Instead on just another linear ( yawn!) why not apply the considerable Elecraft talents to developing a non linear highly efficient ( and light) all mode amp via the path described in this month's QEX?

There was an excessive delay. In the process, additional performance enhancements were made to the third party virtual radios in Win4K3Suite.

My input is as follows: (1) 1500W+ output, key down; (2) light weight (30 lbs or less); if the 30lbs is not doable in a single unit, then the power supply could be put in a separate box; (3) capability to support two transceivers, much like the current Yaesu Quadra; and (4) full computer control of amp and transceiver(s) I'll leave the detailed suggestions to those much more qualified than I to make. Finally, I will purchase one at Dayton if it is available, sight unseen, based on the Elecraft history of producing high quality products, and most importantly, updating and supporting them throughout their life cycle. Thanks Elecraft for all that you do.
