Thanks!
Yes, that N8000 xover between 077 and horn has had me guessing from day 1, and haven't been able to make up my mind between fixed (op-amp) crossovers, or another DSP/crossover but better performing than the Venu. Not sure my hearing would detect subtle changes in that area, though.
Tri-amp would be possible, but would need (yet) another amp, so kind of want to stay with a two way (overall).
BTW, I think I have the sales slip for the 077 and N8000s upgrades - in 1974 it was like $250 for the set.
The rack was one of those 'gazing at the system requirements' &... 'what-if-?' - moments, so, insanely, it is scratch built.
Pretty similar to original (a bit less wide), of 3/4" walnut veneer and various add'l bits of scrap exotic woods from here and there for the edges, shelves and LOTs of rack bracing, and dual 8" (dead silent) fans in doors in back.
Milling the front edges (almost no parallel edges or planes!) was the toughest bit, otherwise just a long fussy build.
Had I known where to grab a carcasss from I'd sure have done that first, but this was a challenge I could not resist, and I have to say it turned out quite well.
It's sturdy as all get out, though it is a wee bit tight in there, for an 8 channel system; and visually can't be told from one of the real L200 cabs, even sitting side by side.
The 'input' gear - AppleTV, Oppo Bluray player, Motu ADC-USB are all behind the flap of the shelf to the right, plus 70s preamp and sony TT on top (now).
Have been a few neat projects.
