Is the Paradisea or any other CDP or combination of both the best in the world..not a chance. That product doesn't exist.
I've heard the original Paradisea and the USB+Paradisea with at least 8 different mixtures of transports. The transport in deed makes a major difference in the sound from these units. The best sound I've heard from these were all PC based transports. Will it beat a 10 grand unit..who knows. That's in the ear of the beholder. Will it embarrass some $2600 Cd players ?...sure nuff. I have Agon feedback and paypal transactions to show it without any doubt put a $2600 well regarded player in the ground. For me that's terrific coming from a $600 Dac...actually I think that's fantastic! Am I happy with that..sure nuff!
I've spent more and gotten much less...anything that gives me the opposite of that...is a winner in my book.

As much as I liked the original Paradisea.. which was no slouch..the newest version is better.
I've considered even buying a Lector(used of course, I want to get my money back out of it when I sell it back off) just too listen for myself in my own system. The gain differences should also be taken into account. 1 extra volt of output makes a helluva difference in what one perceives as better.
This hobby is so subjective..there's really no right or wrong. As long as it makes you listen to music more that is the only thing that really matters.
Good listening
