So, right now I'm using my Pioneer Elite VSX-52TX as a pre-amp. Taking in the digital from either my PC or ChromeCast Audio. Going pre-out to a Yamaha RX-777 I picked up for $50 on Craigslist. I pulled the couplers on the Yamaha from between the pre-outs to the main-ins, and ran the pre-outs from the Pio to the main-ins on the Yam. So I bypassed all the circuitry in the Yam & using the Pio to control the volume. I also turned off all the speaker outputs on the Pio to reduce heat & other electrical interference as much as possible & running in direct mode on it (not sure if it makes a diff when running through the pre-outs on it). It sounds great. I still want to do some A/B comparisons.
I also picked up a Denon 4311 just because it was dirt cheap around me. Going to play with that also & try & compare. Not sure it will be worth trying to do some bi-amping or try-amping with any of these configurations, but I thought I might try it with the Denon since my bi-amping zone 2 speaker outputs aren't working on my Pio.
Currently looking into an Emotiva UPA-200 someone is selling locally here for $175. Not sure if it's worth it or not yet.
Got any thoughts or opinions on any of that?
Thanks.
