Latest thoughts on this amp. I really think low gain (I did think this on the HD600) is the way to go if you aren't doing EQ or low EQ (don't need the extra gain of high gain). It seems like high gain has some advantages like a more immediate full sound. But I feel like it's very hard on a good amount of songs to get the volume right where the voices sepearte from the other instruments. High gain seems unnaturally boosted, or maybe it's just a lot harder to find the sweet spot for volume. You have to turn up low gain pretty high on this amp, but it seems much easier to hit the sweet spot where a song sounds natural.
But perhaps these thoughts apply to every amp and why people suggest always use low gain if you can for lower noise floor (general concept, not sure how much it applies to this amp).
Edit: I completely changed my mind to high gain with 660S2 headphones using HQPlayer. I now think high gain is better on this amp because you can make small adjustments perhaps easier (since a lot of the volume is at the end of the pot). In High gain, you're at a much lower volume pot level which again I think makes it easier to make small adjustments and make sure you're getting dynamic volume with an accurate sounding filter/modulator. Loving it!
