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.

Not sure about your budget but if you don't need SACD playback, have a look at the Playback MPS-3. MPS-5 plays SACD but may stretch your budget a bit. Well worth it IMHO.
Sequence,

No disrespect but for that kind of money you owe it to yourself to listen to each player for yourself. I have a MSB DAC and I am very happy with it but the others on your list are top notch as well.
