That said, you also might look at the TCC TC-754 since you are running powered speakers. It is a phono preamp (TC-750 circuit), audio switcher and volume control all in one

Since they are 4-6Ω it is going to be a touchy thing getting something with those nominal loads to not overload most modern receivers. If you DON'T need video switching you can get away with a pre-amp+amp and do this a lot better with something like TCC preamp and a Behringer A500
I have the TCC TC-754 and it sounds wonderful!

They also make a smaller version of this is you do not need the additional aux inputs.
I've got that same Onkyo unit plugged into this: https://www.massdrop.com/buy/aune-x1-pro-dac and I love it! The X1 is a pretty decent DAC, and I use it like a pre-amp for my 282. It's nice to have the volume knob accessible (I keep it beside my bed) and the larger headphone output.
Into the line-in of the X1 I plugged in one of these: http://www.amazon.com/TC-754-BLACK-Phono-Preamplifier-Switchable/dp/B000ZZINTK and have a record player and bluetooth adapter plugged in. I leave the audio knob at max for the tc-754 and just control it through the X1.
All in all, I think it's a great setup made from some fairly budget components to make a highly functional system.
