CM Caps


I opened one of my amplifiers (Chinese Image 34i). It has four CM-Cap coupling caps (each has a legend: "CM cap for audio MPT 630 VDC 0.47 uF J")

Any opinions on these caps and is there any reason for upgrading them by better caps?

Thank you! It is a nice amp indeed, especially because I upgraded it with vintage tubes. Still, it is too "polite" and does not have "slam" of higher grade amplifiers. I looked inside and saw more or less neat soldering job, but there is little space inside to install bigger and higher quality caps. I will ask my technician to have a look at it in order to decide whether it would be easy to solder new caps.
Why does the company call itself Nelson Audio? Because the designer's name is Nelson Ho? How do their products compare with Cayin, Mind-Da or Yaqin amplifiers?
The Nelson Audio amplifiers are quite reliable. The 65i integrated amplifier powered with 6550 tubes is highly praised. My amplifier (34i) is definitely lower grade and I am not sure whether it is worth upgrading.
