thank you for your comments. Let me try to answer some questions.

GA: I had my Grands since about 16 years. I also have the original schematics of the electronics, as well as the software codes to run them. I also have the Goldmund Reference Turntable you mentioned, one of the last 25 made, also including original wooden crates, schematics etc.

FR: I have not heard anything like it yet, so it's hard to describe. It is the only system I ever heard which can sometimes make you believe that the real thing is in front of you. You are welcome to give them a listen if you like. Maybe the fact that I have invested north of the retail price of a Magnepan 30.7 just into keeping the big Apogees going, is an indication of how much I value them. 

SH: Yes, it is a special acoustic ceiling and helps the system along by a long way. The room has a nice balance between damp and live sound.

PA: Keep enjoying them :-)
