The Woo Audio 2

I think you're going to be happy with the Bugle Boys. I just got a pair and they are fantastic.

People may also want to try the SQ version of the Philips 6922 - got a pair for my WA2 a couple of weeks back and I am liking them a lot - leagues above the normal Philips 6922s that ship with the amp. They do a 7308 version too, but those are more expensive.

Anyone tried 6922s or 7308s from Telefunken or Siemens in the WA2? I hear good things about them in general, but they tend to go for a lot of money even used so it'd be nice to have a first hand opinion from a WA2 owner before buying.

Ok, I received my 6dj8 (2 smalll and 2 large "o getter", white printing) and tried these last night. And indeed, it flats down the bump I had and turn the sound into something really more enjoyable. I also noticed it almost eliminates the noise I had on some records. Funny comparison but it really makes the same effect as did the dolby on our good old tapes

But I must say that swithing to the buggle boy didn't make a HUGE difference. Nothing striking here. I really had to pay attention to notice these differences. Changing the power tubes may make a more obvious improvement. But for now i must say I'm really happy with my rig, especially since I put my K701 on an intensive break-in. It now has bass !
Listening to "one dove" from Antony and the Johnson was something I never had experienced before. A complete immersion into realistic sound. But unfortunately, I don't find my combo forgiving... quite the opposite actually, and it's really not all my records which sounds that good.

I ordered a silver WA2 this week. Jack said four weeks for delivery, I'm thinking five. In the mean time I still have my 3+.

 

[LeMat]

A chance you have the 3+... otherwise, the wait would have been long !
Did you order the standard or the maxxed version ?

Standard...........it's the economy you know.

I had a quick question regarding the power tubes in the WA2 - do these need to have balanced triodes? Or more to the point, would two power tubes which are matched but may have unbalanced triode sections cause hum?

The reason I ask is that I previously bought a pair of Tung Sol 5998's which caused loud hum in both channels. I thought the tubes were defective but the seller insisted they were NOS and tested perfectly on their tester (very good feedback, reputable seller).

I recently bought a pair of NOS, matched 6N13S tubes and these too cause a major hum in both channels. There are no sparks or other issue; tubes look perfect; glow normally; and these too were said to test 100% on the seller's Hickok tester.

What they said was that if the triode sections of these power tubes (6080, 6N13S, 6AS7G etc.) are not matched/balanced it could cause this problem?

My gut feeling (nontechnical) is that I don't think that mismatched tubes would cause loud hum. The reason I say this is that one of my nice Tung Sol's died so I am temporarily using two very cheap RCA tubes that are entirely unmatched (I bought the pair off e-bay for $5, completely untested). They do not hum at all.

How does this do with low impedance cans? Mainly, the W5000? I am having the hardest time deciding between this and the Woo 6 SE.

sixerfan - Haven't tried with W5000 but the WA2 controls the Denon cans VERY well. I've tried LA7000, LA2000 and the stock Denon cans, all to satisfaction. It might seem counterintuitive that a tube amp - one without transformers, no less - can handle such low-impedance phones, but that's what it does for a fact.

The W5000's impedance is 40 ohms, which is not as low as some. My understanding is that the WA2's output impedance is approximately 60 ohms, so I think it should be fine. People have reported excellent results with the WA2 and GS1000s, which is only 32 ohms.

I vote for the WA2 over the WA6E, but I own a WA2 so take it with a grain of salt...

Great, because Jack has suggested the 2 for my preferences but I have read so many good things about both. It's very hard to decide.

I'm in the EXACT same boat as you.

 

[moonboy403]

I'm also emailed Jack asking if he can make a WA2 that's in glossy piano black.

You guys should be thinking about a WA22 now. Balanced, yum.

I needed speaker out as well (for Stax transformer and K1000), so it was between a Beta 22 or a Eddie Current ZDT. Tubes won...
