So, picked up the 751s today - had forgotten how small they are!
Anyway, they're very very almost mint condition, in the original box, with some very hefty stands. Got them home, plugged them into the Onkyo, and I'm pretty amazed by the sound that this system throws out. It's cost me about £400 (excluding various cables and interconnects I had kicking around anyway and my old marantz ki sig cd player). BARGAIN!
So far, whatever the source (internet radio, spotify, CD, DNLA) the sound is awesome - have thrown as much challenging music at it as I can (stereolab, slayer, wu tang, creation rebel, sonic youth, tom waits, diamanda galas, leftfield, faust, coil, wire and so on) and it handles it all superbly. Not missing in bass I would say. Not for this money anyway!
I suspect the onkyo could power something a lot more substantial (not that that's a complaint about the 751s at all!) which leads me on to a question of how careful I need to be with the 751s. I've had it all running pretty damn loud, but just wondering how much stick the 751s can take - anyone got any thoughts on that?
Really keen to try some 752s with this set up now, so keeping an eye out for bargains.
The TDL RTL2s and RTL3s seem to go for not a lot of money - anyone like those?
As is typical, a pair of 751s just went on fleabay for £50, but they weren't in as nice nick as mine, and mine are rosewood, those are black, if that's important to anyone.
Anyway, just goes to show what bargains are available second hand, and thanks to anyone who offered advice here!
BTW - play.com are selling the Onkyo for £249.99! That is a steal.
