Burl B2 Bomber DAC THD+N vs Input (dbFS)-8dBu output setting or 12dBu max output (GRN/RED)-18dBu output setting or 22dBu max output (BLU/ORA) The lower output at the -8db setting results in overall higher THD+N (it's the noise floor) than the -18dBu setting, but the distortion harmonics are overall lower and don't climb up as high., The Solaris soundstage is deep, placed behind the wall. I don't think this translated well with headphones because soundstages that are too far deep don't exhibit instrument depth localization in headstage. The Burl B2 Bomber's stage is moderately deep, but not so deep that instrument depth is lost with headphones., The overall tonality of the B2 Bomber is slightly warm. By slightly , I mean quite a bit less warm than something like the Bifrost 2. There is a smidgen of outward warmth (give the DAC's output stage a few minutes to warm up) in terms of upper bass to lower mids., Hello, I’m still enjoying my burl b2 bomber dac but I’ve been considering going portable, so she might be looking for a new home. Gungrave , Jul 7, 2022 #108, The Burl B2 is a very pro oriented DAC, and thus doesn't have any single-ended RCA phono outputs. It only has balanced outputs. The balanced outputs are very hot (pro voltage levels), however, there is a knob that allows you to set the maximum output level at 5 detents ranging only 10db., I have a Burl B2 Bomber DAC and have been listening to it since December 2018 using Dante with the BOPA1 and have upgraded to the BOPA8 by calling Burl and ordering a pair. I'll say your observation is pretty close to mine. The BOPA8 needed a little break in time but it does have more depth and is sharper..
