Beautiful and good amplifier Denon PMA 920 This is still old-fashioned with toroidal transformer. Built like... a tank... see the specifications, high output power 2 x 115 watts at 8 ohms, Can also be used as (pre) amplifier and power amplifier. The tone control and filters etc. can all be used, so you can even adjust vinyl in frequency range. CD direct input and pre-out to power stage. Fully class A by bias control via an opto isolator at lower volume  Oversized screened round transformer and high capp capacitors.  Very nice phono input which is switchable in MM/MC. Amplifier is in perfect condition and sounds warm and musical, as we may expect from the older Denons. Specifications Power output: 115 watts per channel into 8Ω (stereo) Dimensions: 434 x 162 x 392 mm Weight: 11kg
