My WA6 has arrived!
My "Audiophile Edition" WA6 was delivered late Friday afternoon. I was amazed at the weight of the package, and after unboxing, was surprised by the size/heft of this amp, which is actually a little larger & heavier than it appears (to me) in pictures. The transformer on this amp is massive! This is a very serious looking piece of equipment with an excellent fit and finish. (I ordered my unit in Black, to match my other equipment.)
After getting everything hooked up, I installed the stock tubes (Sylvania 6DE7 Triodes and a Russian Electro-Harmonix 5U4GB Rectifer). I'm not sure if these are the same tubes that Jack used when doing the initial testing/burn-in of my unit or not. I turned the amp on and let the tubes warm for about 30 minutes before feeding a signal from a burn-in CD. After another 30 minutes of burn-in CD, I listened to a few tunes to make sure everything was OK so far.
The midrange was clean and fairly smooth, but bass & treble were a little ragged on the edges. (What do you expect after less than an hour of burn-in?) The gain of this amp is a perfect match with my Sennheiser HD-650s! The volume range makes full use of the control, with Max volume being as loud as I would ever desire, but no more. (This allows for very good signal to noise ratio) With everything hooked-up and on (CD on Pause), and the volume control set a Max, this thing is quite. I mean dead quite! Absolutely no hiss, no hum, just silence! (Comparable to my FT Audio Passive Pre/Speaker System)
I will be burning-in the BG&V-Caps over the next several weeks (with FM tuner interstation white noise) before I attempt to give any serious evaluation. I will be leaving the stock tubes in for this initial burn-in, thereby conserving my premium tubes. I have had a Stefan Equinox LE Cable on order (16 week waiting list), which should be here about the time the initial Cap burn-in is complete. Then I will have to burn in the Cable and the premium tubes before I can set down for some serious listening.
Oh... here's a picture of the inside. (I just had to take a peek!)Only 399 more hours of burn-in to go!
