Classic Audio Loudspeakers/Atma-Sphere Music Systems/Purist … – Stereophile Magazine

Atma-Sphere’s Ralph Karsten was not in attendance, but his amplifiers were, including his MP1 preamplifiers ($12,100/pair), and MK3.3 Novacron monoblocks ($12,000/pair): 60Wpc; four Russian 6C33 power triodes per channel; class-A, Circlotronic® direct-coupled (OTL) output stage; dual-mono chassis construction; V-Cap copper-foil Teflon coupling capacitors; and Teflon power tube sockets. A Technics SP10 turntable with a Tri-planar 12″ arm and van den Hul The Colibri Signature cartridge ($12,000) performed source duties.

This system was graphically detailed, with a focus on treble and midrange vibrations. The overall sound was expansive, easily filling the large ballroom space. Night on Bald Mountain was a veritable showstopper!

$12000 for a pair of MP-1s…what a bargain.

TWO 15" woofers per cabinet?

Where’s the second woofer, rear-firing?

Crossover must be hairy, with 2 big woofers, then the tweeter and the field coil horn.
