@upshift Interesting system. Very pleased that the PL700B is still running. Our experience with them back then was that the owner would manage to make them fail pretty much every time. CONGRATS!
The rest of your system sounds fine, and if YOU like it IN YOUR ROOM, you are good to go. I wouild make suggestions, but you didn't ask for any, so...
There is a small shop just over the line in Deerfield on the East side of the street that you migh want to visit. You might have to make an appointment, but I think they are the closest "high-end" shop if you are interested. Audio Center is the name, I think.
I retired and moved from Boca after 49 years there. I just couldn't take it any more. I am in Hobe Sound now, and it reminds me of Boca back then when there were about 20,000 people living there, and only about 10,000 during the off season. Nice town in those days.
Cheers!
