Ayre V5X, Sim Moon W5 vs. BC-28.

I have pretty much made my mind to buy a BC-28 next time one comes up on the 'Gon. This based on archives and reviews and I know I can always resell if I am not satisfied. You know, buy and try in your own system. The problem is, this amp has not shown up in some time now on the used market here and in the mean time I have been considering these other fine SS amps.
So, if you have experience with the Sim or the Ayre (or the BC 28 for that matter) will you please share it with me?
Especially if you can compare them to the BC.
My music tastes run mostly to female vocalists in blues jazz and pop/rock veins. I also like to rock to Allman brothers and such at times.
My system is: GMA Europas, Theta Jade and Birdland odeon AG run straight into power section of Nad C370 with Audio Magic cableing.
Thanks, Scott
