Looking for a new Amp or Preamp? If you're after tubes, post over here.

RE: thanks, It's interesting they stopped putting tubes in the pre amp section

I haven't had many opportunities to compare my amp to others. Sad to say but the KC-Lawrence-Topeka area is sadly lacking in B&M stores these days. I don't know of any dedicated listening rooms in the few stores that deal in audio. If they're out there, the stores are keeping the rooms secret.

Peachtree's reasoning for eliminating the tubes in the preamp section is that their new products such as the Nova integrated have a much greater s/n ratio through better engineering. Adding a tube, they say, would decrease the s/n by 10dB. However, the Nova amps have a loop function available for an external tube buffer or other devices.

"Previous generation Peachtree preamps had a signal to noise ratio in the range of 95 to 100dB, similar to competing preamps. When our signature tube buffer was engaged to smooth out a rough recording the S/N dropped to 88-90dB, an acceptable compromise for the sonic benefit.

By contrast, the newly-designed preamp section in the nova150 has a S/N ratio of 111dB. This is unheard of in its price range! Taking that 111dB S/N down to 88dB with a tube follower would sound like you'd thrown a blanket over your system."

It works well for me.
