Yes, thats how i mean it. Never realized that myself. My older DAC based on BB PCM63k had for sure more audible clipping on overcompressed recordings. I often heard that when my tweeters puked. I noticed it became less when i switched to the Transporter. Since i used its build in volume since day 1 i may have solved that problem once and for all even without knowing about it :) Benchmark introduced some feature in its DAC2 that " includes 3.5 dB of headroom above 0 dBFS" whatever that means. Maybe some DACs these days have this build in or they use some pre-defined volume drop.
