Just landed on Audiogon today. Hope everyone is well. Great thread. Just talking about this. Not sure if it's regret - more had to because of kid safety ha. Actually regret yes.
1st gen Quad ESL 57's - not restored (they were incredible) AKA as totally not safe
2 Marantz 8B's rolled -- no cages
Sonic Frontiers preamp rolled - cage-less
Mod'ed Eico HF81 driven blocks - totally unsafe and shocked myself more that once
Merrill Heirloom rig with a DP6/Koetsu - could barely lift this
All sold in a week 20+ years ago due to kids invading the bat cave. The thought of them grabbing a tube or having any of this even near them scared the heck out of me - especially if their friends whizzed around ran into any of it and the lawsuits started rolling in - lethal. My wife felt the same way - no lock on the door allowed for their well being (?) Not sure what that was all about.
Of all of it, the Merrill rig is what I regret selling the most, There really was no reason to other than I wanted to buy an exotic camera lens.
Gene Rubin set me up a LFD Mistral LE, Apollo CD Player (I think), Spendor S3/5's and an RP3 tt - and that is what I still am using decades later. It's decent mid-fi, however John Coltrane is not standing in front of me any longer.
