EML manufactures superb quality tubes. But nothing, absolutely nothing pleases everyone. The KR and Elrog preferred by @bonzo75 will of course be criticized by another listener for whatever reason. Just choose what you find works out best for your particular criteria/objective/desires.

My understanding is that it is actually not that linear as far as triodes go but the low plate resistance has an advantage in the transformer design...or even no transformer! Most of the implementations I have owned/heard are a bit warmish in character and with balls dynamically.
Little experience with the tube in transformer coupled designs, but I do not consider that the Graaf GM20 was warmish sounding.

My Silvaweld OTLs were not as warm sounding as the transformer coupled ones…but this seems to be true for OTL in general. By most accounts though Joule Electra OTLs were richly balanced.

Preliminary report on the Allnic A-6000s.. After replacing 39 resistors, all tubes biased correctly and the amps played music.. After an hour or so we started actually listening and were immediately pleased.. The music and space were well resolved an dthere was lots of space.. They didn't sound warm or cool--merely just right, especially they haven't played music for many months.. They'll be burning in 20- or 24hours per day for about a week.. Have a set of Emisson Labs 300B-XLSs on the way, and I'll be doing some Voltage measuring on the plate resistors and 300B filaments for resistor replacements as the next upgrade work.

You mean you don’t know?

you brought in 32b and 62b Ayon into a discussion of EML, KR, Elrog, and with the face they are transparent and added the fact they are made by EML. So up to you to say how it is relevant to the point if KR and Elrog are more transparent than EML or not, or if you are just causing data noise, or if you actually either compared to EML in same amp or to KR and Elrog

Triode Corp of Japan TRX-M845 Monos 50 Watts Parallel single ended. Will take 211 or 845's though I prefer the 845's. Speakers are Fleetwood Deville supplemented with a pair of Magico Asubs.
Honestly thought Tri wasn’t around much anymore. They had some buzz 5 years ago.

No, you made a blanket statement about EML tubes. You have heard Ayon products that use these tubes, no?

Joules were very warm - and extremely hot!
My Silvaweld OTLs are still to this day the hottest amps I ever owned…and they only had 4 x 6c33c per mono…some Joule amps has much more than that!

No, I made a statement after comparing them to KR and Elrog in two different systems, and comparing KR and Elrog in others.

I heard Ayon products separately including these tubes

I'm confused, is there a debate happening on this topic?

You clearly stated your impression, Charles stated his, and then you make the point that he's probably listening incorrectly or using language incorrectly. Nothing's going to change your perspective, which is totally fine, but let's not pretend that any actual debate is happening.

my reply was to morricab, not to Charles, it is a separate strand, keep up.

Hahahah. Yes, and quite specifically on the same topic of EML vs. competitors.

You are out of luck. This is the problem of "warm tube sound", in our country it is also called "grandmother's radio". This is not a problem of the 6C33C tube, it is a problem of the amplifier designer.

SE amplifiers from my photos have incredible dynamics, they easily replace transistor PP amplifiers in a home system.

No affiliation, but there's another allnic a-6000 up on usaudiomart for what looks like a decent price. The ad claims the (additional cost) eml-xls tubes are the preferred choice of the designer...
https://www.usaudiomart.com/details...itor-upgrade-10-eml-xls-300b-tubes-available/

I presumed it was already Jeffrey's and we just hadn't gotten the listening impression updates, but it isn't.
This is why I am interested in the listening impressions of @jeffreybehr. EML are simply splendid in my experience, so curious as to his findings.

Actually I am quite lucky as I have wonderful SET amps to play with...
