Pass XA 160 review:life span is 6 years?


Hi
In recent Stereophile review of Pass Xa 160 i remember reading that it's life span is 50000 hours.Does that means if in a near future i see a 6-7 year old Xa 160 for sale i should avoid it?What about those monster Krell amps that keep on working after 20+ years without being turned off?
What in this case is a life span of X250/350?Is it why there are so many X250/X350 amps for sale?I appreciate your replies.

"I thought the Aleph models sounded better than the X-series. I'll have to give the XA's a listen"

XA is one notch above Aleph, it keeps all the good stuffs in Aleph but with better bass, image and treble. The difference is not trivia so that no A/B comparison is needed to appreciate the improvement.

"The XA series does run a higher Class A bias though, correct?"

No ! The total bias current is even higher but rail voltage is much lower.
