tooblue,
With those extra armwands, I would bypass the Prime Signature and go for the Avenger. There are even some used Avengers on Audiomart. I've owned the Prime and then went to an Avenger, and everything opened up - clarity, soundstage, blacker backgrounds, realism. I was pretty surprised actually. The extra armwands would seem like a good move on the Avenger rather than the Prime Sig. Great options too have though. Mat has always been a true gentleman when I've spoken with him and the rest of the VPI team has been a pleasure to work with. Many dislike the streamlining of the company and many didn't like all the iterations and variations that Harry had in his bespoke offerings. It is hard to please everyone but seems some of those bespoke offerings are available in their Reference Avenger line.
