This may just be a dumb question, and that’s alright as I’m genuinely curious. In the case of the low gain setting on the “medium gain” amp, wouldn’t an output of 1.0x be equal to the input? Anything times one is equal to itself, right? Now, that could be the case as in no increased levels of volume, but the signal will be stronger and more stable resulting in less noise. So, how exactly does it work when dealing with a factor of 1.0x?
On that note, I would be using the desktop amp almost exclusively for IEMs, and all of my current headphones (as well as IEMs) are under 300Ω, but I do plan on getting some high impedance headphones down the road. It’ll probably be a while away before I do go in that direction. Should I opt for the “medium gain” amp now? Keeping in mind my question above, I do like loudness (but when it’s also clean). Will the high gain setting give me a good sense of loudness for most IEMs ($200-ish average)?
