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.

@mozartfan sometimes the crowd is actually right ~~~~~~~~~~~~~~~~~~~~~~~~~~ My mantra is Never ever follow the crowd. If I go the wrong road, I tack it up to exp. Otherwise I follow my own course after my Thor upgrade disaster and listening to my tech saysing **Yes seems 1 of the 15 year old Millenniums are 1/2 ohm off from the other,,,better spend $700 on a new pair..** so I did,

For absoluetly nothing.

Both pairs sound identical. Tweeters last FOREVER if not abused, only swap out diaphram every 30+++ years, Thats it, $50 bucks. Remember what old Frankie sings **And I did it my OWN wayyyyy** I never ever follow the crowd.

I prefer Faith Hill, Diana Krall via the 5% distort 2A3PP vs a KT88PP. All day long. My suggestion is if you are going into a FR system as a 2nd system, this is the amp to buy..

 

Sadly you lost half of your audience with your first sentence and the remainder with your last sentence. 

@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.
