Hey thanks for taking the time to answer my questions... just a few more if you dont mind:
Talked to schiit and they seem to think stacking modi on A2 for long periods of time is no big deal. Just hope they say that if/when i have a warranty problem haha.
I understand what youre saying but is there any drawback to run modi at 24 bit while playing 16 bit FLACs and leaving 100% comp volume and using A2 volume control? or is there just a drawback when you run modi at 16 while playing 16 bit FLACs and you don't have comp volume at 100%?
In the same vain, how about when im using an aux cable in my car with an iphone? I guess i would want to keep my iphone at 100% and using the stereo to control how much output i want?
So as i mentioned i'm thinking about getting the Adam Audio F5s which are powered monitors. I'm going from usb to modi to asgard 2 to F5s. I guess Asgard 2 is helping to preamp the signal before it picks up noise from the modi to the F5s? Is the quality going to be that much better than if i go from modi straight to the F5s? I'm guessing the Asgard 2 can drive passive speakers as well?
Modi in 24 bit with 16 bit music and comp at 100% should be the best quality (16 bit music to 24 bit dac is bit perfect, just with an extra 8 bits of padding). Only actual potential 'drawback' is if it's 16 bit Modi and 16 bit music with comp < 100% (and even that's theoretical, since most people probably wouldn't hear the difference during normal listening). Still, the first scenario would be the way to go unless there's some reason to have your comp at < 100%.
With your car and iPhone...since the iPhone is amping it first then it might be better to turn it up all the way and might be better a little below full volume, but that depends on if the iPhone clips when turned up all the way so I can't really give you a guaranteed accurate answer...for that I'd just try it both ways to see what sounds better to you.
If you're only going to be using the powered monitors (and don't mind using their volume control) then you can go Modi directly to the F5s. Having the A2 in the chain just means you have a separate volume control if that's more convenient. The A2 can't drive passive speakers to any useful degree, the preamp functionality is just to run into powered monitors or a proper speaker amp.
