Woo Audio WA6

Woo Audio WA6

“ I'm a relative newbie to the headphone game.   My reference system (at the time of writing) is a Burson 160D, and having a good reference is essential when you're comparing tubes.     My reference headphone (at the time of writing) is the Sennheiser HD 650, which are known for their veil until you put great amplification with them.  I also own UERMs, which aren't...” --reeltime

“A Tale of Two Tube Amps Woo Audio WA7 and ALO Audio PanAm       My normal gear preference and choice for many years has been solid state. I have held a curiosity, however, in tube-based audio gear and the possibilities and presentation that comes from it. It might be considered ironic that considering how endlessly I have been fiddling with my main system for years now...” --Currawong

Woo Audio 2

Woo Audio 2

“The WA2 is a five-star amp sold by a two-star company. The amp itself is a marvel of engineering, built on a Bauhausian aesthetic: form follows function. It's pretty to look at, but, properly upgraded, infinitely prettier to listen to. With dual driver, rectifier, and power tubes, it's possible to sculpt and finesse sound signatures: several reviewers have already noted that the amp lends...” --Chesterfield

“[This is copied from the Music City Meet #3 Pics and Impressions thread, post here.]    A Few Impressions of the Woo Audio WA22     Intro: Mike at Woo Audio was kind enough to lend me the use of his WA22 for the Music City Meet #3 and a few weeks before. As it happened, and to my dismay, I did not get to spend the amount of time with the WA22 that I would have...” --Theogenes

Woo Audio WA 6 SE

“ I recently had the opportunity to listen to WA6SE on demo for 2 hours at the comfort of my home and this is my take on it. The DAC is DACport and the headphone used is LCD-2 Rev 2 if anyone is interested to know. The actual amp consists of 2 separate units; one is the actual tube amp while the second unit is a separate power supply to the amp. The 2 units would then be connected via a...” --Joe-Siow

Woo Audio WA5 LE

“ Product Standard Build Woo Audio 5 LE Headphone Amplifier   In this day of mass produced equipment it is nice to find a small boutique headphone and headphone amplifier company who are sincerely into it. So how does the selection process work? The big question is which amplifier to have these guys make for you, and why?    I have had tube equipment forever. My first...” --Redcarmoose

Woo Audio WA3

Woo Audio WA3

“ I had the WA3 in about 2005.  It was a great amp with my Senns... not so much with my Grados.  It had all the great sound qualities of a fine OTL tube amp, especially with the Tung Sol 5998 / 7236 rectifier.  Anyone would be very pleased with the WA3 / WA3+ to drive their high impedence phones - but, I'd rather have a tube hybrid, or TC tube amp to drive my Grados / Denons /...” --Gradofan2

The WA3 achieved high standard of Woo Audio build quality, high performance and yet affordable. Its compact size offers both headphone and pre-amp capability. If one ever look for a best value product for high impedance headphones or a true pre-amp, look no further.
