The future of preamps

Swampwalker:
I have to set the record straight for you, not once have I trashed the sound of dc coupled output tube preamp. In fact as active tube preamps go it would sound the most transparent way of doing it, no coupling caps in the signal path on it's output.
Unlike 99% of most tube preamps that have coupling caps or transformers on their outputs to stop any dc from getting to the poweramps.

It's fact that if Audiolabyrinth uses it with a dc coupled poweramp like his Krell, should any fault cause dc on this preamps output, it will take out the Krell and most probably the speakers as well. As the Krell's engineer's have also had the same concerns.

As if a dc coupled tube preamp going faulty the dc offset on it's output is far more deadly than a solid state preamp going dc on it's output.

Audiolabyrinth just wants assurance that this will not happen to his prize Krell and speakers.

Cheers George

So far no one has pointed out the obvious so maybe it does not need saying, but a review of this thread and several others leads one to believe that George is "defending his turf" by talking trash about competitive active pre-amps.

Maybe it's not obvious that George is "defending his turf" so no one has pointed it out. Just 2 designers disagree on principles in building a preamp and is getting personal.

@ Georgelofi, Thanks, you hit the nail on the head with your post!, I love tube products!, I am just repeating what the service manager said to me at krell, that does not in no way make me the idiot!!!, I have no idea why JWm would put such a poor comment on this thread!, Very un-gentleman LIKE and un- called for!, I feel that Ralph's pre-amp is one of the best, why would anyone think I said something bad about him or his pre-amp?, I HAVE NOT!, Thankyou Almarg, very good valid point of your post, kinda looks bad for krell to write such things, cheers.

@ Atmasphere, Hi, I have said numerous times thru-out this thread how I respect you and like your designs, I hope you set the record straight with JWm and others here, they need to re-read some post!, Ralph, I have had alot of bad things happen to me in audio recently I have not disclosed on this thread, I apoligize if I was mis-understood, these mishaps that I have been thru costed thousands of dollars!, I was in no way at fault for what has happened to me, I have had a $6,350.00 tube cd-player blow up with-in 90 days of new, I have had tube products emit DC, I had to totally renew my amp at Krell!, that costed me $3,150.00 dollars!,the amp just came back in october,2013, Its still in the krell box, The good thing however, Is the amp got caps that was not available in 2005, Krell claims it is a better 700cx then when it was first made in 2005 or better than any 700cx amp out there, Krell said that, not me!, Krell claims I have the first and only amp like this, so in the end, I hope you understand why I am so worried about my investments!, nothing personal at all directed to you, and I would never be a person to give you a bad tiime after a sale unless I have litterally the same problems listed on this post!, Highest regards to you Ralph, Thankyou.
