Another update. Well I have been using the SR2's every day from Tuesday to Sunday. Today was all jazz, all day:
1) Charles Mingus - Ah Um
2) Donald Byrd - Byrd's Word
3) Clarence Clemons - Peacemaker
4) Hank Mobley - Peckin' Time
5) Herbie Hancock - Maiden Voyage
6) Freddie Hubbard - Open Sesame and Red Clay
7) Horace Silver - Songs for my Father.
Lots of classics!
The SR2's have tons of bass and great mids.
They are definitely lacking in treble, IMO. I love horn jazz and sometimes they can get a little screechy or piercing, depending on the headphone. That never happened with these. On the other hand, they didn't quite hit some of the high notes that I am used to.
So far, bass and mids are great. Treble is somewhat lacking. I am somewhat unsure about clarity and separation. They didn't seem great at first, but then I had some brain burn-in after a few days and they seemed better. I am now Very curious to compare them against my favourites (Grado GH2's, Focal Elex's and HiFiman HE6se V2's). That will happen closer to next weekend. I am also curious how they would stack up against the CFA Cascades.
I can't see adding any bass boost at this time, but I am curious if the 3D sound effect will make any difference at all. Will also toss them on my Violectric V220 and Little Dot MK9 this week. Just about tweaking this week and then start comparing headphones next weekend.
So far, they seem like a nice set, but time will tell how nice.
