I'm considering WA7d + WA7tp for my Sennheiser HD700, however it would be nice to try it before ordering. Do you know any place / shop in Hong Kong where I can try it?

Hi guys, I recently picked up the Electro Harmonix tubes and it causes a hissing (that is audible when music isn't playing) which the Sovteks didn't have. The stock tubes are dead silent meanwhile. Does this eventually dissapear or are the tubes faulty?

WA7 is a headphone amplifier, not recommended to drive speakers.  You can however use WA7 as a DAC via the RCA output to a powered speaker.  This output is a Fixed Line Out so the volume control is handled by the powered speakers.

 
I just picked up a demo unit from Audio Advisors. To use as a DAC, can I run the rca out into my integrated amp (aux input) to drive my speakers? I didn't see what the output spec was over rca. I don't want to damage my integrated amp (Peachtree Nova 125).

Sure sounds like a bad tube (noisy) to me did you get them from woo ? if so send them an email maybe you can get another pair..

You would be able to use the wa7 that way to drive your speakers..

Yeah sent back the tubes, hopefully I'll get some new ones

WA7 out to AUX input is ok for D/A mode.

  @HiFiGuy528, heya mike! how are you doing? just curious what gain setting on the WA7 do you think is appropriate for the upcoming Ether and HE1k? also curious what gain setting you normally use with the HE-560/LCD-X/K7xx. thanks!

 
technically Low setting, but which ever sounds best for you.  It won't harm the amp or the hps on either setting.

Any body thinking about updating umbilical cord? I found that Revelation Audio Labs makes some that will work on this. I am seriously thinking of doing the update, especially seeing how tube changes in the power supply have such a nice effect.

Just ordered a Passage Cryo-Silver 1/2 meter length.

I didn't  think of that upgrade, cool post a pic when you receive your cable..

Will do, not sure how long it takes to make. But I will try to share what it does for the sound as well. I am stoked! I am using a Triode Wire Labs power cord and it just seems wrong to have a cheap umbilical cord in between.

 

[abvolt]

I agree that make good sense, I also believe a good power cable makes a big difference in sq..   

 

[mjock3]

Going to be a bit before I get the cable, hit a snag in the road. I just got a small power cord from RAL for the power wire from supply to my Mac Mini and all I can say is WOW. When I get the one for the Woo I will post pics.

 

[abvolt]

I just looked at those cables now I see why you hit a snag wow there pricey, the 2 meter power cable costs more then my wa7d/tp, that will always be out of my price league Lol..

 

[mjock3]

No actually the umbilical cord is reasonably priced. Ran into a snag because of the connector Woo Audio decided to use for the umbilical. I know some of RAL's cables are way out of my price range, however the ones I am talking about are not. And if the small one I am now using between my power supply and Mac Mini is any indication I think this is an outstanding upgrade for the dollar. Can't wait to get it.
