Ryder, put the BPT on some symposium roller balls or similar. ie. quality feet. That makes a HUGE improvement. On spikes, things tighen up but can sound hard, on balls, you get lovely top end openess/air. Finally, can't verify improvement as such, but i put my amp closest to the IEC, followed by pre and CDP/digital furthest away/last in chain.
Ryder - my BBT PPC is all oyaide + ERS. Mine does not have bybee as i generally don't like them. My friend on the other hand loves them and has them in his unit. The ERS and Oyaide are the 'big' upgrades in my mind.
hi Lokie, If you mean the black hollow base - don't. Kevin Scott apparently spent a lot of time building these seemingly simple base. i put mine on roller balls then on some wood base to raise them and off carpets. I find they like to 'breathe' and don't work well on any vibration dampening devices e.g. symposium platforms - kills the sound. Some shun mook mpingo on them does wonders too.
I'm in london mate which means small flats - yes, my speaker are less than ideal distance appart - perhaps 7-8 feet at best but it still sounds glorious.
My impression is the IBX is more immediate/lively with better grip whereas the OBX is probably a tad more transparent but more laid back/sanquine. But cables costs more! Kevin prefers the OBX but the market wants IBX.
TubeDistinctions - You're exactly right re the history. Yes it's commercially available and you can contact Anthony directly here. Let him know Clinton says hi. http://www.tubedistinctions.co.uk/soul_mate.htm
I've not managed to hear the vibe+pulse in my own system but others i know have and they say it's better. Personally, the 1 box + remote option swung it for me even if it's just as good. But most importantly, my power amp only works with very specific pre's of which the Soul Mate is one of them.
AudioTekne - i have heard better cables but they cost a lot more and since i use double runs for my external crossovers, it gets v expensive if i start going something more expensive.
