Woo Audio Amp Owner Unite - Page 1829

post #27421 of 30571
Hi All,

So i have my pre-owned LCD 2.2 and Woo Audio WA6-SE set up today. The rectifier is the cheap Chineese 274B tube. The driver tubes are the 6FD7 tubes. I like what I hear overall but I have to say the treble is a bit analytical and the lower frequencies don't seem to have the control they need.

What direction tube wise you point me? I have to assume the rectifier is the culprit for much of what I am hearing. It could also be that I need to give my ears a chance to adjust the LCDs...I have not ruled that out either.

Thanks!

try 6GL7 and 6DR7. maybe even 6EW7, play around. the 6EW7 is smooth and wide, but leaner on the bass, the 6DE7 is warm and tubey, the 6DR7 is very wide, 3d, and euphonic, but has weak bass, the 6GL7 is U shaped, but tons of power PRaT and dynamics, the 6FD7 is very well balanced, neutral almost but with a bit of tubeness, probably the best tube for the LCD-2.

 

like i said, you should look to upgrade the Shuguang 274b, its a 7$ stock tube, it tends to be bright and congested. not very musical (some people who have auditioned stock WA6-SE have believed it to be a bad amp cause this tube sucks, its a stock tube though, and its only purpose is to test if the amp works).  the LCD-2s shouldn't have any bit of analytical treble, especially with the WA6-SE. there should be none of it. a $30 sylvania 5U4G should be a huge upgrade already, and of course the 596 or a Sophia princess are great options.

Anybody know about the RTC 5R4GYS

 

It's claimed to be synonym to the Brimar RTC 5R4GY

Never heard of it. If u have, check the sound out, the brimar is very tubey and laid back, but transparent

For what it's worth, RTC was a French Philips group brand and manufacturer.

RTC tubes are excellent. I have used various different tyoes through the years and they were always good. I used the smaller tubes for my CAT sl1MK11 preamp for years. Boy do i miss that preamp

Hi All,

I changed the input source over to my SACD and PS Audio DAC and the Woo really shined. I should not have tried it with my cheapo dac. I guess the learning is that both the headphones and WA6-SE scale really well with sources. The analytic high frequencies dissapated and what I was left with was a pleasure to listen too...not to mention the whole package got a lot more holographic. Now I really cannot wait to get the upgraded rectifier.

Anyway, here is a picture of all the kids playing nice together...I am a proud father smily_headphones1.gif

Love your Revel, I have the Performa line for home theater. WA6SE scales very well, I have tried few dac before settling down with PWD.

Quite possible the last pictures of Miss WA22...  :mad:   Can't think of it right now, wish I can afford to keep both Miss WA22 and the mistress.

Except, her departure will aid your future audio development. Keeping her could very well hold you back from discovering the head-fier you're destined to become. :wink:
