using 6FD7 and 596, great bass control, absolutely no harshness or distortion, and everything sounds great. finally headphones that don't seem to distort even with pop and rock music. maybe even better than T1. i'm not sure. 

 

but these definitely have TH-900, much better than the 10% improvement over D7k i mentioned earlier.

Hi guys.

 

I think I'm a bit late to the game, but here it is, WA6SE with the Princess and 6GL7 upgrade kit. I also swapped in a Furutech 3A Slow-Blow fuse for a good measure.

 

Here are some pics. ^^

 

The princess sure looks sexy at night!

 

They're just hangin' out.

 

The amp has just around 5Hrs on it, and to tell you the truth it's quite congested and uninvolved ATM. I hope that it will open up after the burn-in. FYI, I tried the demo unit at the store and I did love it (that was with stock tubes) so I hope this one will be better when everything is in place.

6gl7 can be muddy sounding with sophia especially with hd 650. try stock driver tubes and sophia.

also, burn in does help, my wa6se sounded pretty harsh at first

I have a pair of PS-1000 on loan from my local hi-fi dealer. These are not going back. The Woo just loves them. Much bigger soundstage than the HE-500, better extension in the bass n treble. Way more dynamic and detailed too. I would have been hesitant to buy these without trying them first.

That's also my combo in the 6 for the Grado/Beyer cans I have.  Solid!

Thanks for the suggestion. I tried swapping in the stock drive tubes as you suggested, and suddenly, it changed for the better. The sound was more open and there was better definition. I can't believe Woo even suggests this as the "ultimate" (well, most expensive) upgrade tube for their amp.

 

Seriously, is this tube any good? Initially I thought it's the best, being that it's the most expensive option, so I grabbed it together with the Princess. As it turned out, this option made the amp sound even worse than the cheap stock drive tubes.

 

BTW, what's the ultimate drive tube for this amp, especially for HD650, and possibly HD800. I tried the stock tubes (6EW7 & China 240B) with HD800 and hated it, too much sibilant.

6GL7 is pretty good. its best in terms of power, has the most gain, orthos like hifiman and audeze love it. its sound signature is dark with lots of bass and treble, kinda v shaped. it works well with bright tubes like 596, Mullard GZ34 (this combo might be way too bassy on some headphones), and some other tubes out there. 

 

however, the sophia has a sound signature thats kinda aggressive yet smooth and it has a full well extended yet slightly bloaty bass. so combined with 6GL7, it becomes a boomy muddy mess, especially with a dark headphone like HD 650. i much prefer stock 6EW7 or 6FD7 for them. the sophia is good  rectifier for them, as well as EML and 596.

 

6EW7 is pretty good, but only with sophia. with other tubes it becomes thin and bright. my number 1 favorite tube is the 6FD7 (and 6GL7 only with 596 rectifier). the  6FD7 is the most balanced drive tube available. has to be the sylvania one (the westinghouse fat bottle that jack sells is sylvania rebrand, so thats good as well).

 

for HD 650, almost anything works. except 6DR7, 6GL7, and maybe 6DE7. sophia is a great rectifier for the HD 650s, just check out the 6FD7. the 6EW7/Sophia combo is already one of my favorites though. the 6FD7 tightens up the bass and makes them more dynamic sounding.

 

my favorite combination for HD 800 would be 6FD7 and a really warm tubey tube like mullard GZ37 or Philips 5R4GY, or maybe 6DE7 with them for a warmer sound as well. lol hard to decide.

Can anyone tell me how much would the burn-in improve the amp's sonic quality?

 

The amp has now less than 10Hrs with the stock 6EW7s and the Princess, and the amps currently sounds terrible. Well, not that bad but very boring and very narrow dynamic range. Comparing with my DV332 (which is significantly cheaper), the DV332 is better in term of dynamic, smoothness and treble extension. Something must be wrong here, or the amp (together with the tubes) just needs some time to settle down?

 

Frankly, at the moment, apart from a beautiful look, I really don't get why the amp received all that hype.

 

In the manual it said the amp needs around 150Hrs to perform at its best. I presume it will be "that" great after that period, right?

post #837 of 1600

give it a while. i know i was kinda underwhelmed at first, but it did improve quite a bit.

post #838 of 1600

Until you've put at least 100-200 hours on it, don't consider it "broken in".

post #839 of 1600

What about the 6em7?

By far the most amazing headphones I heard at yesterday's meet.  Second was the TH600...

 

I wanted to hear the 900 so bad but no one had any...
