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.

Neither sounds particularly good. I think that is supposed to be piano playing at about the 8 to 9 minute mark of the first video. It is pretty tough to tell for sure though. Bright and splashy with overall poor timbre. The Sonus Faber have a somewhat more realistic piano, but is closed in and dark sounding. If I am forced to choose between them, it would be the Sonus Faber but only because it is less bad.

IMO its a tell of the sorry state of affairs in high end audio that there are SETs that actually do sound better than their PP brethren- it really shouldn’t be that way!

For a number of listeners this is their conclusion. You give rationale explanation as to how push pull topology could easily equal (Or surpass) the sonic presentation of a good SET amplifier. Problem is very few manufacturers commercially are following the recipe you propose.

Most happy SET owners migrated from the world of transistor and push pull tube amplifiers. Very rarely is SET the first amplifier choice for newbies. Rather it’s a choice discovered after ownership and exposure to non SET amplifiers. So most of these converts are seasoned listeners and owners of High End audio components.

 

Upon introduction to a good DHT SET some listeners find a purity, aliveness, transparency and most importantly a genuine deep emotional connection with their music listening experience. These traits were found lacking to some degree with their previous non SET amplifiers. Some do return at some point to other amplifier types, but many do not. So perhaps other manufacturers should heed your guide lines for improving their push pull amplifiers.

The Sonus Faber version sounds better but it's impossible to know if it's the system or the quality of the recording. Neither sounds great but that's YT for you.
