Any recent experiences with the Mark levinson 512

Gnomus, thanks very much for your excellent post. I have a Meridian 808.2 and was thinking of making the move to the 512 instead of possibly upgrading to the 808.3 because of cost and the fact that I have always been a Levinson user since the mid 80's. Also, this would give me an all ML front end along with the 326S and 433.
After having several conversations and reading some older posts, I like you have concerns.
Thanks again for your input

I would like to thank both of you gentleman for your enlightened remarks, however I think for the time being I will stay put with my Meridian 808.2. After much thought I just do not feel comfortable with the current Levinson situation. They have lost so many talented people, moved operations countless times, no longer do their own service work and it appears they have had a diminishing dealer base. I have been a loyal Levinson customer since the mid 80s but will take a wait and see approach before making this change. Many thanks, Ron
