I'd like to thank you for your response about your experience with tubes .
You got me thinking about trying older tubes ,
so after finding and reading about different EF86s
I decided to try a pair of 1972 NOS Tesla EF806s , the performance version of the EF68 .
I still will not take another chance with used tubes and can not begin
to afford the $300 per tube for NOS Genalex Gold Lions .
They sound FANTASTIC ,
I am now looking into finding 3 x 5751tubes since new production
is very limited .
You asked how the sound is from a passive pre-amp compares to
powered ones . Pure , Clean , un-Colored
Silvanik another McCormack owner with
a pair of CS3.6s made his own passive pre-amp and loves it .
oblgny ( page 80 ) was disappointed with a passive pre-amp .
I believe ( totally a personal opinion ) that using a passive pre-amp
allows the input to your amp to be the purest sound ,
if you don't like the sound then your input equipment
should be looked at or thought about ,
not your amps like oblgny was thinking .
Like the Thiel speakers that play the music put into them
without any coloring , that is how I feel about a passive pre-amp.
Happy Friday
Rob
