The C4200 is essentially the same Akurate 4200 amp that had a different namesake. So similarly, the C4200 puts out 200W into four channels (in 4 ohm. 111W in 8 ohm), has the same advance technology like their Dynamik Switch Mode Power Supply (SMPS) technology which provides the clean, superbly neutral and ultra fast sound its come to be known for. The amp can be configured with Aktiv cards if you have a pair of Linn speakers that needs to be run with Linn Aktiv amps. So the four channel can either be configured (with Aktiv cards installed) to put out two channels in bass mode and two channels in the mid-high mode or as is now (without the Aktiv cards) in a bi-amp mode.
Cosmetically, the unit looks good. Minor scuff marks here and there but nothing major. We don’t have the original box but can securely pack it for safe shipping. The amp has the more conventional five way speaker binding posts so it can be used with banana or spades or bare wire. Manual is available online.
