Reviews

 Adam LaBarge - The Audio Beatnik

"...when I used the PecanPi amplified by the Burson Soloist, I was able to experience some of the best and most solid sound that I’ve heard..."

and

"I continue to be very impressed by Orchard Audio’s products, and Leo has done an outstanding job with the new PecanPi music streamer."


Frans Keylard - audiophilestyle.com

"The bass is huge and the imaging is precise . Way better than I thought possible.  I even forgot about wanting to add a sub-woofer."

and

"At louder volumes (90-100 dB) the DAC exhibited its prodigious talents in a way that impressed the hell out of  me."


Paul Rigby - The Audiophile Man

 “The PecanPi sits within an attractive price point and at that price it offers plenty: impressive sonic abilities being top of the list. Specifically, an attractive blend of dynamic force, rich imagery and layered detail.”
