Based on what I found the output impedance is 130 ohm, this will have no issue driving 5k.

The PecanPi has 100ohm output impedance.

Hi,
where in your topic can I find prices for the preamp and amp. ?
I like the idea of a very small unit(s).
Also, where can I find pictures, including under the hood
if no military secret.
Thanks.

All the prices, specs and pictures on the website:
www.orchardaudio.com

There is no preamp.

There is a streamer and a monoblock amp.
PecanPi Streamer -- 499
BOSC monoblock -- 1499 per pair

BOSC will be available at up to 33% off through Kickstarter which will start in early september.

The Streamer currently has a 15% off promotion, you get 15% refunded after you write a review.

I just had the good fortune to spend the last two weeks with Leo's BOSC amps and posted my take on them here:

In my opinion, these amps are something special and worth a listen!

BOSC quality...

Every BOSC amp is hand-assembled and tested in the USA, by yours truly.

The circuit board (PCB) uses a high-quality dielectric, has a gold finish (ENIG), and is assembled in Eatontown, NJ.

The components all come from high-end semiconductor manufacturers: Texas Instruments; Analog Devices; Murata; Panasonic; and NXP; to name a few.

The output filter inductors use oxygen-free copper (OFC) and are specifically made for Class-D amplifiers.

Even though Orchard Audio is new to the market, I have multiple patents and over a decade of experience in designing audio electronics.

I believe that you will be very happy with both the sound and quality of BOSC amplifiers.

Contact me with any questions!
