Audio Research CD players were never held in high regard vs Esoteric/MSB/DCS/T+A/Gryphon and plenty of others. Matter of fact the "8" was known to have plenty of issues.
Sorry to be disagreeable. I owned the CD-8 for about 9 years. It gave me great service. I since swapped up to the CD-9SE and it has been totally reliable. I haven't tried the DAC side of the house yet, but many forum members have posted complimentary compliments about the CD-9 DAC.
Not having heard the other players listed in your post, I can make no comment.
