So I had the SA1s on the pink noise machine (my PC) for 12 hours or so, with the silver ports (the treble-focused ports) and I just had a 40-minute dog walking listen with them. They sound a little harsh to me, and I had them on VIVA Mach Bass, to get enough bass out of them (which I would never use with the S4s). I also have moved to the Sony hybrid large (light blue), because I just did not like any of the Sleek OEM silicones.
I have to say there may be a very good IEM lurking in that wood body, but so far, it's not shown it's face. Not that they are poor, because that's not the case. They seem a little grainy, and again, there is a sibilance issue for me on many tracks, not all. They sounded very good with classical, for example.
I am going to sit down tonight after dinner and do some more head to head listening with the S4s using the S9. I just don't think the SA1s match up well with the Amp3 because the Amp3 has no EQ, and only certain phones can bring out its fantastic SQ, such as the S4 and the Grado SR-80 both do for me.
No matter, I want to give the SA1 a fair shake, and also will continue to let it burn in when not listening.
I also am going to try a pair of Complys with the SA1s, as well as the bass-oriented port (which is black with the newer version of the phone, both ports used to be silver).
