Emission Labs 300B vs Shuguang Black Treasure


Hi All,
I want to upgrade the 300B tubes on my Wavac EC-300B amp. At the moment I am still using the stock tubes which are a pair of standard Shuguang 300B-98. I did try out a Shuguang trasure tube some time back. It made for an over all richer sounding tones and slightly lower noise floor. However I am more intrigued by the emission Labs standard 300B solid plate tubes. They seem to be built better and claim to have lower distortion too. Can some one help me with the sonic signature of the Emission labs 300b vs Shuguang treasure ? I also thought of considering the Sophia Mesh or Carbon tubes but I am a bit skeptical about their reliability.

If your friend was in US I could test his tubes with my Amplitrex tube tester for free.
Pani;
i have exactly the same dilemma. i currently own the black bottles (2yrs), and wonder if i should continue with them(now the psane's), or buy emission. The emissions themselves present another so called dilemma, their regular 300b, or the xls version.
i have been happy so far with the shuguang-z's, however i dont know if the psvanes will be the same, better, or worse.
Trouble is that, and the emissions are about double the cost.

Audio nirvana is so difficult to reach ;) !
Rlowe ,
I used the Shuguang BT very happily for 2 1/2 years, supposedly the Psvane Black glass is a bit better. I can tell you that with my amp the EML XLS is the better sounding 300b. It's worth the cost IMO, keep in mind that these are high quality long lasting tubes. You'll get your money's worth.
Charles,
I am happy with both my Psvane and Sophia Mesh 300b but planning to get the EML300bXLS as a Christmas present for myself :) My Stancor 300b trannies are capable of a 3mA draw which is more than enough to handle the demands of the EML tube.
