Hello, I just joined, primarily for the audiophile products. Looking at purchasing the NHT C3 speakers for our new living room. Space is about 15 feet wide by 33 long and they will fire long ways. Space is just for general listening, music room with all equipment is downstairs, so hoping they will fill it with sound nicely. Cheers.

I'd like to pair this amp with my ODAC (also from NwAvGuy, I'm a huge supporter of his work, the DAC is awesome beyond telling for such a low price). However I'm hesitating on which O2 version is the best for my use case.
- I will use the Sennheiser HD6XX from Massdrop. I hear they need ~2Vrms on NwAvGuy's blog.
- I'm using the DAC mostly at home (occasionnally in my car, powered by a Nexus 6P USB-C output), so I bought this DAC outfitted with RCA outputs, as it's more often than not driving a classic receiver+loudspeakers. (it's revA of this one: http://www.headnhifi.com/dac/odac-xl-version) Apparently, this DAC consistently outputs ~2Vrms from what I read on NwAvGuy's blog.
I'm thinking the O2 Desktop with medium gain (1X | 3.3X) is the way to go for me.
How I plan to use it: using very short RCA cables, I should be able to send ~2Vrms from the ODAC to the O2 (regardless of the digital source, the analog output of the ODAC should always output ~2Vrms, right? Phone or desktop PC should not matter?) and use the 1X gain setting to drive the HD6XX. Am I correct?
If Desktop O2 with medium gain is fine, then I'll get it here, otherwise I'll probably buy it from Head'n'HiFi. Unless there's a better amp to put in-between my ODAC and the HD6XX. Thanks anyone who can help me decide what to get! :-)
