Default Capacitor upgrade for Cayin CDT-15A

Hi everyone,
I'm planning to upgrade my Cayin CDT-15A Player by replacing its output capacitors. The original capacitors are two RealCaps (a 3.3uF parallels with a 0.1uF). So I'm considering between Mundorf Supreme and Obbligato Gold Premium (both pricing around $20/each of 3.3uF, the Mundorf cost a little more). I also want to know if the paralleled 0.1uF cap can be removed when I replace the 3.3uF cap.
All advices and recommendations are welcome. Thanks!

A parallel capacitor is not a good idea. It will give an oscillation circuit and sound will become worse most of the time.

This is absolute nonsense. What you describe is utterly impossible in audio circuitry, and all but maybe microwave rf circuits. I don't know where you got this idea, but it is rubbish.

As to the OP's question, please don't confuse "RealCap" with "RelCap". I was rather amused & disgusted when I first worked on a Cayin piece and saw those "RealCap" caps, so blatantly trying to appear to be RelCap Multicaps. If you replace with actual RelCap Audiocap Theta or Alpha propylenes, finished off with a 0.022-0.1uf RelCap RT styrenes, I don't think you can do much better.

Thank you all,
- From what I heard, the parallel capacitor have at least 2 reasons: to reduce the total resistance and inductance of the caps; to improve the high frequency at which the small capacitance cap works better than the big one. Anyway, with the high grade caps, I think it's not necessary to use a parallel cap at all
- gentlevoice: Thank you for useful link. From what I read there "Making a capacitor using about 90% Clarity Cap SA and about 10% Mundorf Supreme works very well, this tends to open up the top end just nicely without altering anything else", I will consider to have a 3.3uF Clarity Cap SA parallels with a 0.1uF Mundorf Supreme (But I still don't know if this is a good idea?). Anyway, if possible to throw away the parallel cap and use only one cap, I think a 3.3uF Mundorf Supreme is a right choice for me.
