Here's what I don't get. It seems that some here think that one shouldn't change caps, pots or even tubes in Suprateks simply because, "Mick didn't build 'em that way."
I think that is just so much nonsense. As much as I respect Mick's work, he's not God. I clearly happen to disagree with him on the DACT and the V-Caps. That's okay with me that we disagree, I still respect his opinion, I just have a different one.
Ralph Karsten of Atma-Sphere also has a different opinion. He offers an expensive cap UPGRADE on his preamps to guess what ... V-Caps and I think Ralph has a pretty good reputation in the business.
I find it ironic that while some believe that Mick's preamps "shouldn't be tinkered with", Mick offers this on his website:
"The Cabernet Single uses 6SN7 and 101D tubes , but can also be ordered with your favorite DHT tube. Choose from the 45,300B or 101D (standard) or if you would like to hear the lush smooth tones of a genuine 1930's NOS tube we can supply the single with 6SN7 and 33 tubes..."
Well, what the hey! That's some major tinkering.
To some it's heresy and just short of a crime to change to a cleaner, clearer, better defined, more musical cap (V-Cap or Mundorf) or better attenuator (DACT) because, "That's not the one Mick uses." However, I'd bet these same people would find it perfectly okay to change to a 45, 300B, 101D or a lush 33 all in the same preamp simply because Mick says it's okay on his website!
Hey, sorry for the rant, but it's silly to think that four different tubes can be chosen for the same preamp to alter the sound to one's preference, but heaven forbid one should change a stock tube, cap or pot!
Don't get me wrong. I think Mick's preamps are works of art, but I'm still going to trust my own ears no matter who may have a different opinion.
