Budget CD player with volume control?

Sony XA7ES has variable outputs that enable connection to your preamp and you can control the volume via Sony's remote. Sweet sounding player, very nice and can be had about $900 or below used.

Keep in mind that the volume controls on budget CD players are generally digital. That means that when volume is lowered from max, it affects the bits and thus the resolution of the output signal. You might be better off picking up a used Creek OBH 10 or 12, a passive remote preamp often available for as little as $150.
Do a search here on Audiogon on analog vs. digital CD volume control for more information on this.

I own a Cary 303-200 with volume control and metal remote. Good build quality,it sounds great and you can pick them up used for about $1500. or so.
