM, the mids are silky(especially strings and the female voice) and the highs are crystal clear without the grunge I hear on alot of systems. My Carver Silver ALSs are power hogs but this amp will take them as loud as I want to hear it in my 18X24X7.5 livingroom.
The TFM-55s have all of the same characterisics of the M500t except they are just a tad brighter in the upper midrange. Now this might be a residual of the HUGE dynamic range they provide my Silvers in the bridged mode. I was watching Will Smith in 'Enemy of the State' Friday night. One scene there was a break in and glass getting broken that sounded so real our dog Maggie(a Beagle and Jack Russell mix) went nuts trying to find it.
I'm finding that SERIOUS power(massive headroom) is something I don't want to live without. It brings a level of reality to the presentation be it music or HT that is missing in most cases.
If you can, get thee an M500t, it's a very musical amp. It does nothing wrong and everything right. Like the street there's no substitute for power. My pair of bridged TFM-55s have it in spades. Running the ALS Silvers with these has to be heard to be believed, the dynamics, bass slam, velvety mids and shimmering highs make the experience something I plan to treasure for a long time.
My system was sitting unused for years. I'd look at it, and maybe put on the headphones and listen to a CD or an LP once or twice a year because I couldn't find anyone to repair the amplifiers or my ribbon. Now I have a new ribbon(thanks Dave S.) and the TFM-55s are back in the fold(Rita and Mylinda did wonders) and would like to extend my humble thanks to the Bob Carver fans here for making it possible.
Thanks for getting me back in the mix guys......I'm diggin' it!
