A couple of months ago, I had the Universal Truth mod installed on my Denon 2900..
Overall, I am quite pleased--especially with the quality of the workmanship! However, I have a couple of small quibbles related to vocals: Sometimes there is a bit of sibilance, and occasionally, for lack of a better description, they can sound like they are coming out of a tin can.
Is this related to the break-in process, or am I now hearing a more accurate rendition of the recording? I have done some research, and it seems as though the the Black Gates are very slow to settle in?? I currently have bewteen 75 and 100 hours on the unit.
I must restate that overall I am delighted with the mod--especially dynamics and separation/delineation of voices and instruments.
Thanks for all input!
