New KT150 tubes?


Has anyone any experience with these pretty new tubes. There are already one or 2 amps I know of, that use them. The review of one of these amps in a UK magazine suggested they were a little warmer and more natural sounding than the nearly new KT120's

The article also suggested they were a straight swap for KT120 based amps, with no adjustment necessary. They are more than twice the cost of KT120's, but still not too costly compared with NOS tubes. I know changing from KT88's or 90's to 120's. did require some amp modification. I have an ARC reference 75 and might want to try the new tubes at some point, ARC don't seem to have a customer E-mail service, to ask the question

Hi Knghifi, A friend of mine had a new pair of GT 200's recently built for him by Paul so I fortunately arranged for him to sell me his "old pair". I had him ship them directly to Paul where he pretty much gutted anything not worth saving and replaced 'lots of stuff' including all new transformers as well as new Duelund cast caps. I also had him send the faceplates back to the anodizer where we had them done to match the one on my Dude pre-amp(Gun-metal gray). They are simply the most musical amps I have ever heard and when combined with the Dude (also Duelund cast equipped) and my Lampizator Big 6... it's truly sublime. Yes, I feel Paul's equipment really does compete across the board with almost anything out there?!? Thanks for your interest and kind words.
Btselect - Thanks for the info. I just wrote to Mick at Dynaudio to ask Andreas if the KT150's will be OK in the V110. Mick's response is Andreas is currently working with them in the V110. Makes me want to try them for sure.
Btselect - Forgot to ask. When you compared the KT150's were they fully broken in? I ask because when my KT120's were new I really liked them. After 100 hrs I had to take them out. Too forward and a bit grainy. I loaned them to a friend who said he loved them. He put about 150 hrs on them when I got them back. I tried them again although better (very linear) I also replaced my driver tubes (Telefunken 12at7's) with some warm sounding Mullards which helped even more but still not as good as EiKT90's.
Lissnr, Congrats on a terrific system and I would love to hear it. It's unfortunate not enough audiophiles get to experience Paul's creations.
Just sent off another e mail to Kal at ARC about the KT-150. I'll post his response when he comes back to me.
