Is it a good idea to keep the output of odac at 1.0V for 1.0x or 2.5x gain on the O2?
Thanks!
Thanks!
No, optimum is to keep the ODAC at 100% volume = 2v, and then adjust gain and volume on the O2 accordingly.
As i said previously, for low impedance cans like 32ohm Grados 1x gain is fine, for 300ohm cans like HD650's 2.5x is about right. I dont see any reason to use any higher gain unless your source is low power and you need to make up for it.
I thought I didn't need 6.5x but classical music, especially slow movements of piano concertos are really quiet.

What about congestion, bloat and sibilance you reported before?
I'm not sure why but this is less of a problem when the volume is between the 10-2 o clock position than when it is below the 9 o clock position on 6.5x gain. Another observation is this bloating issue is more prevalent on pop, rock, commercial music. I don't hear the bloat too much if at all on classical recordings. Maybe the soundstage? Recording space? Mix? I don't know. I'm not an engineer so I don't know the physics or math. Just my observation.
Volume @ 10-2 o'clock at 6.5x... with an ODAC...
8-O
What cans are you using? I guess the only thing I'd notice in that circumstances with any of my phones would be the popping sensation when my eardrums split...

Classical music. Slow movement of a piano concerto. 2nd movement of Ravel piano concerto in G with Thibaudet is really really quiet.
Listening to it atm... spotify only unfortunately but still nice. ODAC at 100%, O2 on 2.5x. Highest I can bear with my K240 Sextett, which is not really efficient either although no comparision to an HE-6, is around 12 o'clock (and actually too loud for an adagio and way too loud for my ears around 6:30).
And now I was in for a painful surprise when spotify gave me a loudness war commercial - luckily I had already turned it down a bit to 10 o'clock but it still hurt...
So the question stands - what cans need 6.5x and up 2 o'clock even with Ravel's piano concert in G - 2. adagio assai with Thibaudet

I have an O2/ODAC combo and back when I bought it I had no idea what the gain setting was so I got one with the default 2.5x and 6.5x gain. I'm using low impedance headphones (Grados). Am I ruining the sound quality by using higher gain settings?No, optimum is to keep the ODAC at 100% volume = 2v, and then adjust gain and volume on the O2 accordingly.
