Hi Charles,
Hope all is well .
Its been a while since I visited the Audiogon forums and am slowly getting up to speed.
Like you,my goals in any improvement or evolution of my already very satisfying system is always the "organic factor" over anything else.
Sooooo...It looks like I have to get the Elrog 300B tubes!!
In combination with Mullard GZ37 rectifier tubes, whose impact on sound quality improvement were huge,the Elrogs should really make the Franks sing .
I'm hooked and I cant wait to get a pair.
I know we share similar values and choices on our hardware selection based on our "sonic morals" so I respect your evaluation and know I will be in for a real treat.
Thanks for doing the leg work and investigations for me and the other worshipers!
Regards,
David
