If you're happy with those NOS Mullards, then just sit back and enjoy them for a few thousand hours. At some point down the road, try to find a good set of early 60's Siemens CCa tubes and give them a try. If the Siemens don't suit your taste, then pop those Mullards back in and enjoy them for another few thousand hours. In the meantime, if it's the Mullards that you enjoy the most, find another spare NOS set and tuck them away in your tube stash to eventually replace your present Mullards when they wear out. Enjoy your system.
A higher level than Mullard in tube quality?
I am just getting started in tube rolling which I find pretty exciting. Any thoughts or comments would be appreciated.
I have been upgrading the pre-amp tubes in a DK Design Mark II intergrated amp. My speakers are modded Magnepan 3.6's. My source is a Resolution Audio Opus 21. I listen to mostly acoustic jazz and vocals.
I went from a set of Electro-harmonix 6922 (like $20 each) to used 6dj8 Amprex "Bugle Boy" ($40 each) and that was a nice improvement -- well worth the cost. I just upgraded to Mullard 6922 NOS ($90 each) and WOW! I am amazed at the improvement. I could not have imagine that I could improve a $10,000 rig so much for so little. Now I am thinking ... what's next? Can I spend $300 and get another step up?
At this point, what is my next level up? Or is it more sideways to different type of sounds?
Question: used tubes of the same vintage are significantly less than NOS. Is there any down side to buying used (but tested) tubes? I can get 2 for the price of one NOS and probably get more hours from 2 combined. Also, it seems like a good way to lower the cost of testing different types of tubes ... or ... does the aging change the sound.
Question: I have Mullard Blackburn plant made 6922/E88CC gold pins in GE label from the 1960's. Would I get a different sound if I bought different Mullards, such as from a different time or a different plant? And do I just have to take the dealers word for the details -- it all seems so vague.
Right now I have $300 burning a hole in my pocket to try the next step up. But I fear I may hit the diminishing return ...
Thanks for your comments
