This amplifier was used for about a year and recently traded in for another model, it has four channels of amplification on tap at 100W per channel -- for a grand total of 400 watts. This amp could be used to bi-amp your speakers, or tri-amp if you already have another stereo amplifier in your system. Furthermore, it can be fitted with optional Linn Aktiv crossover units for even better performance from your Linn speakers. The casework is in excellent condition with no signs of wear. It also has the latest variant of Linn's Dynamik power supply installed. We don't have the original box, but will include two sets of Linn analogue RCA cables.
