This is so funny! Today I met with Vorlon1 and HiFlight to compare three (one of which was in two configurations) new portable amps with some of our standbys. One of the new ones was an stock D1 and a modded D1 (op-amps changed). The two other portable amps were a production Xin Reference an an iBasso P1. I will post my thoughts on the 26 portable amp but I will say that there is a new "Numero 1" and that the iBasso D1 once again demonstrated to me how good it is. I posted in another thread that I thought the D1 was as good as the SR71, well the modded iBasso D1 is IMO better. You wil have to read the post on the 26 (now 28 amp thread).
Anyways, I tried three full size cans out of the D1: HD600 w/ a Revelation Audio Cable, HD580 w/ its stock cable, and a PROline 2500. I agree with you, IMO the PROline 2500 was the best sounding out of the D1.

Why I have not idea.

BTW, to me the best op-amp on the D1 amp section was either the 2111 or the LT 6241HV (same as the one Dr. Xin uses on his amps). Ron (HiFlight) did not have the 8397 for me to put on the buffer so my D1 still has the 5532's. I will not say that the new op-amps make a night and day difference, but the soundstage is much wider now and I find that it is easier to distinguish the instruments.
