SET Shootout China VS The USA

@larryi

I know that there is a strong desire to come to conclusions about various aspects of design or parts choice, but, it really is not that simple to do. The more I hear, the LESS I am able to draw definitive conclusions in these areas, although I do see rough tendencies.

I can appreciate @mozartfan’s enthusiasm with his recent discoveries, but do agree with you concerning broad sweeping conclusions. I will say that DHT tubes just seem to produce a very impressive natural sound that I find exceedingly special.

I will be the first to admit however variables such as builder/designer talent, attention to detail and quality parts selection are crucial and vital factors. We all have our preferences. DHTs used and executed properly simply get it done for me.

BTW the 307 tube is not a DHT but is in a fact a pentode tube.

But it sounded like a SET DHT in the Youtube video!

@charles1dad @larryi and @alexberger well said all around on tubes and the Japanese influence on audio. And @pesky_wabbit what amp are you running?

@mozartfan you're getting tons of great info and advice on this thread but you need to start listening to actual amps and not youtube. You seem to have a good tech maybe you could commission him to build you an amp or two using these tube types that fascinate you?

well what we are all finding out is that there are such amplifiers as 

 

~~~DHT PUsh Pull~~~

Ner heard such a  design.

All I knew about is SETSETSET.

A SET on a  xover type speaker does not work, I tried it, its  a complete failure. Either high end horn or FR (or Concentric if that floats your boat, Tannoy.

My next experiement is to find out if the KT88 ,,,lets say, how dif in  nuances /midrange is the voicing on a  KT88 vs  a  KT90.

This is my next experiement.

I'm holding out hope for my PP amp.

What can a  KT90 offer paired up witha    dual FR.

The 88's were just a  bit too midrange heavy to work with dual FR.

Its like midrange X's 3.

From what I remember of the EI90's in the JOR, there was magic in the soundstage.

= more recessed midrange.

I think everyine goes for the 88's as their xover/low sens speakers needs all the  voice they can get in midrange.

 

This is why they choose 88's. 

The 90 has been completely totally thrown under the  bus.

Google kt90 on audiogon,,, haha, maybe 5 posts on that tube past 10 years. vs 88's, 100's of posts. 

Its all which 88  is best.

Audiokarma, DIY, all sites, 888888888888.

If I can sell my cayin  cd17 I can get the 90 tubes,,,no bites 3 days,,,,,, priced rock bottom  w mundorfs.
