Tubed CD Player w/ solid state amp?

The more I research different CD players in the $2000-3000
range, the more confused I seem to get!(It's a big purchase, and perhaps a tough spousal sell) Over the last few weeks, I've asked a few questions relating to my search, and have gotten some good advise. Complicating matters is a lack of high-end dealers in my SE PA neck of the woods.

Some of the players that continue to draw my attention are some of the usual candidates discussed here:

GamuT cd1R
Ayre
Simaudio Nova
Metronome
Audio Aero Prima

I'm looking for a match to my Plinius amp and Totem Forests.
Some of the units I've looked into are tubed. Any advantage or disadvantage to a player with tubes,especially as it may relate to my amp etc? (I listen to a wide variety of musical styles.)

On a separate note, is a CD player's power cord as important as it appears to be on AGon?
