Hi all ! The Carver amps are a heck of a lot better than their preamps . The TFM 35 I had sounded pretty good , not great but good for the price . The preamp ( cant remember the model ) was horrible , no dynamics and very veiled . Didnt really notice this until I put an ESS preamp in the system . After looking at the Carver preamp it was obvious what the problem was ...the whole power supply was no bigger than a walnut , well maybe 2 walnuts but I sure was tiny .
