McIntosh MX 119 Preamplifier vs Adcom GFP 750

How long do the tubes themselves generally last ?
Do they all degrade at the same rate and just replace all of them when its time.
The other solid state I’m considering is the McIntsosh C47.
thx
for info

I think they would wear at the same rate, generally speaking.  The Freya+ doesn't have a phono section though, you'd have to get a phono preamp separately if you're into that.  

Your choice of cables with it ?

That might be speaker dependant, but I've got silver solid core IC's from the freya to the amp, and Morrow silver plated copper on the cd player.  With the tube section engaged, it gets really captivating.
