High End Monitoring Controllers - Reverb Balances

Sorry if I'm confused, but when you say, "It has 16x D/A converter chips"  are you talking about the Apogee DA16X which has 16 channels, or saying the  Mini DAC uses the DA16X's  chips? 

For me it boils down to the entire chain.  DAC, monitor controller, amp, speakers, room, ears.   I used a Apogee Mini DAC as my DAC/Monitor controller for quite a few years.  It was fine.  However when I finally added a Coleman M3PH MkII I was blown away by the clarity I was missing.  I needed the Coleman for a few reasons (source switching, speaker switching....) and I was a little depressed at the cost.  However after I heard the difference in the audio path I wish I had picked it up years ago.  Once I heard it - I would have been willing to pay 2x the price.  It is a solid unit, and for me was astonishing how good it is.  For me personally the Coleman now represents something I'd never part with.  

Don't get me wrong - the Apogee Mini Dac is solid - but its volume control sucks compared to the Coleman at low levels (left right balance is not maintained).  To my ears it also lacks the audio path clarity that I get with the Coleman.  For a DAC only it is solid - but all I have to compare it to is my DA-16x.

However I'm not sure I was unable to hear revert tails with the Apogee Mini DAC.  It worked fine for me.  I've not heard the Presounous Central Station so I suppose it could be possible that its converters and analog section messes things up to the point that you are having trouble.  With all gear if possible get your hands on what you think will solve the problem and listen to it in your room with your setup.

I do lean on headphones to check reverb balance - but I'd be fine if all I had were my speakers.  I'd probably miss a little on the side of too much verb if only using speakers; but I know that about my ears/room so I tend to automatically compensate now.

One thing you might want to try is messing with speaker toe-in and placement.  I know you paid money for room setup/treatment but I'd still mess around a little to find what works for you.  Listening to some reference material move the speakers around a little and see if you can get yourself a better phantom center image.  I did this with the help of a friend and a few 2x6's so I could move the speakers easily a few inches off their heavy sand filled stands.  Messing with the toe-in for me presented a much better phantom center that had depth and height.  Something you might try anyway.  If you can't get things to a point where you hear reverb with source material then I'd start looking at other items in your chain; DAC, monitor controller, amp.

Busy today, I had to jump ahead and pass by the other posts, but can say this. I had the Adam A7X's, and what you're looking for is in higher end monitor. When I got the Avantone Abbey (3 way 400 W.) the mix was so transparent I stopped hearing the speakers because they vanished and only heard the mix. Good luck.

Forgot to ask, which reverb's you're using. Lexicons are muddy and a little hazy, with a push in the low end, that's their sound.  That makes vocals more charming but a little opaque.

The Seventh Heaven Bricasti plug does a better job of sounding clean. Some folks still like the Altiverb or Exponential if they like clarity in their reverbs.

I haven't tried the Slate verb suite, but if they keep adding on plugs like the Distressor, I may have to try their monthly package when I get back to work on new material.

Take a look at the NOS controllers, have the features you want or half the price.

To me that (65") is a bit wide for near-fields.  However keep in mind - I'm not a pro - so my experience could be completely wrong!  I've used NS10s for years (not my only monitors).  While I never get excited to hear them, I do find them useful for balance decisions and they work well for me.  I find them easy to hear reverb with.  In my smallish room at 65" I'd be sunk however.  I need them at 36" or less.  I'd say even those Adam7s could use to be closer.  My room sucks,  so I just can't allow that much room sound to compete at a listening position of >= 65".  I'd for sure play with putting them closer and just see what you think/hear.  It could be your pro that setup the room likes things way differently than you do.

Far be it for me to dissuade anybody from buying new monitors, DAC, or monitor controller.  But I'd think you would be able to get what you need with the NS10s - assuming you put them a little closer than 65" - but then again perhaps your room is super awesome and huge.  I've never had any luck going much over 30 or everything just becomes unfocused and super hard for me to figure out.

65" seems wide to me too. I measured mine last night and I'm at 50". No science behind my placement other than an equilateral triangle to the listening position.
