Thank you HiFi Jeff. The preamp is a Rogue Audio 99 Super Magnum. The CD is a Swedish brand, Primare. Superb integration between the M/L sub and the Omegas. As far as the two questions re the speakers - I believe moving the drivers closer together is an improvement in performance Louis discovered after doing quite a bit more work with 1.5 way RS5 speakers subsequent to building the outlaws in Jazz's post. A wider baffle will reflect/reinforce lower frequencies rather than letting them radiate around the enclosure as a narrower baffle would. So the wider baffle along with the dual drivers produces more body, weight, presence, energy (whatever you want to call it) in the lower midrange/upper bass. In my many conversations/emails with Louis I commented that a frustration I had with my Martin Logans is they seemed "thin", the left hand of the piano player never had enough impact. I assume that was the effect of the crossover and its job of mating a dynamic woofer with a stat panel. Louis's immediate response was - 1.5 RS5's and wide baffle.
Shifting subjects I would like to say thank you to some folks that helped me make the amplifier decision after I had made the speaker decision. Canada Rob - thank you for introducing Wolf Ear Audio, Andrew Rintoul and his Kitoki to the Omega audio circle. Thank you Andrew for organizing the Kitoki tour. And thank you Kitoki tour participants for sharing your impressions and observations. Without all of this I would not be basking in the musical glory that is the combination of Super 3 High Output XRS and Wolf Ear Audio Kitoki. Michael
