Since these measurements become somehow a standard (or pretty common), I would be more than happy if HB could publish "official" measurements of their boards, which could be a good help for customer to select the right product. Also to document the value add for the higher priced products. The test reports of audiosciencereview are also pretty nice ... e.g. https://www.audiosciencereview.com/forum/index.php?threads/review-and-measurements-of-hifiberry-dac-pro.8555/
