Okay, I just had another system change change. I have switched out the Yamaha A-550 integrated amp for a separates combo, an NAD C162 preamp and a Rotel RB-951 amp. So I increased from a 40w/ch integrated amp to a 50w/ch amplifier. I must say, the Rotel amp and the NAD preamp make the Monitor Audio Bronze BX2's shine! I get more impressed by these little gems with each system change and addition.
Of particular note, I have a Schiit Audio Modi DAC to bypass the LG DVD player's audio section... with the Yamaha A-550 there was a subtle but audible improvement in delicate music, jazz, and acoustic instrumental music but not so much with in-your-face rock music. There is a bigger audible improvement in the sound when using the Schiit Modi DAC compared to the LG DVD's RCA output, with the NAD/ Rotel separates than was audible with the Yamaha A-550 integrated amp. All three Yamaha's (CR-420--> R-700--> A-550) sounded good. Each change improved the overall sound a bit. Adding the Schiit Modi improved the system a bit more, but this last change really panned out. I think I might have a new crush... Rotel & Schiit Audio to go along with my Monitor Audio and Thiel crush.
What to do next? I am considering a slightly higher line DAC, a Schiit Audio Bitfrost with uber analog. Any thoughts?
