KT 88 by EAT vs 6550

in my opinion this kt88 by EAT is worth every cent... the tube is the wrong part of the audio system to save money... it is like to buy a ferrari with a fiat motor...
my convergent jl2 now sounds better then every amp I heard... and my new eidolon diamond..... are really flying to the stars...
I recommand strongly this tube, also for audio research reference 600 amps..
ps Are you sure 250 usd/pair is the correct price?
ciao

I saw a website selling them for 90 pounds apiece. How much is that in dollars?

ouch. $250.00 for a tube is some big bucks...then again I think of what I have spent on interconnects....
