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.
@larryi Funny you mention hyper realistic with the 2a3. When I was running 2a3 monoblocks with Omegas I often thought about this particular characteristic of internal luminescence. Mids had the sense of being lit up from within, very unusual, never heard this prior or since.
@mozartfan While its good to be excited, your credibility is seriously lacking. I mentioned it prior, all topologies, systems, equipment may move someone. This is all subjective evaluation, you come across as being objective when using extreme adjectives such as best, greatest, only, etc.
Saying particular tubes always sound a particular way is simply not true. As others have mentioned previously, so many variables to account for.
Your 2a3 tubes in your particular amp in your particular system really say nothing to us. |

WOW now thats a amplifier. 2A3 monos. Unreal.
Agree, the KT series ain’t no slouch , as i’m listening to sym via the 2A3, the KT88’s deliver a similiar result. We are only talking slight shades of nuances here. But over all, for my preference in soundstage, I prefer the 2A3 PP with a FR speaker. Low watt amp always works superior with FR vs a KT PP. Its my personal preference , maybe not yours. But as you guys know , I’m done with xover low sens speakers. And I know darn well none of you are about to follow my lead. FR are superior. For so so many reasons. call me Philistine all you want. I am The Iconoclast.
and yes I did correct Yaqin sp in the YT uploads. |
@mozartfan Just so you know, that 5% figure is for the tube alone; it does not include the rest of the circuit of an SET. The distortion of that at full power is more like 10%. If you really want to hear what almost any SET does, you need a speaker that makes no demands of the amp over about 20% of full power, so as to avoid higher ordered harmonic generation. Of that means a speaker that is more efficient than any 'full range' speaker can be- for a 2A3 no if ands or buts you need horns. At least if you want to produce realistic sound pressure. |
@ Atmasphere
Yes my tech Richard, just wrote to say 5% as vol gain goes up more distortion,, that 5% goes down as vol gain goes down. I listen at ridiculously low SPL levels, so for me this 5% is no big deal. well yes at full blast evena KT88 will show distortion. My tech and Charles among others wish that I retarct some of my strong opinions, as if to say **the 2A3 PP is just 1 of many options, 1 circuit is not superior to any other..** BALONEY. Just a simple one size fits all platitude. The 2A3 PP is superior to any and all KT circuits. I would bet outshoots Jadis' new super KT170 Crown Jewel.
Yes I understand as a FR sens goes up, better response froma low powered SET or low powered PP *SET type tube* 300B/2A3. But as you know the higher in sens you go up ina FR, lower the bass response, = too forward a midrange.
95db sens ina FR is my very limit. I would not buy a 96db sesn driver, as there is no way I can intergrate a W6 FR. Just 1 db makes all the difference. I got very lucky on the davidLouis VX8 95db VX6 93db sens made it by 1 db on both If the VX6 was 94db, it might cause trouble. Finally everything is falling into place. Hundreds of hours research. Lots of cash, mistakes, errors. Luck has finally tured in my favor. About to upload yet another Yaqin vid/ Might stir up the honets nest, so let me put my protective gear on....
