Who makes great active preamps ? Tube or solid state or hybrid.


It appears, it is not Pass, Rowland, even Lamm etc. Who then ? 
I heard about Ypsilon, though some say it is a little bright and forward sounding.

I have had an Ayon (bottom of the range) and was very good, but not quite great.  I currently have Emm Labs Pre2 and Daniel Hertz M6 and both are fabulous.
Audible Illusions makes outstanding tubed preamps. I'm waiting on an L3B as we speak.
Good luck with your search.
Thrax Audio Dionysis Pre. Sublime but big $$$.

And +1 Vincent for the money. SA-T8 Tube (as long as you roll in better tubes) & SA-94 Solid State.
MP-1 or MP-3  from Atma-Sphere you will never regret the purchase. It can stand hand in hand against those super heavily marketed companies out there.

The MP-1 is by far to me one of the very best, being in this hobby for 25 years heard and owned so many.
