Best head amp of the market ?

ZYX CPP-1 http://www.sorasound.com/products/zyx/zyx-cpp-1-pre-preamp/

Dear @harrylavo: SA-2 the finest?

Well, in my first hand experiences because I owned nothing can " touch "/comes close to the Classé Audio NIL-3.

Its separated power supply in reality is an amplifier power supply  and the separated lectronics comes in a true " bunker " where all the electronics comes not only covered by something as solid silicon and inside a bullet proff metal shield against any disturbances of any kind and this comes inside the heavy metal external box/chassis. It's not only a beauty of design but ejemplary high quality ececution to that top design. As I said nothing can beats till today.

Unfortunatelly I sold it years ago.

Here it's a good opportunity to have it:

That's is the FINEST. Period.

But exist many good alternatives along the ones all of you mentioned to that fabolous Classé Audio headamp like: Denon, Accuphase, Linear Technology,Audio Device, Eureka, Fidelix, Mactone, Pionner,  Klyne, Yamaha, Ortofon, Levinson, Mcintosh, Music Reference, Precision Fidelity.

Yes, all vintage ones but always it's a better option to SUTs.
