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.

If the idea is that one should not buy products from a country that ranks lower than one's own, based on whatever social metric, this would be problematic for those countries that rank high.  You could scarcely buy anything non-domestic if you lived in Denmark or Finland, for example, but the world is your oyster if you lived in Nigeria or Myanmar.  

I take it you have a 12AT7 LTP @ +-300V with something like a cascode 10M45S CCS below?

@pesky_wabbit Yes, something very similar to that although the CCS is our own design. There's a 'steering diode' so the cathode voltage can't fall below -0.7 Volts; this protects the tube from developing cathode/filament shorts during warmup.

well my dream  of owning this amp via my selling the Defy, , I just canceled the Defy 7 ad , all for 3 hours,, had 50 hits,,, ad canceled, after i RE-visited the KU 307,, I did not let vid finsih BEFORE,, so i just went back and Beethoven was playing,,, hummm, SET's are #1 for jazz, blues, light chamber,,, sym orch,, forget it. 

DHT PP will respond to full orch, but NOT their lil brother the Single DHT. 

Defy ad canceled.

Going with a  3rd amp the 300B PP, contary to my techs advice to stay away from anything *300B*.

 

You shouldnt make decisions, audio or political, based on youtube videos. Also, just because your tech can fix something or tell you how it works doesnt mean he has earned the right to hear for you too. Buy what you want to buy....

@laoman Then go find a forum like this in the PRC. Where you can speak your mind for the most part and not have to worry about having your front door kicked in.

Why are you supporting China's economy?" Be aware that not all posters on this site hail from the US. Some of us would rather support Chinese technology rather than US technology for various reasons including political,

Interesting comment from someone who clearly has no idea of the political landscape, eh Jerry?
