At least start with the 2i. It has a serviceable DAC aboard that you can play it through until you can upgrade. They are $549 plus tax. You can put whatever files you have on a USB flash drive or SSD and play 'em on it. You will find the sound and control via their app on your phone to be far superior to PC sound. Down the road you can shop for amp/speaker synergy.
Many preamps (and integrateds) now have HT (home theater) pass through so you can keep the avr for surround video.
Good luck.
