Question for Weiss Dac 501 Owners

I did not respond to this thread back in July, had just moved homes.  In my last home, I had a pretty symmetrical room, and found the DSP function not all that necessary, and perhaps a slight sound quality hit when activating them.  My new room is totally asymmetrical and has some bass issues.  With the DSP I have tamed a boom issue around 100 hz and bumped up the bass in one channel at low frequencies to make up for the other side having a wall closer to it, and bumped up both channels bass in the lowest octave given other room issues.  It works great.  So my conclusion has been it’s nice to have if you need them, and they work nicely.    Very flexible settings with lots of options. 

I have found that the room correction has been most useful—I have a node at 135Hz and it’s amazing to be able to reduce the dB at that frequency.

I tried the headphone equalization with Audeze lcd-3. My first impression is that it makes a pleasant difference.  Will listen more extensively with and without over the next couple of days.  Compared to Yggdrasil A2 the phones are more lively with better upper mids.
