The seller got in contact just yesterday - two left - and now bought by me. :)
There is another seller on ebay but he's shifting the old ones. He does have a pair of the new model 200ASC but he doesn't want to sell them unless you pay a lot more. He also wants more than the seller we used for just the old ones.
There is also a guy on diyaudio (search "200ASC" long thread towards end). He'll take about the same amount but he hasn't confirmed if they are old or new version (new version has two tranducers of the same size and has the layout on icepower website).
My 140's are in exceptional condition apart from one missing strap but they look better without any straps IMHO. I paid just £120 with the floor stands!
Pentas still rock. I drilled a small breather hole in the bottom and the amps no longer overheat at full power. The bottom is actually air-tight without a hole to allow for effective passive cooling. The sound is still to die for. I'd love to have them against a pair of Beolab 9 and 5's for a comparison....
I wouldn't use any amps but icepower as they are the best on the market hands down. The hypex are cheap and unrefined. The 200 have all the automatic shutdown and power onboard. The 250's dont have LED, auto standby etc. I heard they have a bit more kick but don't sound as nice as the 500's. The 250's could also damage the mid-range on the Pentas as can kick over 150W short-term (close to 200W @ 8ohm) and they'd certainly blow something on the 140's as the overheat circuit on the speakers wouldn't catch this sort of short term abuse.
I'll get some pictures up of my 140 conversion next week. Where did you get the little white stands for the 200ASC board from btw?
