Take a look at the Transcendent Sound Grounded Grid tube preamp. I've been enjoying mine and think it's a great value. I don't have experience with the others mentioned, but this may at least give you something else to consider.
New tube preamp
Recently upgraded speakers (Audio Physic Virgo III's), so now I've got a little upgrade fever.
Current amplification is a PSE SL preamp and PSE Studio V stereo amp. Thinking it might be good to go with a tube and/or hybid preamp.
I think I've narrowed it down to a PSE HL 1 hybrid, or Audible Illusions Modulus 3 -- both are around +/- $800 (and there's a couple of 3A's out there for about $1200).
Any suggestions about these units and the amp/speaker combination.
Thanks for your help.
