Dsp !
Definitely DSP !
It Would be Great to have some eq filters, and ( PLEASE ) delay adjustments.
I think that If You are a real Audiophile, You just dont care about the loook of the equipment, because the real important stuff is How It Sounds
In my experience, I´ve found that one of the most important adjustments ( nobody does it ) is the time alignment between speakers, and with some parametric eq filters, and delay, You can make the perfect calibration of the sound system.
I have installed HT´s with an extra DSP processor just for the sub´s
( The system was B&W Silver Signature & Kinergetics research amp´s, the DSP I used is the BSS Omnidrive Compact ) and believe me, sounds just beautiful when the arrival times of the sound waves hit your ears just in the same time, in the right phase.
