I've looked into both the Rotel and the Marantz amps. I was advised against pairing the B&W with the Marantz due the combination producing music that is "very bright, and wearing on the ears." Granted, I tried out a Marantz Receiver (not integrated) at Magnolia with the B&W 685's and I enjoyed the result.
I have heard that Rotel is a great choice, especially as they come from the same manufacturer if I've read correctly. But I have yet to find a place to demo a unit.
One other receiver that has come to my attention is the HK 3490. I found it online for $280 making it close to half the price of most of these (and only a third of the price of others). It also has a phone pre amp and a built in DAC. Will the Outlaw, Rotel, or Marantz produce sound that is significantly superior to it? I like that fact that it is a tad easier on the wallet, and if I weren't to like it, I could upgrade down the line. The money saved would likely go toward funding a basic turntable as well, such as the Debut Carbon or Rega RP1. I know asking questions such as "is the upgrade worth it?" are highly subjective and it comes down to the individual listener's preferences, but I don't have a "trained" ear yet, and as such, I am leaning toward starting with the HK 3490 and moving up the ladder toward a Rotel, or something of that caliber, down the line.
