Wadia CD players direct to power amps opinions

Has anyone ever used a Wadia CD player without a pre amp? Connected directly to a power amp.

I am really more curious how it worked with a Tube amp?

Which model Wadia player did you use?
If so what is your opinion of it?
What amps did you use?
Speakers?
PC’s and interconnects?
How was the experience?
Detailed, noise, sound stage etc.

Thanks for your insight and I am looking for truly serious replies please.
