Mike,
Glad to see you went for it, and that you can appreciate the benefits of the "e" (evolution) upgrade.
I consider my K-1xe to be one of the cornerstones of my system, which means I doubt I will be upgrading beyond it for a long time, if ever!
:-)
That being said though.....
Don't you just long to hear the new Ayre KX-R preamp in your own system?!
I know I do!
But man, the $18,500 price tag is surely going to slow me down from getting it, as even used you can bet it will run around $14K for the next year or two.
And, since it does not have a phono stage, (I listen primarily to vinyl), that means that I'd end up having to spend money on a separate phono stage, and a cable to connect the two. (And since the phono stages I know I'd want to upgrade to, from the excellent Ayre phono boards, are both very expensive (Manley Steelhead or the ASR Basis Exclusive - both around $4K used), I doubt I will be upgrading anytime soon).
That would mean spending close to $20K on the new preamps. Ouch! (I spent $4K for my Ayre K-1x, and $500 to upgrade it to the 'e' version. Quite a bargain, IMHO!)
Oh well, I can dream!
