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.

Best bang under $1500

Got lucky on this gamble

Proclamations are difficult to back up. I will say however that DHT tubes such as the 2A3 are terrific sounding when well implemented in an amplifier, be it SET or push pull topology. Congratulations!

Catching up, what a surprise this turned out to be, whole bunch here actually seem to understand Lewis Hamilton was robbed, and Verstappen handed a world championship. All the drivers knew it was a cluster in real time as it was happening, as their live radio shows and the more experienced (Vettel, Alonso, etc) the more they knew it. Which being so obvious makes me all the more pleasantly surprised, and credit where credit's due. May be hope for some of you guys yet.

Proclamations are difficult to back up. ~~~~~~~~~~~~~~~~~~~~~~~~~~ True 'I've nor heard every EL34,88,120,150 tube amp ever made. based on a few models,, these tubes **pretty much** all sounded the same.At least to me ears. hardlya nuance difference. THe pre tubes in each design responded much more to preference. I'm a Tele fan. So like yeah,,here I am thinking 2A3 wow doube tubes,, read the descript,, now that i think about it, it might have added the one word PP, but also thought it did say, SET...The Inet only mentioned the 2A3 in a SET design,, so I'm thinking its a SET tube. Someone here on Audiogon, noted it may be a PP,, My tech confirmed and brought the ad up on his computer,,anyway, he said, **you might like this chinese budget amp,,then again...**. Yaquin has always been in my mind like Ming Da, Dared, the low budget end of chinese gear.. WEll turns out I much prefer this 2A3 in a PP vs all KT varieties, (exception is Jadis' new KT170, which looks promising but at 10x's the price of this lil Yaquin..). Anyway, listening to a classical cd recorded poorly from Russian Archives, sounded fantastic on the 2A3. Faith Hill never sounded as good. There is no doubt, this 2A3 out performa s , all KT designs. I've yet to hear Full Music Mesh plates (my tech mentioned its nota true mesh, more like perforated metal..), still from what I've read the Mesh offer nice resolutions. The Jadis Defy7 will be great in more comples symphonic orch,,but for all other music, this 2A3 will beat out the Defy.

Your tech is correct,  perforated metal plate rather than a true mesh design. EML makes a genuine mesh tube, they are costly.  You could still really appreciate the sound of the Full Music perforated plate tube once acquired. I can understand why you are attracted to DHT tubes (101D in my preamplifier  and 300b amplifiers). Pure musical beauty if implementation is done well. I feel that you're on a good path.

Again its my opinion 

the 

2A3 PP is superior to

the EL, KT series PP amp.”

+1  Totally agree!  I also prefer the 2A3 over a 300B in a pure SET amp.
