Matti has build his own preamplifier and loudspeakers. Before going active Matti had passive filters and the bass were corrected
with an equlizer to adapt to the room response.
Matti has now invested in a set of the big Chassis 1503 to power his loudspeakers.
He will not be short of headroom for the drivers.
The preamplifier is passive, fully balanced and floating from ground. The preamplifier has a 24-step resistor network volume control.
RIAA input for both MM and MC of single shunt type. All inputs are switched via relays and there are 2 balanced,
2 singled-ended and 2 RIAA MC/MM inputs.
