Is DSP room correction worth it with a high end analog system?

Depends what you are doing. :) My hero, Floyd Toole, and I agree on the principle that doing too much EQ makes you wonder why you bought those particular speakers in the first place.

Where EQ really shines is in the bass, and subwoofer integration, and there the effects can be pure glory if done right. 

If you have a high-end 2 channel system the place to start is with excellent room treatment.  Then think about DSP

Room correction is not a cure all. Good hi-fi systems have been in operation long before room correction was possible. Does every system need room correction? I think no but things can always be improved...in most cases. 

Audition the DSPeaker Anti-Mode 2.0 and see if it works for your system.  It did for mine.

It is not the price of electronic components so much that give an Hi-FI experience...

It is acoustic....

The electronic component of Hi-FI is already mature for decades...

Acoustic is completely underestimated in small room ....

Acoustic passive material treatment....

 Especially Acoustic mechanical active control with Helmholtz method...

 It is my experience...

A dedicated room is the only  necessary luxury in audio, not the price of the amplifier 

Everyone knows the more complicated the circuit the better it measures. The more manipulated the signal the better it measures. And the one sure way to make analog measure better is to digitize it.

So by all means if you want to measure stuff then digitize the crap out of it, stand back, and gaze with all your measurebat- er friends at the glorious beauty of your, whatever you call it. Applaud yourselves at turning music into something only an audiophile could love.
