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.
What you’re referring to as "SET tubes" are technically DHT(Directly heated triode) true 3 element tubes (45, 2A3, 300b, PX 25,211,845, 805,50 and so on). Your reference to "KT type tubes" are IDHT (Indirectly heated ) with most of these tubes being pentode, 5 element constructed tubes. You are discovering the world of DHT tubes. Welcome😊, there’s a ton of information available via search that can go into as much detail as you care to explore and learn. Charles |

**another world**. Bigger.
Another universe. As you were typing this message,, I was on the Inet searching these *DHT** tube designs. I’ve heard amazing things about the **45**, and other DHT tube circuits Just unreal. WOW factor off tjhe charts. Look its high time we get off discussing KT series tubes. Audiogon past 20 yrs has been ALL about KT series tube designs. I;’m sick and tired of of the old standard fare, like stale bread./ Yes a KT is a nice sounding tube. But it ain’t nothing special such as these DHT’s deliver. 2 **completely** (hyperbole necessary) different soundstages. You guys know how far I’ve gone in hypeing FR speakers as not only the best choice, but,,,well I refuse to finish the sentence... Again here with the **DHT** Universe discovery,, the sound fields lifts you off the earth into a new unknown (KT exp well known /explored) planteary system. For months I was perplexed as to what amp design will open up the magic of a FR system.. I searched all and evey KT offer. Close to addinga 2nd KT series, like a EL34 low watt amp,,, By sheer luck (man do I need a break on luck in my choices lately)) I hit on this 2A3 PP rare gem. So as we close out the year, i am going to add to my prognostication (big word I know, but have a bit of that old spirit with me,, a bit I said, not to the degree of the old masters). FR as speaker choice, 1st system, wearing crown jewel And these DHT SET/PP as the preminent place among audiophiles choice in amplification power. Its comming, I can see it, but its still some years off. Sterophile, 6 Moons still pumps out massive does of propaganda fopr the big KT power tube designs and the speakers that go with these sheer power blocks, the low sens/low efficient blood(fidelity) sucking xover type speakers. Neither of which is going away anytime soon as 1st picks.
~~~But a time is comming~~~ KT amps will be offered at *dime a dozen* prices on used retail sites. Rock bottom. Whereas you’ll be lucky to find a good deal ona used SET/DHT type amp. = Minisclue discount. maybe 10% off list. vs PP amps, now nearly 30%++ off list. jadis DPL Linestage, with takman, Mundorf and Teles, Jadis Defy, Takman, Mundorfs, Teles,,, I gave jadis all the best,,But its no match fora DHT PP 2A3 design. The future is ~~~FR + DHT~~~

and here ya go WOW factor off the chart. These designs are blast off rocket ships to a magical musical universe. Your music will never be the same. Will never have sounded this good. You will RE discover your favorite music. As in,,**WOW I never knew this singer/ band had such talents..** http://www.triodelab.com/45-triode

The 45 tube is a fantastic tube to many DHT enthusiasts it's their favorite. However because of the exceedingly low power it's not for everyone and proper speaker matching is essential. I prefer it and the 2a3 both to the 300B tube as a general rule but obviously that's amp dependent there are tons of good 300B amps out there. |
