Congrats!  You'll love it.  I look forward to listening to mine every night.

I've just collected my Woo3 from the parcelforce depot. It's bigger and heavier than expected, it looks so tiny in the pictures!

I'm using the stock tubes, driving the HD650. My source is the Valab nos dac, cables by Cardas.

Now burn-in time :-)

Looking forward to your impressions.  That's a really nice rig, it should bring out the best on the WA3

I spent a few hours listening some well known recordings to understand the difference with the Earmax. The Woo sounds more transparent, clear, while the Earmax is thicker, softer. The Woo clearly has more power and better dynamics, but the midrange of the Earmax is simply magic, liquid. On acoustic jazz or chamber music the Earmax is more intimate and involving, but with symphonic music the Woo can deliver better soundstage, imaging and instruments separation. All in all I wouldn't call the Woo 3 a warm amp, at least with the stock configuration. The Woo also has a noticeable hum, quite annoying on solo piano pieces or between songs. I sent mr. Woo an email about that, hopefully burn in or tube rolling can fix it.

Quick update on the sound: I usually listen to very low volume level, but yesterday I tried to increase it.

The pot was at 9.30, and really the sounds became sweet, with better bass definition and body.

I was listening to a piano quinte (Dvorak, played by Richter) and at the usual volume was flat and boring, actually I was reading and surfing the internet and not listening to the music. But as soon as I raised the volume...bingo!

Mr. Woo replied to my email about the hum: I'll try to unplug everything (dac, laptop) and different outlets.

Yeah there seems to be certain amps and headphones that need to be turned up louder than others to get the best from them. Glad you seem to be enjoying your Woo! Look forward to further impressions.

Hum with a brand new WA3 is most likely caused by the stock 6AS7GA tube. Get a 5998 instead. Maybe you would like to read through some passages at the beginning of this thread, where my experience with a brandnew WA3 is described (hence the name "WOO Audio 3+ experience )  - you will find some info on "smooth sound" as well. Good luck and have fun with it.

You're right MooBin!

Just noticed you got the same issue with your stock power tube.

I was planning to get the Tungsol 5998 soon, I'll probably get it sooner :-)

Everybody seems to agree about the 5998, abut I can't find it here in Europe. Anyone can suggest a reliable online store?

Thanks

I quote myself 

What about this and this?

What's the difference between these two versions of the 5998?

The EBay seller "TejasTubes" is a reliable seller and I have gotten some very nice tubes from him.  And these days, $50 per tube for 5998's is about the going rate.

Thanks Skylab! 

I just bought them...hopefully swapping the tube will fix the hum as well.

A quick update on my Woo3 experience.

The amp is sounding better better, even with stock tubes. I'm waiting the Tung Sol 5998, but I'm actually very happy with what I've got now.

 

Two things strike me most: transparency and dynamics. 

The Woo is very clear, with good highs extension, without being bright.

Great coherency through the frequencies, and, at least in my configuration and to my ears, not as dark and warm as many suggest.

And then, dynamics, dynamics, dynamics....the difference with my previous setup is so obvious with symphonic music. Have I said already that dynamics are so good?? 

Soundstage is not huge, but still credibly and realistic.

I have to report also a good synergy with the Valab nos dac: the combo so far doesn't sound too smooth, muddy or dark

 

Overall this amp makes you want to listen to music, and not to gears. It doesn't hide any detail, maybe they're just not in your face.

My current setup (a fanless Dell Mini with Linux, Valab, Woo3 and HD650) costs a third (or probably less) of the previous one (Mac mini + Pure Music, Halide Bridge, Audio-GD Ref.5, Audio-GD Roc, HE-5LE), but I have no regrets.

I'm not saying it sounds better (that was a terrific rig), I'm just saying it sounds the way I like it, I'm listening to a lot of music I completely forgot of and I have some money for buying new music (and tubes!)

post #103 of 190

Great to see your enjoying your purchase!

post #104 of 190

I received some new tubes for the Woo3: a 6AS7G RCA and a pair of Amperex ECC88.

 

Unfortunately the hum is still there, I'd say louder than the stock tubes, and it gets louder after a hour or so.

It comes mostly from the right channel.

 

The Amperex are very very clear, too clear for me, almost bright, but they will obviously need some burn-in.

On the other hand, the 6AS7G RCA is just superb: liquid midrange, a bit forward, with 3-D instruments.

post #105 of 190

Out of 4 RCA 6AS7G tubes I tried, three of them hummed.  I sold two to a buyer (one with a hum and one without) with the claim that one of that one of them hummed.  Both did not hum in his Darkvoice amp.  For some reason, Woo amps are very fickle with their tubes.  Some will hum in them for no apparent reason other than tube voodoo.
