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.

My preference for the 2A3 SET has more to do with horns/lowthers . In my experiences, these “shouty” type sensitive speakers can often be too bright and harsh. The 2A3 seems a bit more unforgiving, albeit with less drive too. for years I tried to scale out the SET sound of these tubes, to achieve their sound on a more conventional speaker/setup. They are magical indeed.. it’s their simplicity that makes them so special. |
Thanks @charles1dad as Ive stated a few times on this forum, we prefer our audio systems to live with us rather than the inverse. The system to which you refer is just that….unlike some on Audiogon, our systems aren’t intended to evoke wow comments from guests, 7nless its playing music. |
to hear a good quality 300b amplifier and decide for yourself.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
WEll I've learned to take what he says with some ~~conisderations~~~. He has his opinions, but certainly with more experience, He has desined a 300B SET.
Again, with so many big designs out there in the 300B, the tube must have some magic, otherwise no one would buy them.
I'm glad this amp turned out to be a PP vs my misunderstanding it was going to be a SET,,Actually soem of the SET linear magic has worn a bit thin,,now that the initial **WOW** exp has passed.
I perfer this more dynamics of a PP sound.
There is a bit of harshness to the 2A3 vs the KT88.
Hoping a higher quality *mesh* plate resolves a bit of the resonsnces,
But what i am hearing is well worth the minus ofa bit of resonaces, aka distortion,, (5% for this tube).
My tech thinks the so call *mesh* plate , might be a bit of snskeoil,,hes skeptcal I'll get any gains vs my current Psvane.
However reading a 6 Moons review on the Sophia Electric 300B Mesh, if even half of what the review say s is true, I'll bea happy camper.
The Full Music looks identical to the Sophia.
I will bea unhappy camper if the gains are miniscule nuance, not for $600/quad.
