Line Stage Preamps that blew you away $2500 Edition

Benchmark +1.  Quietest preamp I have ever heard.  

New or used price?

If you can lay your hands on a used Backert Rhumba 1.3, it will bring smile on your face when you introduce it in your system and listen to it. Unfortunately they don't show up often.

@unsound  either or.

@milpai  I’ve seen a 1.1 and debated it. You’re right though, Rhumbas don’t show up often if ever.

I almost bought a Backert Rhumba, heard great things about it.   The most impressive thing about the Zesto is despite being tube it's super quiet.   99dB speakers, no signal, turn the volume to 3 o'clock and nothing... silence.   Not even the normal slightest high frequency hiss that you hear in most systems.   Complete silence .  From that silence comes explosive dynamics ,   the Zesto is incredible .  My former cj preamp was great, it served me well but this is in another league altogether.
