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.
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..... |
@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? |
