Subwoofer Amp Recommendations

I've added a stereo pair of VBT Magellan passive subs (fantastic, BTW)to my 2-channel system. VBT recommends using their 200S amp, which I have---and it is good---and I could get another for stereo, but as I'm using a Tact 2.2x, I don't need the crossover/volume functions in their amp, and would rather not have to put the signal through another set of electronics.

My considerations have ranged from the new Carver Pro amps (but I'm not happy about their connections as I'd need new cables or adapters) to used Adcoms/NADs/Aragons. I've also considered PS Audio and Sunfire, but not sure if I need to spend that much just for a bass amp.

A friend suggested the new Panasonic 45 digital receiver which takes a digital input (saving me the expense of a DAC, but I already have an extra anyway).

Your thoughts and experience would be appreciated.

Ritteri...I guess I must be lucky to have no noise problems or QC defects. (Many, many excellent products are no longer made. There is another thread about this).

I don't think that you can explain the need for high slew rate when processing a signal that has no steep wavefronts. Any rapid signal change has been routed to another amplifier by the crossover. If your SW amplifier did output a rapidly changing voltage (characteristic of midrange or tweeter signals) your Subwoofer driver would not respond anyway.

Buy the Adcom GFA555 mkII in the amp section of the Gon for 350.00.Tons of power and quiet.I use two in bridged mode on my Adire Tumults.

My brother's L-07Ms keep powering his subs year after after year with no problems and they run cool. Of course if one lives in wicked cold New Hampshire a warmer running amp is welcome.

I also think response to DC is important. I have an SVS 20-39CS passive sub. I've tried both a Tandberg 3006A (264W/4ohms) and an Aragon 4004MKii (400W/4ohms) driving it. The Tandberg is DC coupled, the Aragon is not. On scenes with subsonic bass, like the depth charges in U571, the Tandberg shook the house a lot better than the Aragon.

In response to the L07M comment, I own four of them and have NEVER had any problems. Coming up on a 35th anniversary, I'de like to see an amplifier beat that.
