I want to upgrade my front left/right amplification. I have narrowed it down to two possibilities; TagMclaren 250 by 3 or the Bryston 4BSST. The Tag can be picked up at some great prices and of course will integrate perfectly and be controlled by my processor through the bus as well as allowing me to drive all three front channels. On the other hand the Bryston has an awsome reputation and a bit more power . However the Tag ABX test showed that nobody could tell the difference between the two Does anyone have any advice? Or would neither be a big upgrade over my current Musical Fidelity biamping configuration?
