The SPL Performer s900 stereo power amplifier marks the middle of the line and is based on the big SPL Performer s1200 stereo power amp in terms of the selection of components and conceptual design.
This is where sonic greatness meets performance specs that perfectly
match high-resolution but not overly power-hungry speakers of any size.
With an amplifier output of 2 x 370 W (4 Ω) [2 x 420 W (2 Ω); 2 x 200 W (8 Ω)],
it truly has enough reserves to powerfully drive any loudspeaker.The Performer s900 stereo power amplifier is a compact size powerhouse. It excels in exceptional headroom thanks to the SPL VOLTAiR technology and impresses with a detail-rich, vivid, honest and musically outstanding sound.
