I have a 7 year old RAM modded Esoteric DV-60 that now has frequent trouble reading both CDs and SACDs (plays disc freezes up in middle of disc and does not resume play). I've eliminated power cords,mats, and the discs themselves as causes.Believe transport is going bad.RAM is out of business.Just moved to Denver area and would like a competent local tech to check it out.Any members here know of one?
