I think I have a good example of when a passive pre works. 100 dB speakers PASS XA25 with 20dB of gain. 1.25V will run the amp at full power. The lowest active preamp I could find was 5dB. Even now with this passive setup at times I only need to turn it up to say 10AM. An active will change the sound I know. Are there active solutions for my setup? I don't really want to mess with tube amps. Tube preamps would sound OK but too much gain might make my volume very sensative? I think.
The Best Preamp is no Preamp?
So recently I've discovered the possibility of completely removing my preamp from my rig. I've never heard or considered this before, so much audio tradition... But in going directly from DAC to amplifier the sound quality is absolutely incredible, instantly had me grinning. Using music server to Chord M Scaler to Chord Qutest (cut out Marantz SR5015) to go directly to dual Emotiva XPA-DR1 monoblocks, to GR Research's 24 strand speaker wire to Magnepan 1.7i's. Only difference is running volume on server vs Marantz remote, sound quality is the biggest jump I've ever heard with any gear.
Have you guys had experience cutting out the preamp from your rig? What's your thoughts?

I currently have a VTA SP12(bob latino) It is currently running passive buffer with 12AU7 Tungsol. All it takes is change one wire and I could have active. It has remote volume, but I doubt it’s anything special. @ozzy what is your definition of "good" amp? Thanks |
