Preamp advice

If the OP is going up the price range, then the Allnic preamps would be something to consider. Very resolving and holographic, these are usually opposite characteristics.

BTW - the $500 Schiit Valhalla 3 OTL/OCL I mentioned previously is used by me as a preamp only.

Kunalraiker go to TMraudio.com they have Galion TSA 75 used. Hopefully it is still available.

Yyzsantabarbara, my guess the Galion Navy preamp will be as good as the Allnic ,my choice for less than 10k.Thomas spend times to voice his preamps and he uses premium parts as well. His P75 preamp I heard from a friend house is stellar $1800 . It is blessings to have a Tomas in this hobby full of experience and passionate on our hobby. Kind and not greedy.

What do you guys think about NAT symmetrical tube balanced preamp?

I don’t see that you mentioned budget, but the BAT VVK-52SE or 53SE are reference-level performers that can be found used.  If you can stretch there is and end-game BAT Rex Preamp for $7k on USAM.  53SEs are asking the same money.  The value play is the VK-52SE which I normally see sell in the mid-$3K range.  I’ve owned all three and now own the two-chassis Rex. They’re well-built and sonically hard to beat.  Plenty of reviews available to help you decide.    

Otherwise, get the best ARC Reference that you can afford.
