Thanks all for your responses and recommendations. I will have time to review them over the holiday weekend. One other potential amp that a friend had brought up that is in the $ range for a lightly used amp - McIntosh MC 152.
@soix - I liked the recommendation on the McCormack but it was for local pickup. The Plinius looks very clean and I bet sounds awesome. I know how much heat my F8 puts out in a smaller audio closet and would be concerned with this in the space. I will look into this factor a bit more.
