SET Shootout China VS The USA


2A3 SET from china arrives any day now.

The tech who loaned me his UX250 (aka 50 Tube) amp, with a  12AU7 in front + a  6BH7 (??) , has incredible pure Cobalt out trans. ($1k+ each back in 2000, now no longer in production). . he will help me set up the  2A3. 

Has a  AX+AU my 2 fav front tubes anda   quad of 2A3's. 

My speakers are pure neutrality, no coloration, no distortion,. 

So whatever amp/ source you plug in, will register the nuances inherent in the circuit.

Will be very interesting. 

USA has pure cobalt out trans which gives the edge in power, but the china 2A3 has a 2 tubes per channel.

Gonna be interesting and will post a  YT upload with comments,

AFTER TESTING IS COMPLETEED.

Hand on to your horses at the OK Corral. 

Grab a  beer at the saloon, 

sundown shootout at the edge of town.

I really enjoy this thread. Been introduced about many tubes that I have not known existed before and learned things about those familiar with. Compared to many herein I have limited experience with tube amplification having introduced myself to them in my own system only in the decade. Currently I am using a 6SN7 based preamp with a 6SN7 tube driven PP amplifier which takes several KT variants and EL34s. 

Must say this thread reafirms my amazement at how one can so easily become profoundly adamant about their position on a subject that is so subjective in nature. Like for example how something sounds.

I loved the saying brought forth by ghasley  ...credibility wanes as your hyperbole rises as you discuss the absolute of your beliefs...  Quite generally apropo with the replacement of 'you' with 'one'.

WEll as far as Chineswe 2A3’s vs NOS RCA ’s. For the record AT LEAST TO MY EARS, The stock $30 chepo Psvane’s wopped the **LEGENDAY* RCA NOS double plate 2A3’s. But you can read and believe what you wish. IMHO the new prod chinese 2A3’s and most likely 300B’s are far superior in NOS RCA’s(= over rated). Just thought I’d set the record straight. Who wants smudgy midrange? The Q we need to answer is rating the 2A3 C vs Z vs T vs E Lin Lai versions. btw I think Shu black glass T series = LL black glass T series, same exact tube. Shu is making tubes for both Psvane and LL. Same as in russia, New Sensor makes tubes for Tung Sol, EH, Gold Lion, etc. However they are not the exact same tube. Gold Lions do not sound like Svets and EH’s. Each 88 from russia sound different. But in chinese tubes, the differences are more miniscule. Psvane ACME 2A3 at $1k a pair will sound almost exact as LL’s E series 2A3 for $500 a pair. AS both are made in Shu’s plant. Same materials. BUt in russia the nuances are more significant between each brand. Same plant, but wider range of details in the design.

I believe that Shuguang and Psvane are two seperate entities with their own seperate manufacturing facilities. Psvane initially derived from Shuguang but is today independent .
