Recently purchased the 990 and am quite happy with it. Lower noise floor, more detail, better imaging and more realistic sounding than my Parasound AVC-1800 that it replaced. Noticed a few Parasound power amp users like myself on this forum. Don't think I will be sending the 990 back. My DVD-As, SACDs, CDs and DVD movies never sounded so good. Have my 990 on Herbie's Audio Lab Tenderfeet and resolution increased again. Wife and children are happy as well. Nice upgrade!
