Woo Audio WA6 2nd gen Vacuum Tube Class-A Headphones Amplifier (Black)

Wonderful headphone amp..well built..I love the sound...

Amazing.

I have owned the WA6 for about one year now and is the 4th dedicated headphone amp I have owned. I started with a Creek OBH-8 transistor unit, followed by a ASL MG Head MK3 ( tube ), Perreaux SHX-1 Class A (transistor), Cayin HA-1 (tube ), and now the Woo Audio WA6. I find the WA6 offers the best combination of excellent sonics, versatility, and quality construction vs the amps I had before it. I use it with Denon AH-D7000 ( low impedance ) and Sennheiser HD600 ( high impedance ) headphones. The WA6 has a switch for low and high impedance phones and drives both these headphones with smooth frequency response. I am using vintage tubes and HIGHLY suggest you get rid of the cheap Chinese tubes that it ships with. I also decided to buy the optional 6SN7 socket adapters from Woo as I love the sound of these tubes and the large variety still available. My favorite 6SN7 is the Ken-Rad. I use a Mullard GZ32 rectifier. Sound reproduction out of the WA6 with these tubes is warm, solid, with a huge soundstage, The WA 6 manages to offer much of the dynamics found in solid state amps and the warmth and smooth natural presentation of vacuum tubes combined. When you factor in the solid construction and quality parts that Woo Audio offers, the WA6 is a true audio bargain - highly recommended.

find the right vintage tube and this amp blows your brains out!
