What is the "sound" dif. between a Joule -Elctra OTL and a SET amp??

Ralph, 
I didn't use the term lean with negative connotations but simply as a relative comparison based on my listening experience  of it compared to my current amplifier.   I haven't heard the Joule OTL. A friend of mine is familiar with the Joule  and the Atma-Sphere OTLs. His impression of their tonality is  the same as Larryi. Not a case of  better /worse but different presentations were observed. No question that speaker or system compatibility would favor one over the other.

Ralph,

 If the OP were to limit responses to only those with experience with Wyetech and JE, crickets would be chirping. The OP's post is titled "What is the "sound" dif. between a Joule -Elctra OTL and a SET amp??"  I responded in accordance to what was in the title.

Being a former longtime Joule owner, I was trying to give the OP information from someone with the actual experience of owning a Joule amp. That's all, I wasn't trying to make it into a Frankenstein thread. I mentioned the brand and make of my amp, and a brief description of what I am hearing from that amp, to give the OP perspective on where I am coming from. That's all.

I had a few sources for 6c33c tubes that I tried. Joule Electra was the main source, but they went out of business and stopped selling tubes. Upscale Audio was another source, and they did not have any in stock. Another source was a popular Russian tube seller whom I had purchased from in the past, and they surprisingly did not have any either. There were a couple of other well known US based tube sellers that did not have any either. This was two years ago, looks like things have changed.

Peace,
Tom

guys-just coming around on my amp selection as life gets in the way- I just picked up a set of Joule- Electra VZN-100 mk V(Green Board) and a LA300 Marianne preamp- they def. take a little time to get used to -Playing with the variac and biasing each tube and they def. throw off the heat!!- But they are by far and away the best amps I have had- The Wyetech has excellent build quality but the sound was almost sterile in comparison to the Joules- Even though rated about the same power 100 - the joules seem to have alot more power-They throw a huge soundstage in every direction- There is a slight buzz from the speakers but you do not hear it when listening to music- they are def. a keeper- thanks to all who gave advice-

@fluffers Congrats, awesome gear & match. Cheers,
Spencer

I am also a new owner of a vzn-80 amp along with the La300-me and I agree with fluffers. It is a great combination and I am very happy with the combination.
