Yeah....... I know! I started into this looking at a WA3 for $470
(Told my wife I was going to get a few minor upgrades)

And now you'll have tons of fun hunting for tubes. It's a great entertainment but will certainly cost ya.

3rdRock - Please report back on this, I am very interested in this amp. I'd really like to know how it would synerguze with some GS1000's... Right now I am thinking of making my primary rig in the home office - Stello DA100>WA6>GS1000 or Denon D5k... very curious about synergy with this predicted set-up.

thats really impressive, how much are those v-caps?
post #36 of 187
They are around 55$ each and worth it.

I just want to start out by complaining about the additional $330.00 dollars this thread has cost me in up-grades to my WA6 amp that I originally ordered approx. 2 weeks ago. I'm certain once I receive the amp (with the up-grades) all will be forgiven though. Next on my list is selecting a couple of good Rectifier tubes... (lets see, only 2 weeks left!)

GZ32 and a metal base GZ34, that should do it.

I've been listening to a 5R4GY lately, and i think it gives the GZ32 a run for the money...it doesn't have the mid bloom thing going for it, but air-space, liquidity and head-room...it has plenty of...and they're relatively cheap at $15 a pop...and it's indirectly heated, unlike the 5U4G, so it's friendly to the triode tubes driving it...it may not suit bass-heads but if spaciousness and 3-d imaging is your thing, try a 5R4GY...it took about 10 hrs. for the sound signature to stabilize...

I'm curious to see if the amp specs (for the WA6) will change after the addition of the following 4 upgrades to an amp?

.15/600-TFTF(x2) V-cap .15u/600v

bg220u/200v(x2)Blackgate filter capacitors

bg150u/350v(x2)Blackgate decoupling capacitors

bg220u/16v(x4) Blackgate by-pass capacitors

Something for Jack to work on in all his spare time...

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!
