I have a pair of DT880s 600 ohm headphones. My DAC/Amp is the Apogee Duet for the Mac and iPad, which is the most recent version. I found the headphone out to have the higher frequencies boosted a bit. So I tried the line outs. No such problem anymore. I do not hear any distortion, and this sounds very similar to the headphones out in sound quality. My dampening ratio is about 7:1, but this works quite well. Go figure. The way I see it, the headphones out is never as good as the line outs of an amp. Research on the performance parameters such as FR of both the headphones out, and lines out, confirm this. My high impedance headphones seem to be making this work.
I heard somewhere that the high impedance headphones are less sensitive to damping ratios. Is this true? On another matter, as to a problem that rarely happens, playing high res files from Qobuz, there can be a couple moments of static. When I replay that same passage of music, there is no static. What can be causing this? I do not think it is my DT880s. Isn't there some error correction or handling in the protocol that sends the audio over the Net?
I usually like headphones with boosted trreble, but these seem to have it in a region where it did at times seem a bit harsh. My Audio Technica ATH-AD700s have as much if not more treble (made more apparent by even less bass), but seem less harsh.
I keep going between these pads for a few months then back to the originals and they make them sound so different. Much more punchy bass and because of how much treble these have, it doesn't take away enough to make them lacking in this area. They make the midrange warmer and the overall sound more balanced. If I want a brighter and slightly more spacious sound, I go back to the original pads, which are softer and more comfortable. But then find I often want to boost the bass, which on my A3 adds distortion when it gets close to maximum volume. This is why I use the other pads more. It adds bass without having to add it at the source.
