I've been running four KT-150 in my VSi75 for about a month. At first I was enthusiastic. The sound has more power and more depth as somebody else already said. But, it sounds a little less "sophisticated". It sounds great, but has less finesse. Maybe that's the difference between something that is specifically designed around a specific tube. Anyway, if you like more power in the most basic meaning of the word, this is it. What a bargain upgrade.
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

Just found this on another site. No mention of pricing |
That info is from here: http://audioshark.org/audio-research-corporation-arc-36/arc-amps-kt150s-6541.html I am sure tubes from ARC will be a premium but probably matched better. |
