I sold my Bel Canto Ref 1K after 6 months of ownership for the Nuforce MCH-3SE. In my set up and preference, there was no comparison. The Nuforce is a lot more extended and higher resolution from top to bottom, has better bass control (higher damping factor) and a more lively, dynamic presentation compared to the Bel Canto's overly romantic but midrange- centric sonic signature. Still happy with the Nuforce after more than 4yrs. To each his own. Best way is to try both in your own home and set up and make your choice.
Best regards,
