I was reading that the Treasure draws 50% more current than the typical 6SN7. As such I wonder whether our WA6SE transformer can withstand the additional requirement. Appreciate feedbacks. 

 
Found another article that stated the specification is the same as 6SN7GT and keeping my eye on a match pair Premium A ShuGuang Treasures CV181-Z http://cgi.ebay.com/matched-pair-Premium-ShuGuang-TREASURES-tube-CV181-Z-/320578800185?pt=LH_DefaultDomain_0&hash=item4aa3fc4a39#shId . 
 
The asking price is much higher than most of the NOS and wonder how will it perform on a WA6SE, and will it be overkill..?

 My order for a 1940's Ken Rad VT-231 is lost in transit as for now...

I think i can say this is a no brainer for anyone with a wa6 amp. The improvement is astonishing to these ears.
Let us know when your adapters arrive what you think.
And be sure to give the tubes a few hours...


Another happy convert.  :)  I could never go back to any tube in the 6DE7 family.  I would be completely unhappy with that sound now.  The wait for my Bad Boys is killing me, though it is starting to make me a little bit sad that this may be the end of the road so far as experimentation goes.  The TSR's are really the only other NOS tube that is regarded as highly.

You still have the 6F8G , 7AF7 , 7N7 , and 6CG7/6FQ7 to experiment with. The 6F8G round plate sounds the best to me
sounding as good or better than the TungSol round plate 6SN7s for much less money.

I've never really understood what game Shuguang is playing here.  A *real* CV181 is an ECC32, not an ECC33.  An ECC33 is directly equivalent to a 6SN7GT.  An ECC32 is *NOT*.  The ECC32/CV181 does indeed draw 50% more heater current than a 6SN7GT does.  So if the Shuggie "CV181" does not, then it's a 6SN7GT in a small ST bottle, and NOT a CV181, regardless of what the name says.

Agree with you here.

I would say that Beyers and Woos are a match made in heaven.  But, that's my opinion, and I'm biased.  I have a Woo and some Beyers.

Should have posted this here in the first place, but do you guys think my Woo Audio 6 would sound good with Beyerdynamics DT770 (600 ohm or 250 ohm)?

Perfect! So the Woo 6 would be able to drive the 600 ohm version more than adequately? I'm almost positive it can, but I just need to make sure.
