Boulder 866 Integrated Amp Review

January 17, 2021 § Leave a comment


 The analog and digital version certainly isn’t inexpensive at $14,450, but it’s a game-set-match component, just add speakers. The 866 Integrated looks really nice on my desk sitting next to my iMac and my headphone stand. The metal chassis is 100% Boulder, making it impossible to misidentify this amp as that from another company. The fit and finish are second to none. When it comes to sound quality, the main reason we are all into this wonderful hobby, the 866 Integrated is fantastic. 

I wrote at the start of this review that an amp must be fantastic or else I’d hear its flaws through the SR1a headphones. The Boulder 866 delivers the goods flawlessly at all volume levels. I played everything from test tracks (not really fun, but necessary for evaluation) to tracks that grip me emotionally, and the 866 handle them all with ease. Reproducing incredibly wide dynamic range on bombastic symphonic pieces and the very fine details in Jewel Kilcher’s voice that bring out the emotion of an 18 year old busker from Homer, Alaska, the Boulder 866 is an all-in-one that can do it all.
