Going through your options my recommendations would only cost $200 more than your Best Buy options and result in a much better system IMHO. Plus, when everything I recommended can be delivered to your door for little/no cost there’s no reason you need to be wedded to Best Buy to purchase everything. So, for the turntable here’s the comparable BB turntable, but for only $50 more my recommendation gives you both a better tonearm and cartridge, which is a lot for 50 bucks.

As for the AVR, I’d stick with Yamaha because I’ve compared it directly to Denon and Yammy just sounds better (I worked for Magnolia so had access to do extensive comparisons). The RX-V4A would be my choice of your options, but at BB it’s only $50 cheaper than my recommendation that offers more power and comes from the upscale Aventage line that uses higher quality parts and design. Also, it offers front L/R preamp outs if you ever want to significantly improve performance by adding a better amp or, even better, an integrated stereo amp.
For the speakers, you’re just getting much more speaker for only $100 more with the LSA speakers. They weigh 37% more and go much deeper in bass than the Q350.
So, all things considered I’d stick with my original recommendations given all the above advantages for not much more $$$. Just my $0.02 FWIW.
