Thanks to all who have replied. I've had this problem for years, but only with certain DAC's-probably should have mentioned that. I'm not sure why 2 out of 3 DAC's revealed the problem, but the other did not. When I first discovered the problem, I thought I had a bad DAC, but when I recently auditioned the Premate Plus by DEQX and it did the same thing, I knew it must be the transport. I ran an old lens cleaner I found in my CD rack, but it didn't help. I realize the 6 second cleaner of little soft bristles, probably isn't the best and I even hesitated thinking the cleaner may do more harm than help. Even though it hasn't become worse over the years, maybe it's time to install a new laser. Pretty sure I can get one through Pioneer. Missing a single note, every now and then isn't a big deal.
