Maybe.
I built the LX-521's above at the end of 2014. They've been in storage for the last four years due to room size constraints. A few weeks ago I combined the woofer enclosure with the LX mini (the plumbing) which is called the LX Studio. Much better bass. I decided to try the full LX-521.4 setup, though I've serious doubts they'll perform well in such a small room. If they don't I'll go back to the LX Studio configuration for now.
Either way I'd always intended to move the amps out of the equipment rack to shorten the speaker wires. The longest run was 30'. I've the AHB2 on low gain and have modified the Okto DAC8 DSP to output a bit over +24dBu, ~12V at max level. That with the Canare Star Quad should be a walk in the park for a 30' balanced line level run.
