Btw, right now I'm using them with an Onkyo receiver, movies sound AMAZING with these! Also, wondering if it would be worth it to get a DAC/AMP or just keep using the Onkyo TX-SR706 with an optical cable.
I've already been through the same issue. If you are already watching movies on them, through your receiver, and you love the sound, save your money. Movies can have a very high dynamic range, and if your current setup is loud enough, it should be more than enough for music listening also. Also, the receiver is going to use higher quality DACs than a lot of headphone amp/DAC combos, which are somewhat more limited.
In my case, I went with an O2 amp because my major listening is with a computer. The sound quality is excellent, but the dedicated headphone amp was too weak for all listening conditions (anything with high dynamic range). The O2 is the only amp around the $200 dollar price point which I could find that put out enough power to drive just about anything.
If you are really wanting a DAC/Amp combo, I would spring for the ODAC ($285), with all less expensive options I've checked out a distant second. If it had to be cheaper, it would probably be something from Fiio, but in our case, their tendency for high output impedance is not ideal. Just remember that the ODAC, like most DAC/AMP combos, expects to connect from a USB or 3.5mm source.
