It's a shame these never got any hype. Compared to my Audio-Technica IM70s, these are more bass-heavy with an ample amount of sub and mid-bass. Soundstage is about the same on both. With certain eartips the C560 has a bit of a treble peak like the CKM500 but not as sibilant.
I don't know where you can buy Denon's stock eartips as I lost one. The Audio-Technica tips are very similar but softer and not as bulbous. If I recall, treble is a tad rolled-off with AT's tips. Phillips SHE3590 tips are great - the treble is thicker-sounding a bit like the CKM500 but not as congested.
I bought some wide-bore tips today and the soundstage becomes huge and has a bit more depth. The sub and mid-bass do become a bit bloated so I would suggest toning them down with EQ.
