Best amps to use for the Dali megalines

I'm running Merrill Audio VERITAS mono amps on the bottom & a PS Audio BHK Signature 250 amp on the top with a asi-tek 'transformed' Behringer DCX2496 crossovered at 700hz at 48db brining them together.The sound going from my Megalines is by far best I have have/heard in my 30 years of audio. So sweet sounding with such spooky imaging it's scary! You cannot beat a floor to ceiling dipole ribbon period. I will be enjoying these for many many years to come.

Hi,

Four identical monoblocks drive our MegaLine III loudspeakers.

Best,

Sam

Oh, forgot...congrats on your acquisition -- I wish you innumerable hours of musical bliss.  :-)

Hi there

Thanks to everyone for their valued opinions and thanks c1ferrari - I am truly blessed!. I will probably put the ARC ref 750's on the dipole ribbons, and with the TAD active crossover I am hoping that it is less critical to have 4 identical monoblock's (can't afford another set of 750's anyway, first set nearly ruined me!) so was considering the Jeff Rowland 825 stereo amp which seems to have good write-ups and comments. Any thoughts? 
PS - which cables in order of importance would you spend more money on, power cables, interconnects or speaker cables? Would appreciate any opnions or feedback.

I have generally agreed with  Transparent Audio's hierarchy of cable importance; first source to pre, next speaker cable, then pre to amp. I think power cords are the most unpredictable.
