My WA22 high gain / low gain doesn't seem to work.

If I have the volume set half way playing music and I switch from high to low should there be a difference in volume?

On mine it is exactly the same level.

it's an output impedance switch not a gain selector

Okay. Whew. I'm new to my Woo. I was getting worried. I didn't want it repaired all ready.

So my headphones are Audeze LCD 3's pre fazor. Do I put on high or low?

 

[roskodan]

up your preference which sound better to you

(apologies for wandering a little off topic in this reply).
 
I just did some mental maths on how many WA22 amps I could buy for what I have spent on 300B tubes for my WA5. The answer is close to '2'.
 
I love the sound of the WA5, but high end 300Bs are bat****crazy expensive.

Yeah, guess the term Budget 300B is an oxymoron

  Are you saying you have 16 pairs Sylvania 6SN7WGTA's, and you paid $60.00 for them?
 

 
What i meant was the above combination in the pic cost me $ 60 & gives decent sound. I have a pair of Sylvania 6SN7WGTA's coming in for which I paid $ 16. I will substitute the Sylv's for the TS in the above combination & If I still get similar decent sound then the  cost of a tube combo which gives decent sound on the WA22 will fall from $ 60 to $ 46.

Badas,
 
Typically HP's with impedance of 300 ohm & above (HP's like Senn HD 600 / 650 / 700 / 800, Beyer T90 / T1) are meant to give better sound with high impd setting. Whereas HP with impd lower than that (Audeze's , TH 600 / 900 ) will sound better with low impd setting. But this is not a hard & fast rule try both & see which one you like.
 
With my XC / TH 900 the the HP's become very loud with only a small turn of the dial on High impd setting & I get very little play with the volume control hence I prefer using the low impd setting. Sound is similar on both settings IMO for the XC / TH 900.

so it is a gain selector? not a output impedance setting?

It is supposed to be an Impedance matching switch (to the best of my knowledge) but strangely acts as a Gain selector for some low impd HP's (i.e SQ is similar in both settings but gain level differs). I have not tried High impd HP's on low impd setting. Will try my HD 800 & T1 on both settings today & report back.

 

[roskodan]

np, guess there will be a slightly difference in power, more noticeable with high sensitivity cans, just wanted to know about the function since woo audio is pretty vague about its specification, and i'm quite curious what the actual values are?

 

[Badas]

I've just conducted a big test. I found low had a very slight edge. Soundstage was a tad more realistic, just slightly mellowed any tiny bit less harsh. No difference in volume using Audeze.

System is still too bright for my taste. I have the RCA smoked glass drivers coming soon. I hope that rolls the treble a bit. Starting to think that the Oppo HA-1 is the issue tho. Might have to change the DAC.

Will the treble change much with age? All my tubes are very young. Less than 10 hours.

I get a significant increase in volume between the low and high settings with my HD800's.

 

[roskodan]

well i guess the difference between low and high Z out levels vary substantially with different tubes

Hello
I have a Wa6 like the picture ( above ) and i would like to modify it  like this :
 

 
Does someone has a shema with the modifications ?
 
Thank you

 
Serge

 

[roskodan]

woo audio made such upgrades in the past (or was it just for the wa6-se?) so you should drop them an email, and report back

What tubes are you currently using ? Some of my tubes had sharp treble which disappeared out after about 70-100 hrs of burn in.

If you don't mind me asking, where did you pick up Sylvania 6SN7WGTA's for $16.00???
I've paid quite a bit more for the 6SN7's I have, and would be very interested in more at this price.
Thanks
