Any update on Mark Levinson 5000 reliability?

i don’t think you can measure performance by the pound. Both the Benchmark AHB2 amp (13 lbs) and the Van Alstine monoblocks (17 lb each) get excellent reviews and their gear is noted as very reliable. FWIW.

Understood Patrick. I would not assume that either... just that the ML is impressive compared to the Ayre in stature. 

There are so many better, less problematic units out there for similar or less monies 

why put that reliability thing to chance as I stated with so many quality alternative's

I've been using ML 5802 for over a year, no technical issues at all, the sound is rather analytical but paired with Tannoy Ardens gets me the sound I want.

Good luck!

Thanks, Sergey... I can buy one for close to dealer cost (like new) from a dealer friend. Most recommendations being made are for integrated amps that would cost $3-4k more. In mint condition, this seems like a great integrated amp for $5k. 

Mark Levinson amps sound mostly very good, but it is very hard and expensive to recap or service (and you have to do full recap for your amp every 20-30 regardless of brand). I used to own ML 23.5 and ML 333. The cost of servicing for those amps are any where between $2400 and $2600 not including shipping from and to the service center.
