Glenn, those N7's are still on ebay at the moment, wonder how much that UK one will go for... I'm confident it will be way more than what I can spend (like 20 bucks or so at the moment, hehe). The TA-E88B's from the same seller (also mint) went both for more than 500€.
Looking at those pics Mirko posted again, I am mesmerized... a fortune in VFET's alone on that first pic... (Wega 4810, TA-4650, TA-5650, TA-8650, TA-E7B, another Wega 4810, Yamaha C-1, TAN-5550, TAN-8550, and Yamaha UC-1)
Can't make out everything on the second pic, but I see a ST-5000, STR-6060, two ST-5950's ?, 2 TAE-8450's, another TAN-8550, ST-A6B, 2 ST-A7B's, TA-E7B, TA-F6B, TA-5650, TA-4650, some WEGA tuner, ESPRIT SE-P900, ST-J88B, TA-E88B, TA-E86B, Wega Lab Zero pre without base, Wega Lab Zero tuner, Wega Lab Zero pre, TA-2650 ?, can't make out most of the stuff underneath and more to the right because the pic is too small and the light is wrong, but I still see a TA-F80 or two, TA-E901 ESPRIT, TA-N901 ESPRIT, some more TA-5650's, a ST-5950 ?
Not counting the stuff you are not showing, and the stuff you have in your setup... (TA-E900, Wega Lab Zero tuner, PS-8750, TA-N7B, Yamaha B-1 and B-2, SCD-777ES...)
Man I could keep going, one has to wonder how much money you have invested in this stuff, you could start your own vintage store...

Or join efforts with some forum members and open a Sony vintage museum!
Btw, prices on vintage gear seem to be going up and up and up, ESPRIT TA-D900 crossover went for 675€... gasp...
