Wadia S7i vs Esoteric K-01/K-03 vs MSB


As I want to upgrade from Sony XA5400ES has someone compared the following:

-Wadia S7i
-Esoteric K-01 or K-03
-MSB with Platinum Dac IV plus, Signature Platinum Power Base, Upsampler 384 kHz and Platinum dac IV transport or any other MSB device.

I got already a great deal on a used Wadia S7i, which however is discontinued now.
I have no possibilities to compare any of these and apparently there is no specific information available on the net.

Thanks for making any efforts.

@Gpgr4blu,
Do you have any comments on the general sq of Esoteric vs MSB.
I already ruled out the Wadia for the reasons you mentioned.
Thanks for posting.
Hi Gpgr4blu,
Thanks!
Said by other members that the best MSB stack is way ahead of the Esoteric and even surpas the P02/D-02 combo.
So at this moment I would stick with MSB with also having the advantages as mentioned before.
@ Sequence56, Have you considered Luxman?, I have heard great things about their sound, compaired to what is under discussion here!, I have seen some audiogoners pick the luxman over the best available here!, what is everyones opinion here on the Luxman versus whats mentioned on this thread?, cheers!
Fellas,I also feel we should add Accuphase to the mix here as well!, then let the fun begin on our opinions!cheers!
