A view from over the pond where AZ is not readily available. I am using Matrix and a single run of Hologram with jumpers. Again, what a coincidence, with an Aleph 3 amp, to Living Voice Avatars with a Graaf valve pre. Again I have been using Nordost Red Dawn and I agree they are superficially fast and exciting, but just less musical. The AZ has a richer tonal palette, it makes music more musical, excuse the oxymoron. The Hologram in particular, made as much difference as upgrading my LV speakers from Auditorium to Avatar and the latter are in my view, special speakers. I am awaiting the arrival of my Silver Ref bought off Audiogon.
