Near enough the same for me right now tbh, Mango / local, Ultimate, DAC 92, gain 1, analogue past 12 (I can't do full pelt, way too loud, even with DSD), DSD leveling disabled (I've got volume variance in my lib so just adjust per album), D1.
EXN, and plus, is / are superb IMO. Rocky ride though, EXN I had done first and took a fair while to settle in, plus mod I've found the same but maybe slightly less play time. Plus mod on top kind of felt like it put it back a step but I don't think that now. Both required what I'd say is lengthy break in to sound top notch. I tend not to listen too much during break in, check in for a few minutes now and again and just leave it on loop. I've not listened to it much since getting plus mod (EXN I put many hours on), not because I didn't want to, just other things going on, plenty of play time out of ear and a battery recycle. Just put it in now after listening to a mege bucks HP setup most of the day and and wow factor is definitely still there, I guess that says something about it (in this case in particular, paired with Storm / SS)...
Sound differences, different quality of player IMO. Doesn't loose the house sound but improves it top to bottom. If I listed what I thought was better than stock, it would come off as a load of hyperbole, so I won't. It's not a case of just "different", it's definitely "improved".
With Storm it's perfect pairing for me, I'd be very surprised if anything came along soon that could out do it. It'll happen one day no doubt but until then, 11/10 all day every day, it never fails to impress.
Hope this is somewhat helpful. Just one guys opinion though so...
@gentzen, where you located (roughly)?
