Thanks! I've also been experimenting a little with tips, but really, I need to wait for the SB's to fully run in first.
As for the selecting the SB's over the SS, I'm glad I had a second chance to audition them - on my first trip to Akihabara, I was seduced by the more forward mid and upper-bass of the SS and would probably have bought them. However there was something about the SS vs SB nagging me at the back of my mind. But since I was already a bit disoriented with listening so many different earphones that day (SC, SS, SB, e-Q7, Fx-700, CK100, IE7, IE8, Monster etc) and since I also knew that I would be coming back in a couple of days, I didn't buy them that day. Then on my next trip I concentrated only on the e-Q7, SS & SB. Loved the e-Q7's but in the end, for me, it was no match for the FAD's. So then I spent the next 45mins listening only to the SS & SB and finally decided on the SB for the reasons mentioned in my earlier post.
I'm glad I went with my gut. Had I done what you did and audition a lot of 'phones - my original intent - I would have had your problem.
How were the FX700s? They were not out when I was there. I wanted to try the Pioneers as well, but didn't get around to it.
