cd players with volume control

are there any a serious cd players out there with a volume knob that i can connect directly to an amp?
Not knobs, but analog volume control ... Resolution Audio CD-50 and 55, Theta Miles, Proceed CDP and Levinson 39 (sort of analog) to name a few more.
a conspicuous model by its absence thus far: the accuphase 75v. digital volume control that will not degrade the sonics by rolling off high and/or low end at varying output levels, as will the "analogue" pots. you can't appreciate the best unless you audition this one-box player. trust me; i'm a lawyer. ;~) -kelly
