There are two setups in the house. This one is the "commercial" one (the other is my DIY setup).

Starting with the speakers; MonoPulse 42A

These are created by a small british company; http://www.monopulse.co.uk/ - superb value for money. This is a two way construction with a 8" woofer and a tweeter.

Next out is the amplifier; KingRex QS1. This class-t amplifier is also a steal ;) excellent soundstage, resolution and bass extension. Highly recommended.

Taking a look under the hood...

Benchmark DAC1 is used as a preamp and dac

and finally a SqueezeBox Duet is feeding the benchmark.
