Save yourself a lot of money and consider a Parasound Zpre3, with HT pass-thru (easy mating with your Onkyo if going to use for HT), tone controls, remote, etc. No phono stage or DAC, so you pay for neither of those. A great value and very good sound IMO.
You will be pleasantly surprised how much better 2 channel sounds getting your AVR out of the chain for music.
