Have seen the Lyra Connoisseur Phono stages come up for sale once in a great while.
Never seen a Mares Connoisseur 2.0 Phono up for sale!

Rex,
AV Options uses Cryogenics International (Charles Beresford) for Deep-Cryo - it's on their website. In my experience Charles is the best in the business.

The Crosby Audio Works mods of Spectral gear were excellent and way ahead of the already good at the time Spectral gear. Used to have a full system, regret selling it off. Where is that gear on the AudioGraffit site? Can't find it.
Terry is a long time friend and one of the best people I've ever met in Audio. A gentleman and a professional who knows audio and music and how to communicate effectively that knowledge. Overture post Terry on the other hand....
