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.

these “shouty” type sensitive speakers can often be too bright and harsh ~~~~~~~~~~~~~~~~~~~~~~~

 

I can easily understand what you are saying about a SET witha FR/horn speaker that might have some **issues** = such as Fostex with their characteristic *shout**.

This Yaquin 2A3, is not forgiving.

That is to say if there is any **weakness* in the FR speaker,, this 2A3 will **accentuate** that **flaw**

This tiny bit of resonances (how much due to the tube typical character of a 2A3, and how much is due to this lower priced Psvane,,can’t say) ``` is  definitely there in the sound...

But I gain in resolution, instrument separation, female vocals with passion. 

The dual DavidLouis pick it up.

 

So a FR/horn that might have some resonances, spikes in certain fq’s,. whatever,,, might find this 2A3 amp not to their taste. One really needs a neutral speaker to make this amp work. So far I;’m happy with any **weakness* of this combination. Its all acceptable, nothing grating on my nerves, Nothing at all fatiguing.

 

~~Is it a sound comparable to a

Kronzilla 4 tube mono block, with AER’s top driver,

 

,,not

It is a budget system, nothing more, but certainly nothing less. How it compares to new EHKT88’s, 6 months we will find out. Afterwards in say 8 months from now, Mesh 2A3 vs EHKT88’s. More to come.....

😊

Your Merason DAC is a flies under the radar intriguing component.

@charles1dad the Merason is VERY good. Very good. Worth a listen as I can’t promise it isn’t system dependent but I have listened extensively to the Merason through an Audio Note OTO SE Signature, a Leben, two Shindo systems and it just slays…it has displaced a MSB Discrete, an AQUA La Scala Optologic and I couldn’t recommend it more highly for others to audition.

 

Now @mozartfan let things settle in. As long as your speakers are suitable, a proper kt88 based push-pull amp should not be smoother than a proper 2a3 amp, push-pull or set. Whao can say though as you have a whole lot going on there. What does your tech say?

What does your tech say?

 

 

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 

Just ran by what I said here,, &&a 2A3 has superior mids than the KT series tube..** well tech wants to know **exactly which KT are you refering to...** hummm, tell ya what,,, humm, lets say this 2A3 took me by surprised, Better? well hard to say now , as its been 4 months since I heard the KT88’s, and those had 4k+ hours and ran the KT88’s via a Thor speaker and a single FR speaker and or a 8 FR + a W4 FR, THe W8+ W6 is a whole nother ball game. So all is not even .

 

You mentioned, **KT88’s as smoother vs a PP 2A3,,** Might have to agree, **Might** as in 1st off have to hear the new EHKT88’s, mid summer 2) have to0 hear a 2A3 mesh. Late summer So **The Jury is still out..** ~~~~~~~~~~~~~~~~~~~~~~

 

What I will say is this Bottom line *IF** The 2A3 mesh plates do perform as 6 Moons says the Sophia 300B mesh perform,, well then we have a solid vote for 2A3 PP vs a KT88 PP. There does not exist a meshed KT88, only solid plates. This may give the advantage to the 2A3, Follow?? As you know these discussiions around tubes can get slippery. Not justa few weeks ago,,**SET, yeah #1..**

Now, cant say that. I actually by mistake or by lucky chance,,hit on this 2A3 PP circuit. Will the mesh elimiante some of the ever so slight harshness/in some mids fq’s??? Late summer we will know..
