Tube preamp for my Bryston 7B3

Budget?  What sound characteristics are you looking to gain and/or not lose with the tube pre?

Might look at Rogue RP series. Good value stuff. I have had the RP-1 for several years and really have enjoyed it. Put in matched Mullards from Andy at Vintage Tube Services. Match that with class A/B solid state amp and Focal 926.There is an RP-5 over on USAudiomart.
RP-9 on herehttps://www.audiogon.com/listings/lisabe08-rogue-audio-rp-9-stereo-tube-preamplifier-rp9-black-34670...
I had a listen at Octave at RMAF a couple years ago and their stuff is way impressive.

Octave also has this baby for even bigger $$ but very cool.

I'm using a Bryston 2.5 SST2 w/a Luxman CL38U SE tube preamp w/excellent results. 

If you have not done so you might check here at the Bryston forum on audiocircle.com

PS Audio BHK Signature Preamp has input stage tubes.  And they might even have a try and buy on that model.

Modwright Instruments makes pretty good tubed preamps. Don’t know your budget so from high to low price 1) LS300 is fully balanced pure class A… 2)  LS 36.5 DM,…  3) LS 36.5, … 4) LS 100… All of them made in US with 5 years warranty…output impedance is 100-110 Ohm, what makes them good match for your Bryston 7B3. 

Hi All,
Thanks for giving me units to research. Soix ...to answer your question...budget $3K - $6K (but doesn't mean I wouldn't like to spend less if it's a real over achiever).  I love the detail and dynamics I'm getting from my current system but have a curiosity about the "Tube Magic" others seem to love.Our hobby is kinda like poison ivy....you can do things to stop the itch for a while but without fail the itch returns. I'm looking at all your above suggestions......

tnx to all ...2bz.

I’d look at a Linear Tube Audio microZOTL preamp.  I think they may even offer some sort of trial period, which would be a nice bonus.  Best of luck in finding that magic. 

c-j or herron would be beyond reproach... and would provide sensational tubey magic without sacrificing the benefits already in the op system driving by bryston ss

Hi Goner's...

Has anyone tried Prima Luna (EVO 400 caught my eye but also heard good things about Cary too) and or Cary tube preamps with the Bryston 7B3 monoblocs...and what did you think.

Been very happy with my Bryston BP26 preamp but got the "Audio Itch" again.

tnx!

I use a Bryston 14b3 ss amp with a 6sn7 tube based deHavilland Ultraverve 3  preamp with wonderful results (the deHavilland has been upgraded with Dueland caps and wire). I have B&W 802d3 speakers.  The Bryston pushes these speakers with ease and accuracy and the deHavilland adds warmth and breathiness. Bass is deep and snappy.  I use a Purist silver clad copper 20th anniversary interconnect from my Holo May DAC to the deHavilland for sharpness and clarity. The I use an all copper Cardas clear reflection interconnect from the deHavilland to the Bryston. I use Purist 20th anniversary Purist speaker cables. My music sounds pretty incredible. I am 77 and have been into quality audio for over 60 years. I have heard lots of systems. When I listen to my system I often shake my head at how wonderful it sounds.

I own an Aric Audio Super 6SN7 preamp and also one of his amplifiers. . Cost of the Super is ~$4000. Aric has a great website and is great to deal with.  His tube preamps have a low output impedance and variable gain .He uses high end parts and can customize for one's needs.

Whether you end up purchasing from him or not, you will appreciate the effort of a phone call.
