In looking at the display, even though it is not turned on, it looked pretty familiar to me. Since I just happened to have the owners manual for the Sherwood/Newcastle P-965 on my hard drive I compared their illustration of the 965's display with what you can see in Scott's picture. Sure enough, they appear very similar if not the same. On to the S/N site where they have a very nice picture
of the rear of the P-965. Yep, the same layout although the 990 has more stuff like XLR, DVI etc. but the layout is identical expect for the additional ins and outs. I think it is a pretty safe bet these two units are built off of the same chassis. But, the 990 would appear to have more features at about the same street cost as the P-965.
