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.

Why are you supporting China's economy? I don't get it. I can understand an iPhone only.

One thing I've learned in audio is there's always something better ~~~~~~~~~~~~~~~~~~~~~~~~~~~ WEll sure I mean if we bring Kronzilla and Wavac into the discussion, Jadis has to take a distant 2nd place. There are other UK designers also employing the 833 and other super massive exotic SET type tubes. But in its price category, Jadis reigns pretty high up there in craftmanship. This is my point, Jadis eraned and well deserves its reputation. Is my point. I did go a bit hyperbole when i said **THE most** when in fact truth is, **among the most mucical in that price group..*

Dac chips until this thread. So thank you for that if nothing else. ~~~~~~~~~~~~~~~~~~~~

 

. I’ve had the DAC now 9 months.

Yesterday was a very wet 100% humidity and cool. I’ve noticed during a rain , next day, DAC needed **drying out time**, Yesterday was the worst...So what i am doing to help prevent this longgg dry out time,, is 1) placea paper bag over top of unit where there are vent holes placed along top, 2) turn DAC on early in the AM< WITH bag left in place, this way heat builds up and drys out any excess moisture. Beats using a blow dryer, which did not help all that much... , Also I could put back in the window my 5k btu window AC and run it at night, like a dehumidifier. If I have to I will. I note the pops are more frequent while in play, with all my jazz /pop cs which have some marks on the surface,, my classical cds are near mint have less pops. So the entire Shamling drive + DAC together are being sensitive to excess moisture + cds in avg condition. This issue only happens on certain super high moisture days. 100% humidity + rain + cool front which makes air highly energized wind = static energy. This Jadis DAC is loaded with chips + the Class A JFET opamps, loaded with tiny cjips. All make for highly sensitivite DAC setup to moisture.

Why are you supporting China's economy? ~~~~~~~~~~~~~~~~~~~~~~~ Look I am completely with you on this one. Chinese intellectual theft is real and affects us all here in the USA, in one way o more. I don't like what the chinese do, robbing our technology and then branding it and we buy it. Its theft. But in this case, I can't afford the other high end manufacturers ofg FR speakers nor the higher end amplifiers made in the EU and USA. Also are there any USA manufacturers designing a 2A3 PP amplifier at the moment? At a price I can afford. In this case, hats off to china for bringing me wonderful components which fulfill my long quest for a beautiful musical soundstage.
