 Wayne - Littleton, CO

"This is a very well engineered and built DAC. I again suggest folks sign up for the tour and listen yourself." and "I spent a good week listening to it and came away extremely impressed with what Leo has done with this DAC hat."

Alan - Harrisburg, OR

"I have had the Apple Pie for a while and I must say I am really impressed." and "Any way this is a dammed fine budget setup that punches way above it's weight."

Sharschchandra - Austin, TX

"The build quality is top notch and I really like the layout." and "The unit sound great out of box, very organic, almost neutral and full bodied (compared to ES9038PRO based DACs). The vocals were amazing especially on the JBL 4312B monitors."

Jerry - Camarillo, CA

"This is one sweet little Dac, Leo. I actually left work early today just to spend more time getting to listen." and "You have one helluva nice piece here; I appreciate the gracious demo."

Henry - Great Britain

"What I found was a very good sounding device with good accurate tight bass, excellent mids and good calm non splashy highs. Audible cues were there and straight away I knew this was the best I had ever heard through a Raspberry Pi."
