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.

Discovery and exploration is fun.😊

Another 8 series tube is the 805. An accessible and affordable example is the Line Magnetic 805ia/ 508ia which 48 watts of pure class A SET. Those who have heard or owned it say it’s wonderful sounding. Some SET afficianos make the point that the lower power SET amplifiers are more intimate, nuanced, tactile and pure in their presentation.

Obviously opinions and taste vary as with anything and it simply becomes a matter of what one is seeking. The higher power SET amplifiers certainly allow for greater speaker choice flexibility. Always some degree of tradeoffs, so just depends on the objectives of a given listener.

ower power SET amplifiers are more intimate, nuanced, tactile and pure in their presentation. ~~~~~~~~~~~~~~~~~~~~~~~~~ huummmm I know you mentioned this trade off somewhere else, maybe on this topic.. hummm, looking at adding a 2nd SET or a DHT PP Both lower end amps, under $1600 300B/PP has Pre IN so I can use the Jadis DPL the other 845 w 2A3 as drivers/pure amp w a cd jack/amp has vol knob. Everyone says they love their 845, ,,, but as you say might have to give up up some nuances offered in the #00BPP..... can't ask Richard for advice, he's not going to give thumbs up on either....another amp buy, behind his back. I'm probably going 845 as i already have the 2A3 PP.

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'.
