If I have my volume at 100% in Windows the Q701 only needs to be at around 20-25% or so on the Magni (using ODAC). I'll double check this tonight, but it's VERY low.
Sometimes I just reduce the volume control in Windows, but I can't really notice any differences in sound quality.
For some reason my K601 is the only headphone I have that needs to be up around 40% or so.
On the E9 I believe the Q701 is at around 30-35%.
The Magni does have a ton of gain. I always say that i'll be shocked if anything exists that needs to be at past 75%. I know volume doesn't always mean much..
BTW using the DJ100 with the volume in windows at 100% is kind of scary! I don't think it needs to be past 10%. Totally overkill for the DJ100 which is 38 ohm.
On my Micro Amp my Q701 is always at 45% on medium gain. This is basically like low gain on most amps, but on the Micro, low is really only useful for IEMs.
Not that anyone asked! High would be at about the same level as the Magni.
I've never heard any noise or hiss with any headphone other than my DJ100. On my DJ100 (38ohm) I heard some hiss/noise, but it was due to a crappy cable with poor shielding!
I got it from Guitar Center and it's one of those generic brands. I then tried a Monoprice, RCA and metal shielded GE Ultra Pro cable and it was dead silent! This was the actual cable going to the headphone though.
Someone said the Monoprice cables don't have shielding, but I think this is impossible! Mogami has very good shielding too.
I get some weird bass distortion/crackling with my Magni when using thin cables. I don't have a clue why. It's now even occurring with my new Monoprice cables (the thinner versions). Only on one headphone though. Makes no sense.
When I switch amps it's gone.
Oh yeah, if anyone was curious..the Magni drives the 600 ohm Sextett with ease. Sounds good too.
