Lol - we could do that, but weighing 40kg, it's not something I enjoy carting around too much.... If the MBLs aren't a problematic load for a valve amp, which I suspect they're not, then I think that Jerry would very much enjoy what the Copper amp does, as Tannoys aside, we tend to like a similar sound :)
Jerry, I hear ya, about the amps, and totally get where you're coming from. However, my point was simply that £20k loudspeakers deserve to be driven by a similar calibre of amplification (and I don't just mean 'expensive for expensive's sake'), but where they mullah has been spent in the right places. You know me when it comes to SPPV! ;)
For me, during your amp box-swapping journey, you should be playing more with ones in the £6k range (such as the Chapter), which meet the above criteria, than at the lower end of the scale, which you seem to have done more, that's all. Therefore, why not revisit the £6k amplifier arena, and see what you can come up with there that reflects your usual (carefully considered) lateral thinking and desire to get the biggest bang for your buck - and remind your MBLs what it's like to have some top-notch watts up them! :cool:
Marco.
