Hello,
I thought I'd add my two cents, My one-off Tannoy HPD 315's (12" Dual Concentrics from the mid seventies) sound gorgeous with an SET 300B, that puts out a very stout 9 Wpc.
However, I recently (out of curiosity) built a Class D Audio kit (CDA 254), @ 125 Wpc, when built as a stereo amp. I, however, took it a step further, and added a second amp module, and are running the two modules in bridged mono mode. In theory, they will output 500 Wpc this way, I'm not sure just what they output, when sharing the same power supply, as in my case.
The original kit was $430, and another $145 for the second module. They also sell complete amps for a fair price. My Tannoys love the power provided by this amplification, and sound nearly as good as they ever have, kind of like an SET amp on steroids.
It's an inexpensive way to try alternative amps, and it's great to have different amps to chose from, and to have a back-up in case of tube failure.
Regards,
Dan
