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.

@charles1dad @larryi and @alexberger well said all around on tubes and the Japanese influence on audio. And @pesky_wabbit what amp are you running? @mozartfan you're getting tons of great info and advice on this thread but you need to start listening to actual amps and not youtube. You seem to have a good tech maybe you could commission him to build you an amp or two using these tube types that fascinate you? |
well what we are all finding out is that there are such amplifiers as
~~~DHT PUsh Pull~~~ Ner heard such a design. All I knew about is SETSETSET. A SET on a xover type speaker does not work, I tried it, its a complete failure. Either high end horn or FR (or Concentric if that floats your boat, Tannoy. My next experiement is to find out if the KT88 ,,,lets say, how dif in nuances /midrange is the voicing on a KT88 vs a KT90. This is my next experiement. I'm holding out hope for my PP amp. What can a KT90 offer paired up witha dual FR. The 88's were just a bit too midrange heavy to work with dual FR. Its like midrange X's 3. From what I remember of the EI90's in the JOR, there was magic in the soundstage. = more recessed midrange. I think everyine goes for the 88's as their xover/low sens speakers needs all the voice they can get in midrange.
This is why they choose 88's. The 90 has been completely totally thrown under the bus. Google kt90 on audiogon,,, haha, maybe 5 posts on that tube past 10 years. vs 88's, 100's of posts. Its all which 88 is best. Audiokarma, DIY, all sites, 888888888888. If I can sell my cayin cd17 I can get the 90 tubes,,,no bites 3 days,,,,,, priced rock bottom w mundorfs.

Perhaps in your one instance, the complete opposite experience for me. My 3 way 5 driver speakers were built from the ground up to be very compatible with SET amplifiers. Same brand (Coincident) built by the same person (Israel Blume). Granted the crossover is a minimalist 1st order design (One tweeter capacitor). I'm referring to the Coincident Total Eclipse II, 94 db sensitivity and a 14 ohm impedance load. It pairs exceedingly well with the Frankenstein MK II 300b SET mono blocks. 8 watts of pure music listening joy. It replaced my very good 100 watt mono blocks (6550 or KT 88). So once again it most definitely depends on what specific amplifier (All 300bs aren't created equally) and what specific multi driver speaker (They aren't all the same). This is my sublime experience the past 12 years. Charles |
