Budget power amp for Promethius TVC and Quad 22L

Are there any other solid state amplifiers at reasonable price works with a passive TVC?

I agree with Ngjockey about the gain issue.

Gain (i.e. amplification factor) is not very important in this context, and you have already opted for ~100W capability for the amp, so stick with that for now. However,

A TVC, or any passive device for that matter, needs an amp that is very easy to drive.

"Easy" simply means the following: the input impedance of the amp should be "benign" (high) -- a rule of the thumb is, 10kOhm or more.

Likewise and usefully, the output impedance of the source connected to the TVC (i.e. cdp, phono, tape, whatever, connected to the input of the TVC) should have be low -- rule of the thumb would be 1kOhm or less.

A practical way of determining if the set-up is correct electrically is simply to listen to mid-bass & upper bass energy. If it is notoriously lacking, there is incompatibility usually termed as "mismatch" in audiophool. WHat that means is, the source + TVC are outputting insufficient energy to drive the amp. ANother amp may sound excellent, with the same source+TVC -- simply because its input impedance is higher.

I received my TVC and so far I put around 150 hours on it. It sound's little bright and lean when connected to my AV Receiver line stage (47K ohms input impedence) and to my headphone amp(headsave classic connected to Sennheiser HD 555) with a volume control.

Can any one explain why the sound is bright and lean?

If I connect to a poweramp, am I going to get a warm and detailed sound?

What are you using as a source?
AV Receiver line stage..what is this? The TVC will not hide source or amplifier deficiencies. It is very easy to put together a poor matching of components using a TVC.

I've never heard a receiver that sounds good with music, accept for strictly background listening.

A TVC will need to break in just like any other piece of equipment. And each tap on the transformer will have to break in individually. Just be patient.
