Schiit Audio Buf Coherence™ Tube Buffer

Buf
Coherence™ Tube Buffer

Bored with sterile sound? Add rich tube flavor with Buf!
Music Beyond Numbers
Yeah you got lots of zeros. But are you enjoying your music? Buf makes it easy to add tube sound to virtually any system. Go ahead and try it for yourself!

Affordable But Serious
Buf’s low price hides real tube cred. Buf is serious, with a unique Coherence™ output stage, 100V on the tube plate, Panasonic film capacitors, and a 100% linear power supply. No op-amps or switching power supplies here!

Unique Flexibility
A tube buffer with gain? Yes. Coherence maintains absolute phase, and offers gain if you need it. That makes Buf more flexible than other tube buffers. And, it’s easily switched out of the system…just turn it off!

Roll Away
Buf ships with an NOS 6N1P tube. But if you want to roll, you have options, including 6922, ECC88, and 6DJ8.
