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.

assuming one’s system sufficiently resolving ~~~~~~~~~~~~~~~~~~~~~~~~~~ Someone etch this in stone./ The other day I swqaped out the jadis JS2 DAC for the wonderful wounding Shanling 300 cd player (which i use as a disc drive for the Jadis)), and man, as good as the Shanling sounds, theJadis DAC with Teles/Mundorf caps, JFET class A opamps, was superior.

That aside, if one has smudgy, colored speakers,, it makes no sense whatsoever to invest in high priced 2A3 tubes.

Compltete waste of money.

My speakers are higher sens,  and clearly register any tube roll.

. As you say, Shugang has liscened out its facilities to Psvane and Lin Lai to make their tubes INSIDE Shugaung’s manufacturing tool shop. I prefer LinLai as they actually give a few words why they want $250/pair for the D series and why they want $500 for the E series. I will probably go the extra cost and get the E, as they will out last the Ti coated Dream *D* series, stronger plates = longer life + less chance at a failure. + tiny nuance superior sonics. . My tech completely disagrees/dismisses this theorum, as **baloney**

FWIW the Shugang plant that made their 6SN7s burned to the ground about 2 1/2 years ago (so that tube has gotten hard to get). I've heard they are rebuilding. But somehow the Psvane and LinLai 6SN7s are readily available so I don't think the statement above is entirely correct .

I believe it was Stereophile or some other online review that madea shootout of LinLai top 845 vs Psvane ACME, even draw. Priced same.

And yes SET folks never ever go back and purcahse a KT series amp. If we add a 3rd amp it will be another SET type.

Although we all have a KT amp in our collection, our crown jewel is the DHT's.

. Runner up is our KT series amp, WE still need the KT’s for big orchestra and complex heavy jazz, especially if we want a lil more SPL. But our pride and joy is our SET’s.

I have heard many good SET amps, OTL amps and pushpull tetrode/pentode amps (what mozartfan refers to as KT amps).  For the record, I’ve gone from a very good SET amp (Audio Note Kageki) to a pushpull 349 amp.  It is simply not the case that one never goes back from SET amps.  There are no absolutes.  I don’t understand what appears to be a compulsion to declare one thing the best.
