Peeps thank you all.

Mr Widget you know what, I have not flicked the switch to high bias yet, haha, and the weather is getting cooler...will try that this weekend, thank you.

Ooh those Macs sound nice thanks Alan D, will check them out but every time I get an itch to experiment with amps, I see the JC1's sitting there and feel guilty for having wandering eyes, haha! They have been incredible and continue to be, high SPL doesn't faze the SQ etc...or the 4367's for that matter...

Parasound HCA 2205- OK that is really interesting and yes, would kill for some new version JC1's...alas this money system holds me back...
