    James I emailed you yesterday about paying for the psu and to say you are welcome to keep longer if you wish. I'm in no hurry to get them back. Just to say I still have your Colin wonfir amp here to return and if/when I do come up I'll bring my Bakoon for you to hear.

    Can't wait to hear your amp Paul! Got a small revision to your PSU to make. Parts on order, nothing major, just an afterthought, ready maybe Wednesday.

    I have had the field coils playing in my listening room for a few weeks now, no longer in the open boxes but in my quarter waves. So little room and close to the back and side walls. For those that were talking about hum, well there is none at all, dead silent. They sound great, better top end than the Lii audio crystal 10 and maybe more realistic bass, what I mean is, with many speakers they are designed to give more bass than is realistic for people's appetite for bass. These don't just do bass all the time. Boris blank etc lots of deep bass that is associated with this kind of music and more subtle detailed bass on most everything else. I have got around to trying different voltages or output impedance yet, will get around to that once I've got familiar with them.

    Hi Paul, thanks for the thread, I'm sure it's been interesting for many. They're certainly a subject I'm unfamiliar with, but having heard some of the Lii Audio range I expect you're listening to music with quite a wide grin on your face.

    Well done to James too, with the power supply.

    Thanks for the kind words, but TBH given the august standards on this forum, I am nothing more than an amateur dabbler, albeit a happy one!
    The thread runs slowly, which is as I would expect. Pretty niche stuff here. I suspect Paul will still be watching
