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.
