Best KT88's for an Mc 2000 ? Any suggestions

Svetlana is a must - I was told by people in the Mac field who should know. Superior to the 6550.
I found that McIntosh charges you a lot of money just for their logo on the Svetlanas! I saw quads of KT88 here on AG for $160!
I had to have changed a KT88 in my MC2000 and they charged me a horrific $150 for one tube!!!
Could anybody tell you how long the tubes in the
MC 2000 will last? I have VERY different opinions on that!
Cheers!

I recently purchased some JJ Electronic KT-88s(made in the Slovak republic) from Quest for Sound and really like them. They were a big improvement over the stock 6550s in my Audio Research CA-50.

The EH 6550 is a good choice.
Mac is not doing anything that any Auto Company has not done for the past 100 years.
You pay the piper when you want parts.
