Hybrid Balanced Tube Preamp?

You may want to look at BAT preamps.
Other fully SS preamps do not defeat the goal of good sound.To be honest and realistic, the place where tubes really make a big difference is in the output section. A signal from an SS a preamp is usually very clean and precise, the tube magic happens when the signal get amplified by the tubes in the output. Personally I would rather do that then flatten out the sound in an SS output but I am a converted tubophile.
Why are you avoiding more than 2 tubes in your preamp anyway?

I would buy something based on sound quality, build quality and how well it matches to your current components. Get that right and you won't have to worry about all that other stuff.

I think the "Coincident Statement Linestage" is just what you need.

I recommend the VTL TL-6.5 signature line stage preamp. It is a hybrid preamp, with two 12AU7 tubes. It is very transparent and very flexible. I have this running my Lamm hybrid M2.1 monoblock amps.

(FYI: This replaced the Ayre K-1XE preamp that I had been using for nine years. The VTL is slightly better sonically and much better functionally than the Ayre, but the Ayre was a full function preamp, with a near reference phono stage.)

Note: Tube rolling is fairly easy and cheap due to the minimal number of tubes and the type. I went with the very neutral RFT 12AU7 tubes, which are fairly inexpensive.

Good luck in your search!

Thanks guy - this is going to be my "to the grave" system i don't want to spend a lot of time and money rolling tubes, but i hear you - the least number of tubes i might be able to acquire in a preamp maybe a minimum of 4, for it to be actually a tube preamp (full fledged) but i was trying my luck to to see if there are any other tube manufacturers that employ a single tube in the input/driver section.

Although there are many who has been fortunate to have a hiss/grain/gain free experience with full tube gears, i have been not so lucky in my pursuits hence i would like to keep my tubes as minimal as possible.

Unfortunately CoIncident is not a balanced design, but looks like i am headed towards VAC,BAT,LAMM etc now..maybe even Atmasphere (but just too many tubes!)
