You might take a look at audioasylum.com and the tubes forum. A search on 6550C or KT88 will turn up a great number of opinions on just that comparison. I found over 200 hits on just a quick search.
Are KT-88 a good substitute for 6550c?
I have a VTL stereo 150 amp that uses 8 6550c tubes. I usually replace them with the Selvtlana 6550c. I was told that the Electro Harmonix KT 88 was a better sounding tube, more romantic less punchier than the 6550's. I would like to try them but don't know if this is a good idea changing tubes.
Does anyone have any expierence with this.
Thanks
