Well, I've had the Hemptones for about a week now. I've made some changes during that week and things are just now falling into place. I had an acquaintance of mine send me a chip amp (gainclone type of thing, I don't know many details on the actual design) to play with as well, so that is in the system right now with my Arcam integrated running as a pre-amp only.
I have the Omegas crossed over at 80hz to my infinite baffle subwoofer. I originally was hearing a gap as if the speakers were not blending well with the subs and so I ran the speakers full range for a while with the sub crossed over low and filling in the bottom end. After some discussions on another forum, I decided I need to recalibrate the stereo and not rely on setting the sub level by ear. So I calibrated the level of the subs relative to the mains with an SPL meter, crossing over the speakers at 80hz again. I was way off on the sub level and with it set right, things really snapped into place.
I would guess there are probably about 30 hours on the Omegas at this point so they are definitely still breaking in, but since I got the stereo recalibrated, things are really clicking now. The sound I'm hearing is VERY emotional and full of energy. On melancholy tunes, like the new James Blunt CD the system is very emotionally involving and on more energetic tunes like Jason Mraz and Dave Matthews, they demand that you get up and groove to the tunes.
I can only imagine how things are going to improve as I continue to tweak things like speaker placement and toe-in, add some room treatments, and the speakers continue to break in, but even right now, this is the most emotional system I've ever owned.
