PS Audio PMG Signature Preamp or BHK Signature Preamp or Bryston BP-19

What specific improvements are you looking for?

I had the BP-19. It is true, it will not color the sound in any way and it is dead quiet letting the music come through clearly. Its precise volume control works well from the overbuilt remote.

The BP-19 convinced me that I did need a good separate preamp compared to my DAC/Pre setup.

What am I looking for? The BHK sounds very sweet & with a decent side to side sound stage, but is a little veiled & soft sounding. The minds are a little too thick & congested. Looking for better depth of sound stage, more open & better separation of individual instruments with more detail. I’m not opposed to a touch of sweeting. Would still like to retain a big full & rich sound.  I don’t want tubes.... Tired of chasing the depleted & pricey NOS stuff.  

Sounds like my history @stevehardy1 !  I had Classe, then the BHK then an Audionet Pre1 G3.  These are available now for around 3k and blow away the BHK.  https://www.usaudiomart.com/details/650245373-audionet-pre1-g3-preamplifier-with-remote/?ref=search&q=AUDIONET

I then moved up to the sweet spot in their line, the Pre G2.  I've seen them for less than this, but :

Holographic sound with warmth without tubes.

GTT Audio imports Audionet and is a great resource.

I'd really like to hear more from Bryston BP-19 owners for their opinions but it doesn't seem to be many of those units out on the streets. The few reviews I've seen are positive, but I've read some about them being a little thin. Love the 20 year warranty.
