Review: Woo Audio WA6 vs. WA6SE (stock units) - Page 15

post #211 of 508
Yes, AFAIK RCA is the only available thin bottle 6ew7 which can fit into the narrower socket of the older WA6 amps.

I'm not sure how they sound compared to the fat bottle 6ew7 tubes, I hope to receive a pair of RCA 6ew7 in the next few days to try them out myself.

I just received both Tung Sol 6DE7 and Tung 5U4G/B.

Wow. Unbelievable.. I didn't expect this much improvements from my previous setup.

Halcron --> Tung Sol 5U4G ST (Man. This is major). Silk smooth.
Raytheon -> Tung Sun 6DE7 (Wow)

Wow.. Just wow. This is what you guys meant by "Tubey" sound...

I just got a pair of thin bottle RCA 6EW7 and they sound better in my WA6SE than the GE fat bottle 6EW7, and perhaps a little better than the Sylvania 6DE7 too. They give me the better bass of the 6DE7 with the better spaciousness of the 6EW7.

Jeez Thanks, not only am I on the look out for 5998s, 6SL7s, 6SN7s, VT-229, VT231, I have to add the 'thin' 6EW7s too

Thanks for the feedback sclamb, sounds promising

Yeah! I didn't factor in the tube addiciton when I got the WA6 I now have a BIG box just for all the tubes I find myself buying.

I have to find some of those RCA 6DE7s from the 1950s now

Interesting! What was your previous set-up on the WA6?

OK, forget that. I just re-read your post and saw the previous set-up

Interesting to see if there is a rectifier that tops the Sophia Princess at a more affordable price. The best I have found so far is the Mullard GZ30 brown base, although is doesn't better the Sophia.

Do you mean...

... you got a Tung Sol 5U4GB... or... a Tung Sol 5U4G ST... or... both???

If both... do you mean... the Tung Sol 5U4GB is better than the Tung Sol 5U4G ST???

Interesting. I am also curious about which rectifier you like.

It's great when you find that combination that changes the sound for the better. It's a wonderful feeling... until the next day when you start to mull over the possibility that there is something different out there that would improve it again.

I listened to my rig last night, and I was blown away by how good it sounded. All of my tubes are burned in, and so are the phones. The sound was so open I could swear I was listening to electrostats. However, the deep and powerful bass out of the Denons proved otherwise.

For the record, my current tube combo is:
- Sophia Princess
- 1960 RCA 6DE7's with shield
- 1953 WE JW-2C51-396A (in my DAC)
post #221 of 508
I'm leaning towards getting a WA6SE for my RS1s but I'd like to keep the cost down if possible. The tubes upgrade isn't so hefty but is the premium parts upgrade package worth the cost? I'm new to tube amps and am trying to learn what I can from this great, albeit, expensive forum.

Another dumb question, does Woo include the PSU umbilical cord with the 6SE?
post #222 of 508
It includes the umbilical but not the power cord. I think the biggest upgrade would be the tubes.
post #223 of 508
Tubes first. The max'ed out WA6 SE sounds like a crap with stock 5U4G compared with Sophia Princess 274B mesh plate.
post #224 of 508
Capacitors and resistors have come a long way. Even fairly inexpensive but well made from good manufactures are way ahead of past caps. I would focus on the tubes and enjoy the amp.

Ok, sounds good. Thanks people.
