Enjoyed reading your review of the CAT JL2 and seeing how your system has developed into something that brings you great satisfaction. Your amps seem to be very revealing of upstream components. On Arthur Salvatore's website (high-endaudio.com) they are listed in the Class A catagory. Have you heard of the Zu Definition loudspeakers? I recently purchased the Zu Druids and am waiting to take delivery. I understand that the Definitions are extremely transparent and dynamic. 6moons did a comprehensive review of them. Look forward to seeing pictures when you are able.
