Best older universal for CD playback??

I am wondering if anyone has compared the universal players below for CD playback sound and what were your observations. I am trying to stick with one machine verses one for DVD and one for CD but that can be tough I cannot afford the newer units and to me many are hyper detailed and not what I am looking for. I have heard the DVD 7001 and DVD 3800 and thought the Denon was warmer. Probably the ALPHA processing. I had that on my Denon 1650AR I had for 9 years and it did make it more musical and analog. Thanks
