Joesph,
Is there any reason why a good parametric wouldn't be a better fit? 31band EQs are really yesterday's news.

dbx makes a great EQ. I also have a number of them sitting on a shelf, not used since I went digital. Send me a PM if interested.

The 4400 isn't a single space unit.  If you're absolutely painted into a 1u corner, there really aren't many (analog) options better than the dbx 131s.

For what are you using these eq's?  How high is "high quality"?

As for mono 1/3rd octave EQ's, Klark Teknik DN300's are nice, but they're 2u high.  The same applies for the dbx 2031 and the Ashly GQX3101.

I haven't used a 31band EQ analog or digital in 5 years. 1/3 octave filters rarely fit my needs when commissioning or teching.

I'll tell you what a 31-band EQ is good for.  Ear training.  Use it to learn about what happens when you adjust something.  You should actually hear a difference.  If you can't detect a difference with a change of ANY of the 31 bands, then your source material needs to change.  Manipulating pink noise and sine test tones (at low levels, of course) will train your ears to spot things that are 'out of whack'.  That is a technical term.

In the now world of available decent quality speakers in general, and decent quality powered speakers specifically, a 31-band EQ is really of no use.

Yeah that's why the Rivage has one per channel (choice of two graphics actually).  It's a tool like anything.  Some use it to draw smiley faces others to create sonic masterpieces.

Thanks again for all your ideas! My main use for the eq would be to ring out each room I use the system in and only for cut. I have all speaker filters set in the crown amps to make the speakers flat it's just venues emphasize some frequencies so useing an RTA / FFT I'd like to flatten the room without going crazy using too much treatment hanging from lighting truss.
I would like to keep all units in signal chain the best quality I can get as I paid a lot of attention to the rest of the system including the source of actual vinyl barring any snake oil cables or correction processors.  Thanks joey
