Dude!
You and I have some equipment in common! I can make some recommendations and my reasons behind each one.
So, you want warm and musicial but you want some price options? New Audio Design C 541i HDCD/CD player. You can pick one up used for about $325 USD. It is a warm, full bodied, tonally balanced, and very musicial player. It is also one of the top budget CDPs on the market in my humble opinion. With the Grado RS-1s and Emmeline HR-2, the NAD C 541i HDCD/CD player will demonstrate very good synergy. You'll hear it. It will complement the Grado RS-1's signature sonics: warmth, smoothness, full bodied sound that has plenty of bass slam and well extended, airy, trebles along with a luscious, intimate, midrange. All you'll need is a pair of DiMarzio M-PATH ICs for about $90 USD and you'll have many happy hours listening to your system. I guarantee it.
NAD recently released the C 542 HDCD/CD player for about $600 USD. What's the difference? In one word, the reviews seem to indicate refinement. It takes upon the sterling sound of its predecessor and refines it. Bass is better extended, fleshed out, and quicker / tighter. Midrange is about the same: luscious. Treble region is better articulated and extended with less treble bite.
If you want to get into high resolution, then I'd recommend picking up a refurbished Denon DVD 2900 "universal" player. It's not like the NAD house sound. It's much more detailed, neutral, and transparant. A terrfic number of reviews are available online. Go to
