PecanPi -- Raspberry Pi DAC and Streamer

(thomas clark) #191


Ive recieved my pecan pie streamer and I am pleased.

I had been using an Allo Boss.

Pecan Pie had better defined bass and a better punch.The higher tones of the bass were tighter.

Instruments were separated much better which allowed for me to hear subtle sounds in the music id not heard on previous listens.

Has a brighter over all sound vs The Allo.

Not easy for me to describe sound with words but i like how it sounds than my Allo Boss so thx for all your work

Read the latest PecanPi Streamer customer review:

“I needed to find a streamer to play my music from PC to my aeging, but still excellent hifi system. I read a review of the PecanPi and emailed Leo. He responded almost instantly, even though I’m in Australia, and I ordered my unit. It arrived this morning, and to say I’m blown away is an understatement…”

An awesome review for the BOSC amp:

“Class-D amplifiers generally trigger reactions and opinions of a generic, mass-market sound. And I’ll admit, I tend to not be too curious about anything based around that amplification method. But Leonid (Leo) Ayzenshtat’s Class-D amplifiers continually force me to think differently. They prove that it isn’t about the type of thing, but rather about how skillfully a thing is made.”

“I wanted to stop my heart so I could hear the music better. I was being sucked in, pushed out, and unable to focus on anything else but the music. There were all the little bird-like chimes, dancing between clicks and pings and bongs of xylophone harmonics with dry reed raspy sounds zooming in and out, floating on top of deep rolling strings and organ-like bass. I didn’t want to miss a moment of it.”

It takes AC power input? Worldwide voltages? Can’t see any clear photos showing power input.

The amp takes DC, it comes with a universal 250W AC/DC power supply.


Thanks. What is the model of AC/DC power adapter.

And the DC plug size?

Leo, fascinating review. He’s right - my experience with several Class D amps also elicits an expectation of a certain type of sound quality and based on this review, it certainly sounds like you’ve broken that mold - in a very positive way! I’m quite eager to hear your BOSC amps to better understand just what this reviewer was hearing. Exciting stuff!
