What are the most under-appreciated products?


What brands of audio gear have you come across that were great, but that most of us haven't heard of?

I'll start with Cayin. Ever heard of them?

David Berning products, way ahead of their time. I have never before seen such advanced tube circuit designs, utterly impressive engineering and sonics.
My speakers seem to be very obscure, at least un the U.S., check out www.sehring-audio.de

Sar Labs or Scientific Audio Research Lab...
A one man operation and his flagship power amp ..the Mos 400
is produced at the rate of two a month.
Great sound at half the price.
No, I'm not related, just a satisfied customer.
Herbies Hal-O tube dampers. I was amazed at how they increased the 3 D spacial characteristics, plus tighter and deeper bass. It was like getting an amp upgrade.
