No one needs me to detail the strengths of McIntosh equipment, not the least of which is its consistently smooth midrange. But in a system that included the McIntosh C2500 tube preamp ($6500), MEN220 Room Perfect room correction ($4500), MC452 power amp ($8500), MPC1500 power controller ($4500), MCD1100 CD Player ($10,000), and XR100 speakers ($10,000), the tightness and impact of the bass was nothing short of startling. Call it the “Whoa! Factor.” Equally noteworthy was the very warm, large, and all-enveloping presentation.
