Granite Audio 770 Tube Pre-amp & its phono sec.

Currently own Supratek Chardonnay, Jas Array 1.1, TecT 2.0 and pre that belong to my boddy Cyber 222MK II. TacT is a RCS so it is not a real preamp. But the rest are.

My problem is this:
Love Supratek for its transparency, detail, speed (top end is to colored in my opinion - edgy)
Love Jas for emotional presentation and sweetness
Can not find a preamp that will give me both (under or around 2K used......or new). Does anyone know a baby " Frankenstein ".

At the time being, I ordered Granite Audio 770FP preamp to try it out. I would appreciate any opinion on that preamp. Keep in mind that I heard it many times - just not in my system. ( Consonance Cyber 800 mono block modded by B.Backert, Consonance Droplet 5.0 CDP, Quatro - vandersteen Spks. modded MMF7 Music Hall TT, Lenco (not finish - replinthed), TT "X" also home build turntable, Morch up-4/Denon 103R and Consonance Reference 40 phonostage. Cabling in 90% by Morrow Audio)
I would like to find out how its phono section compare to others etc. If non of these preamp will work - my only option would be to place it in hands of a tried and wonderful moder B.B to tweak it to my taste.

Thank You in advance

I just briefly listen to Granit Audio 770fp on Friday.
Can't say much about its sound yet.....holidays rush.
It sure feels different in bass region and a bit darker on the top & a little cleaner more forgiving but in the same time slightly less exiting......how different then Supratek ?
I will have to spend a little more time with it to answer that.
On top of everything it has to break-in for at least a week and the use of better NOS tubes might be in order (not questioning Dans' choice but I do understand his limitations to keep it within original budget). Morrow cables used as IC and Granit Audio 555 PC.
Cheers
and happy holidays.
Drive safe.

Happy listining
& enjoy the music.

I have owned a Granite 770R since May 07 (also have Granite interconnects combined with Purist Audio,Granite headphone amp and a Granite power cord). It's good to see some response on Audiogon for it is truly in my opinion one of those sleepers. I previously put in a thread on tube rolling and got no response. Don is absolutely one of the finest - hope he is doing well with his personal following. I only use the preamp's line stage. I found using NOS or vintage tubes makes a dramatic difference (have a mix of Tungsols, Sylvania and Audio Research tubes). The Russian Tungsols may work well. My unit needed about a 150 - 200 hour burn in period. Also I just tried running my CDP through the tape in and I think this helps out. I have had many fine preamps over the years(one in the 10K plus price range) and the Granite holds it own.

Yes , Granite is/was in the shadows but it is a really nice preamp:
very neutral, not in the way, a little heavy in bass region but I wouldn't blame it on preamp , since it wasn't broken- in yet. Fine product if you can get a good deal.
