However, g, I know we at least can agree to disagree amicably...and healthy skepticism is vital in any worthy debate.
It has always been my practice to disagree politely and respectfully. However, your recent postings misrepresenting my remarks does not make it easy.
Well mordy...it looks like you - just as did JV - have shown that the 6N7G in our Elises can in fact perform FAR better than in gibosi's Glenn amp. Which makes good sense to me, as the two amps are obviously vastly different machines! The Feliks-Audio guys have inadvertently created something that is
way more versatile than we ever even imagined just a short while ago - Lukasz himself can hardly believe what we have been doing with his baby...or the ensuing unexpected results, lol!
I posted that I compared my 6A6 to my best 6SN7 and found them wanting. For you to then say that these tubes perform FAR better in the Elise is a gross misrepresentation of my observations. And since you have never heard a Glenn, an unfounded statement like this is simply irresponsible. When someone compares their 6N7G to the same 6SN7 in their Elise, then we can have a meaningful conversation about differences, if in fact, there are any worth noting.
Anyway, back to sound perception, lol!...I can assure you the FDD20 and ECC31 are in no way like having a 650 in one ear and an 800 in the other!! And it is becoming more and more clear that certain tubes are performing very differently in your Glenn amp compared to the Elise...they are indeed quite different animals, lol! Therefore, we can only gain true impressions of the tubes we are using - including 'oddballs'! - when more Elise owners are able to give their own impartial assessments...warts and all, hopefully!!
. We are all on quite a journey, methinks...
Again, here you are saying that certain tubes perform differently in the Glenn when you have absolutely no data to substantiate such a claim. Up until now, my impressions of the various tubes discussed in the Elise threads have been in substantial agreement with Elise owners. Moreover, when we first began rolling ECC31 and the FDD20, you and I substantially agreed that we were hearing the same thing: The ECC31 has incredible bass, but the overall presentation is somewhat laid back. The bass on the FDD20 doesn't match up to the ECC31, but the overall presentation is a bit more forward. I would encourage you to go back and reread those postings.
Also, it doesn't matter one bit that both the ECC31 and FDD20 came out of the Philips fold and might even be using some of the same components. The fact remains that they have different electrical characteristics and they do indeed sound different. And in fact, if they didn't sound different, I would guess that you would have had no interest in running them as a pair. Each has different strengths and weaknesses, and putting them together, in your mind, gives you the best of both.
So there is no doubt about it. You are now running an amp which processes the right and left channels differently. And in effect, this is no different than listening with a customized set of headphones. I simply used the 650 and 800 as an example, but the point is, dissimilar drivers is similar to having two different headphones or two different speakers. And again, the end result is the ears are receiving two signals that have been processed differently, whether through two different transducers or two different tubes.
This is certainly not what most people would call high quality audio. And I am quite sure that if an audio company were to produce and advertise an amp that did exactly this, process the right and left channels differently, they would almost certainly be laughed out of business. But here in the Elise forums, this practice is defended with the utmost seriousness. No laughter is allowed.
What I find interesting, Colin, is that while we used to agree on the sound of these tubes, you did not begin to assert that these tubes are performing very differently in the Glenn until I pointed out that the FDD20 and ECC31 are "totally different drivers". A coincidence perhaps?
Anyway, until recently I have enjoyed spending time with the Elise crowd. It has been fun. But from my perspective, things have changed for the worse. It is no longer fun... And shame on you....
