Stereo, I hope you don't mind me throwing my proverbial audio spanners into the works. I'm a little perplexed as to how the original ethos of simplicity and 'minimal implementation' approach, to maximise potential of eventual outcome can be reconciled with having to link 'extra' boxes together, notwithstanding custom implementation eg a single volume control btwn multiple preamps, and a single clock to coordinate btwn multiple dacs.
It just seems to me that the criticism of signal loss thru multiple components in a passive crossover is one, possible significant, compromise. But surely a total custom set up enhances difficulty in it's own right too. I mean other than cost, there must be SO many downsides to mounting up preamps, volume controls, dacs, clocks etc.
How are you ever going to really be able to make a definitive decision btwn the two configurations you said you'd a-b in a previous post?
You have to remember I'm coming from the viewpoint of eliminating the xover completely in my system with Zu Audio Definitions Mk 4 spkrs, and given the choice I'd never go back to a xover, hearing (actually "NOT" hearing) the benefits of absence of xover in my system.
Just my two Cents.
