Preamp Opinion


A couple of weeks ago, I asked for advice on my amp and preamp. Although I am sure that it could be improved, I have come to the conclusion that the Parasound A23 is the least of my problems. I also have a Parasound New Classic 2100 preamp, a Marantz 8600 CD player/streamer (which I also think doesn't need to be replaced), and Focal Aria 926 speakers. I did listen to advice I was given and am expecting a vintage McIntosh SL-1 sub to my system.

I am looking at a few used preamps and wanted to get your opinions on them since the only one I have heard is the Adcom GFP-750 and that was years ago. My memory is that it had a very good sound to it. The other preamps I am considering are the Rotel RC-1572, Rogue RP-1, Coplant CTA 301 MKII, Bryston BP6, and Vincent SA-T7. Unfortunately, I have not heard any of them and don't have a location where I can. I tend to prefer a sound that is not too bright but provides a good clear soundstage and imaging. I have always owned solid state before and am a little leery of tube maintenance.

Thank you for your advice or observations about any of these preamps.

for decades i was leary of tubes, finally gave it a try in preamp and phono preamp.....FANTASTIC!!  also rolled a few tubes, WONDERFUL!!
I got an RP-1 and like it. I put in a set a matched Mullards after one of the stock ones crapped out at about 24 months. Mullards still working good after several years.
Never owned a Bryston Pre but I do have their BPD π. I like their gear even though the BOT-1 was horrendously over priced for what you actually got. Bryston have good support and a very active a loyal community over on Audiocircle.com . BUT. Isnt the BP pretty old?
The one at which I am looking was manufactured in 2017. I am sure that either the Rogue RP-1 or the Bryston BP-1 will give me an improved sound over my current Parasound, just hard to know which one to grab. I wish it was like the old days when I could audition each of them with my equipment. 
Thanks for your help!
Its not cheap and not expensive. It's new though, 5 year warranty, 30 day trial period, SS design from Benchmark Audio in NY  All Balanced Benchmark LA-4 line preamp. Stats are incredible and so will your sound be. Take a look, you wont be disappointed.. Robert TN  they also have a pre amp that has a GREAT headphone amp inside, don't remember the model though and it's more money though.
