It's the Sony XA5400ES the best CDP under 4k

The best always depends on what sound signature you fancy. Sony has a certain house sound that appeals to some and repels others. I'm of the latter, so I'd have to say no to your question.

Listener111, I'd suggest not judging the sound until you have at least 200 hours on the unit.

BTW, did your Jolida run the stock tubes and power cord or were they upgraded? The reason I ask is that the stock tubes are terrible and the PC isn't much better. Changing them can net major improvements.

Thanks Merganser, Joild is modified ny parts connection and I have changed the tube not exactly sure what so I have in there now (RCA 5751) as I tried number of then and settled on current one for last 3-4 years.

Agree with your comment on the power cord, the improvement was huge when I changed the PC from stock to signal, never experienced that kind of improvement after chaning anythig else (Jolida 1301 ->> odyssey stratos --> Odyseey Stratos extreme)

Is it the best in its price range , no . Is it very good , yes .

Not sure whether you are talking about power cord or CD player .. the reason I am asking as if its PC then I would like to know what's the best in its price range as I am thinking of changing Zu Birth on my power amp and pre to something different.

I agree with Merganser.
