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.

~~~~~~~~~~~~~ Hey Jerry did you note Qualiton’s 833 tube SET and their new 813 SET amps?? wowo, off the charts unreal. wow https://www.atelier13-usa.com/tube-amps-by-power-tube

 

 

 

Mozart FYI there is such a thing as a parallel SET amp using two, or more, tubes per channel perhaps that's what your amp is? ~~~~~~~~~~~~~~~~~~~~ Yes my tech is trying to explain what to expect. He mentions that my Jadis DPL linestage is SET, and the pre section of the Defy is SET, then out [ut stage on the Defy is PP. so then, there is no such thing as pure SET circuit, neither pure PP circuit. That a PP does have linearity midrange and a SET also can emply dual tubes to become a PP circuit... huh?? well we learn something new every day in this hobby. Tech was saying the other day, I might not like the 2A3 as its only 3.5 watts. Now if we see this amp is a PP circuit this bumps up the wattage to 10 watts per tube on a self bias AB1 circuit. Auto bias says 15 watts, self bias 10 watts..??why?? Got to go over with tech on that one. Or maybe not,,,,,we are going into rocket science now,, haha

@nonoise Not a Hamilton fan and I like seeing Toto lose. It's done and the new Senna, Prost era has begun. Max and Lewis will give us a great season next year, I hope.

Also hoping that the boys in Maranello can get their stuff together.

Cheers.

Sure transformers are important but just as important are quality chokes,

and internal parts like quality capacitors,resistors, wiring,connectors even tube sockets Teflon copper are the best , and many other things.

unscrew the bottom let’s see what’s inside , I have had upgrades to tube gear many times ,most use cheap parts unless spending well over $5 k 

I don’t see any mention of the cost ?

Why, oh why am I doing this...

MF, I just watched your linked latest video where you cue up the oft paraded before the peanut gallery Sophie Milman disc. After 5 seconds of play, you immediately declare that the bass is all there. What bass? This is a typical jazz combo with single female vocalist...probably the LEAST challenging genre (for top to bottom freq. resp.) of anything out there. It would be much more revealing if you hauled something out your mythical classical music vault and slapped that into the transport if you want to demonstrate to the handful of us following this train wreck of a thread the full range capabilities of the DL drivers.

And BTW, I think you confuse percussion with bass. Every time you hear a tom or any kind of drum, no matter what the frequency, you conflate it with bass. There was no real "bass" at the beginning of that Milman cut...maybe some upper mid bass at best. That whole presentation had a decidedly midrange centric quality to it and until you see fit to play something with full range content, you'll never really know what the DL shortcomings are.

SET and FR drivers at their current state of the art, will never be the choice for audiophiles who favor low bass content music like pipe organ, EDM, techno, synth, etc. because they cannot pass muster. Yeah, I know, you're a CM man (though we have no evidence of this) so maybe you're fine with rolled off extremities but your tastes, sir, inhabit the minority.
