Do CD Transports benefit much from upgraded power cords?

Yes, they do....generally speaking, of course.

I have used many CD players of varying quality over the years.

IN GENERAL, the nicer the CD player, the better the unit responds to a nicer cord.

If you are using a cheapie CD player (say....under $1k), you probably won’t hear a difference.

When you start talking about $2K+ players with quality power supply(-ies), then yes, you can hear a difference. I don’t think you need to go overboard with the quality of the cord, but a couple-of-hundred dollar cord on a good CD player will be noticeable.

(It’s easily demonstrable with my Esoteric, Yamaha, Classe, modified Denon tube CD player, etc...)

Everything makes a difference on audiophile equipment, and CD players are no different.

P.S. Nice setup. Love the speakers!

Only a complete moron would equate a $4k CD transport/player with a hair dryer.

Ignore the troll.

It’s unfortunate, but the guy has no real equipment, and as such, feels the need to shout on every cable post that nothing matters. I mean, if you have no point of reference, I guess it doesn't. 

Same guy was "schooling" me on how his $15 DVD player sounds just as good as my $6K Esoteric. Uh-huh. Sure it does.

Some people just aren’t worth arguing with. He’s not here to learn anything. Ignore him.

Ahhh, and here come the angry emails from our resident troll.....lovely. Lol.
