RPi and SD Card are not included with this product.

Boss is/was the most successful Dac made for RPI. The combination of great sound and great value proved very successful.

After 3 years we felt the need to upgrade. The only questions were... how can we make Boss2 sound even better? how can we provide better value?

For sound quality we decided to use the new Cirrus Logic DAC CS43198 as a master (another first from the ALLO team). Unlike pcm5122, it has excellent THD (-120 vs – 83). Unlike Ess, the sound is “darker” (not bright, low out of band noise).

We are using over 30LDOs (as usual), two super caps and countless filters. We also upgraded the power input filtering with common mode chokes.

We recommend Nirvana (with earthed switch on) for best sound quality (measurements) but even a cheap PSU will degrade the THD by 1 to 2db.

Boss2 is a meaningful upgrade over Boss in sound quality (measurements, THD / Jtest) and a much better "bang for your buck".

While the WIFI of RPI4 is better than previous models, it is still not great. We highly recommend adding our WIFI dongles (or use your own). In our tests, RPI4 + Boss2 with acrylic can reliably play hi resolution files with a standard WIFI access point no more than 9 to 10m away. Boss2 and RPI4 with ALU case plays reliably at around 5m or less. Using WIFI dongles will increase the range substantially (we are able to reach even 20m through one wall).

THD+N -114
