Great set-up! I'm a 2-channel man myself, have been sense the mid-1970's. I guess that's what happens when you grow-up with it. I use the PS Audio P-10 regenerator and I can't say enough good things about it. You absolutely do not have to use a computer. I'm like yourself, at this time I don't use a PC in my system. Maybe down the road when high res. digital is the norm, but for me at this time there just isn't enough music available that I like in high res. As far as the P-10 it's really overkill for me. I could have gotten away with the P-3, but I came-across a good deal on a pre-owned. When it comes to firmware updates just like my PS Audio transport and DSD I use the SD card mounted in the rear to transfer updates. Once again, the P-10 does it's job wonderfully without the PC.
Happy listening!
