SET Shootout China VS The USA

@mozartfan Man, you're all over the place, too many bold pronouncements about this or that being best. I love SET, and have two actual SET amps and one pp. Own or have owned two 845, one 300B, one 2a3 for SET. For pp, EL34, 6550, KT88, KT120, 6CA7. To say any of these tubes or amp topology is best simply untrue. I've enjoyed both pp and SET and all these tubes at one time or another.

I'm Verstappen  and Red Bull fan, not into Hamilton or MB, but I'd have to say Hamilton and MB got ripped. Hamilton increasing his lead with worn out hard compound tires, he was cream of crop that day. What officials did was NASCAR shenanigans, fake competition.

If this is Yaqin MS-2A3, makes no claim of being SET. states its PP, I see claims of 10-14wpc.

Whatever Yaqin model it is, likely combo of decent parts and others needing upgrading. That's been my experience with chifi relatively lower price equipment. Hopefully, they have decent design, in looking at Chinese 845 amps a few years ago, some were grenades just waiting to explode.

@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.

Shuguang is separate entity from both Psvane and Linlai. Shuguang government entitiy, Psvane and Linlai privately owned. Psvane principals originally with Shuguang, Linlai principals left Psvane.

And the top lines of tubes from Psvane and Linlai are obvious upgrade from lower lines, assuming one's system sufficiently resolving.
