Bad in Passive Mode, but can't wait to take that XO out of the Equation!
REPEAT, TEMPORARY UNTIL I PURCHASE A SNAXO 362 AND SC WITH THE BURNDY GOING FROM THE SC TO THE SNAXO, THEN THE SNAXO WILL DELIVER THE SIGNALS TO THE REAR OF THE BRIKS THREE WAY SPEAKER.
HENCE, ELIMINATING THAT CROSSOVER SHOWN ABOVE!
Allante, have you thought of trying active tri-amping with a cheaper non-Naim active crossover to see if better than the passive tri-amping, to then go full hog with SNaxo when funds allow?
As I mentioned in my last post, Behringer DCX2496 is said to be very good, and it is surprisingly cheap, this side of the Atlantic at least. There are plenty of others as well, though some have better reputations than others.
By the way if you do, it is generally considered wise to protect the tweeter at least, and possibly the mid, with a capacitor providing roll-off starting an octave or two lower than the crossover frequency used, in order to protect against switch-on thump if the amp doesn't have time delay relays, and common power amp faults such as low level DC on the output, that could easily destroy the sensitive high frequency drivers. That said, I've no idea if that is necessary or commonly done with Naim amps (it is nothing to do with what active XO is used).
