Have had my share of doubts too with the A200s and DP900/DC901 which during month 3-6 of use ~ Kinda sluggish and veiled at times (roller coasting). Was thinking hard whether it was my new Siltech PCs and ICs breaking-in or was it the actual inherent Accuphase sound that I'm hearing.
Even crossed my mind at times whether to switch to other amps and cdp while they were still fairly new. Luckily more patience pays off, north of 6mths of use, then realized they were keeper. Speed, rhythm, timing, clarity, delineation all picked up to where I had hoped for, whilst still staying true to Accuphase renown musicality. What I learned was that from new ~ like butterfly, they took quite a while to totally break free from its cocoon ~ which at the end was well worth it.
*Also noticed them to take at least a couple hours upon start up to sound their best. I usually turned them on at around 9pm after dinner, at 12am they started sounding good, and usually at 3-4am I have a hard time dragging my *ss off to sleep! Lol
Good to hear that that it's finally working well for you too! Happy listening buddy..
