The future of preamps

@ Atmasphere, Hi, I am really interested in your preamp to audition, I called my friend Ray Munchler, the service manager at Krell today, He said he would research your m-1 and give me his thoughts on useing it with my Krell 700cx, I like your circuit you designed!, no coupling caps, no transformers, Like to hear that, I know Krell is bias to solid state, However, Ray is going to give me his honest opinion on the matter, I believe no one knows Krell like krell does, His concerns is DC!, He believes before looking at your m-1, I may have to activate the coupling caps in my amp to use it, I will not do that, this will indeed degrade my sound performance, formost, you have been very nice to me and patient, Thankyou so much, you are a real gentleman here, you have my respect, I will let you know what Ray believes, happy new year.

@ charles1dad, Hi, I like you as well, you are a gentleman, I am tring to sort all this out and hopefully accomplish a match for my amp, Its sad I have to be concerned with what I do here, being Krell is saying repeativily about tube preamps with my paticular amp.

@ Atmasphere, Hi, Just got my call back from krell, they said, If you have it in writting in your manual or other wise that your preamp will not emit Dc at all, its all good to protect my investment!, He did want to know what kind of volume control you use, He also said, If its the old school pot volume control, it would not matter since you have dither controls for the gain, He said I should be able to ajust to match the amp, he preffered discrete attenuator volume control, meaning, has digital support, they veard off from the usual pot volume control for better out come of sound, what say you?, thanks Ralph.

The volume control in the MP-1 is a custom-built switch with gold contacts and dual wipers to insure contact performance. It has 4 decks so we can control each phase (inverted or non-inverted) as well as both channels.

@ Atmasphere, Thankyou for your reply,I will try to give you a phone call after new years to find out the closest place for me to hear your preamps and if you have documentation saying that your preamp will not emit Dc into a amplifier. Happy new year!
