I have yet to hear a Sylvania 6SN7 I don't like, so I am not at all surprised they sound brilliant!
And as my LD 1+ is an op amp hybrid, I am not able to try 6SN7s as output tubes, so I am a bit envious...
I am thinking I should get another amp so I can roll output tubes.... But for now, new headphones are a higher priority.
gibosi : hope you caught my post re the Psvanes...have some reflections after on what I think may be a couple of rather controversial/interesting? topics...but first, to perhaps shed a little more light on the 6SN7 as power tube quest, I'm glad you like the Sylvanias - I've a pair of VT231 on the way, which I believe are not far off the (real) "Bad Boys"? So I can't wait to see how they compare to the Psvane CV181-T MKII...
And now for something that hopefully might be of interest also to anyone else who may be following this...
FOLKS...After just 4hours (of the optimum 100!), these Psvanes are obviously going to easily surpass the 6N30P-DRs - which is generating some VERY strong feelings in me at the moment...over and above the euphoria!
To tell the truth, for some time now I have been having serious doubts about - (what I am now fairly convinced to be true) - the myth surrounding those Russian "Supertubes" (at SUPER prices).
The first hint there may be something in it came from a forum post where someone (who seemed to know what he was talking about) actually rated the performance of the 'humble' 6H30Pi OVER the DR. At the time I thought it was down purely to personal preference...but now that I am hearing what these Chinese tubes are doing (admittedly not the cheapos), my suspicions are definitely looking more founded in fact ( to me anyway). I am quite sure the Sylvania VT231s will prove it beyond doubt...but we will see!...
I am going to be generous in my disappointment, and put this down to SOLELY because of traditional partnering with less-than-ideal drivers, thereby making the DR
appear to be a "supertube", when in fact that was not really the case...
Which brings me to the second 'myth' that I feel needs busting - ie that (in our LDs, at least), the power tubes do not have a great bearing on the final result...these Psvanes are
definitely disproving that one - already!!
So, folks, I am convinced that the Meisters in this thread, through the relentless trial and error of tubes that were never envisaged at its outset, have hit upon some EXTREMELY interesting and RELEVANT pointers that go beyond the mere 'improvement' of what our units can achieve. And I honestly believe that although we have found drivers that can transform the sound we enjoy, the biggest advance will in fact lie in this area of power tubes...even if only to save just 1 person from being 'robbed' by the "Supertube" myth...I welcome any (informed) challenge to my rant...and I am quite sure my suspicions will be upheld by others who tread this route to alternative power tubes.
Rant over...back to seeing how the burn-in is going...
Cheers, and HAPPY ROLLING everyone.
