I nominate the Slim Devices (Logitech) Transporter



It sounds better than any CD player at the price (and a few that cost more including the Audionet ART V2 which I sold).

It's also a very versatile machine with AES/BNC/Coax/Optical digital inputs and outputs. It's even possible to use these inputs and outputs as an effects loop with a Behringer DEQ or such like.

It plays 24/96 (stunning).

And then there's all those internet radio stations.

Best of all, each time I upgrade my amp or speakers, the Transporter just steps up to the plate. What an amazing machine.
