ericp10, How do you find the sub-bass, bass and mid-bass on the CKM-500? How does the bass compare to the ASG-1? I like these very much, because I also own three pairs of AT headphones, see my sig. I love the vocals on all Audio Technica's that I own. I think the CKM-500 is overdone, drowning out a lot of the purity in the mids and highs, and the mid-bass hump is affecting the quality of sound in the vocals. Using my parametric EQ in jRiver, I reduced 30hz -4db, 60hz -4db, and 125hz by -4db. Initially I like this a lot better than the stock CKM-500 sound. The mids are very good, and the sparkle in the highs lovely. I just can't take the bass on these with songs that already have enough bass. I am getting very good instrament separation, but crossfeed settings in jRiver Media Center 16 contributes to that. For me the soundstage is big but lacks 3D depth, good height, instraments can be outside my shoulders for width on a lot of tracks....again crossfeed really helps here. Loreena Mckinnet has a lot of different string instraments, lowland pipes, and exotic drums, very good tone on all, IMO!. Carolina Chocolate Drops are fun. Really like the clarity with the reduced bass above. I am using the custom Aurisonics slicone tips from Dale, for the best sound, with the deep insertion I could'nt take the basshead sound before the adjustments! So, for the price, and after three days of listening, they are in the mix with my favorite IEM's and AT headphones. The reason I purchased them is to see if the Audio Technica sound was there, compared to my headphones, and......I can say the lush vocals are there in all their glory!
EQ settings are trial and error, but so far I like the CKM-500 with the reduced settings......I would like to see a FR graph for them, to see if my ears are telling me what I hear in the low end! When I use parametric EQ, I try to get the same amount of bass that I hear in my main system that has two subwoofers....those are set using my Antimode 8033, and the Audyssey in my reciever, so I know what proper bass levels sound!
