"Min is THE MAN - these WE91 300B amps are FABULOUS and an incredible value
(compared to the best - Yamamoto, Kurashima, Shindo, etc.). Get them before his waiting time is 6 months!" - Paul
Folbrecht on WE91A 300B monoblocks with Hashimoto OPTs. Read his review on the amp.
Comments from Randy Morgan,
the second owner of the WE91A monos -
I am the proud owner of a pair of WE91a monoblocks that Min built for Paul Folbrecht in December of 2008. I was able
to trade one of Min's 6sn7/76/300B stereo amps + cash for them. I have had them in my main system for 2 weeks now, and
I am quite frankly blown away by the sound, power, and appearance. I am using JohnK built Fostex 208 sigma + Fountek ribbon
tweeter speakers, 98dB, a Martin Logan Depth sub, Juicymusic blueberry preamp, cdp, tuner, and 'table for sources. The
room is 14' x 18' with 9' ceilings, heavily furnished. The amps have very quiet, selected 6C6/1603 driver tubes with
those cool anode caps, EML 300b, and Chatham 5R4s. The amps are SO revealing and transparent I had to go through 7 pairs
of IC's before I found that some old silver dragons were quietest, almost eliminating radio station noise. I will be
the first to admit I am more neurotic than most folks about NOISE. I like quiet amps, minimal hum or hiss, and these
mono's are, yes, DEAD quiet. The amps themselves produce a quiet industrial mmmmm sound, just all the transformers working,
but inaudible from 8 feet away. I listen to mostly classical music, a lot of 20th century crazy stuff, but also Latin,
the usual jazz singers, Piazzolla tango etc. Just not rock, been there, done that, I am 54 after all.
I have been into low watt/hi-eff tube audio for about 6 years, spent and lost
a fortune on Audiogon, and have owned, shoot, 40 amps easily, DIY as well as big name stuff (Wavelength, Art Audio etc). I
still own 17 amps, too much too much, but I see them as works of art and my wife is glad I don't play golf. OK, the sound. Emerging from a very quiet backround,
I was immediately aware of the recording room acoustics: echoes, performers taking a breath, chairs squeaking-- all the low
level detail that provides realism. The sound is simply beautiful, instruments sound so real, transients are fast, and
the power is more than I need, but as much as I like. The 3d effect is startling, lots of air around each performer.
The sound, to me, is quite balanced throughout the audible spectrum, no apparent emphasis of lows/mids/highs. I
am enjoying them immensely needless to say. One of my favorite lines from audioasylum, when the rather silly question,
"what is the best amp in the world" was posted, is, "the one you don't own--yet!!" Maybe
I'm there, finally.
