Jeff, do you use the equalizer all the time? I'm assuming you use it to correct a room deficiency? Or is it on a per musical selection basis?
I only switch it in on records I love that sound lousy. The little bit of a bump in my room was easily corrected with the descent i controls and careful subwoofer placement.
The Massive definitely injects a bit of overall warmth to the presentation and a slight lack of ultimate resolution, but on a lot of crappy rock recordings from the 70's (which I have a lot of...) where you love the music but wish you could clean up the sound a little bit, it's a trade I'll happily make every time.
Another point about the Manley that is so awesome is that many times the difference between a $500 "Hot Stamper" and a $12 record store find (or even a $3 record store find) is a db or two here or there.
Granted the Massive can not fix compression, but even in an overly compressed recording the sonic signature of the Massive gives those records and CD's a more pleasing overall sound, at least to me.
Perfect records, I leave it switched out of the system. With my ACT2, I used to use the External Processor Loop and with the Burmester, I just use the tape monitor.
Even some of the recent remasters of many of our favorite recordings sound a little off to me, often too hot, but the surfaces are clean and quiet. Again, this is a simple fix and with the mastering version having resettable click stops, you can drop a little card or post it into the album jacket and go back to where you were in a jiffy.
So, when people are spending big bucks on really rare records, this can be a great answer for someone who just enjoys music and doesn't really require the collectable aspect of vinyl.
Of all the tweaks I've tried, this one is by far the most useful on a daily basis. I'm even going as far as to "remaster" some of my favorites on LP and burn them to CD for use in the Sooloos and it's worked out really well.
