I think you are missing the point. standards exist for a reason.Well, so. It's not really common to have this amplifier either. Cables are very cheap, on amazon one can easily find premiumcord cables cheaply. I now have 3 different sets of balanced cables.
every other hi-fi amp uses XLR and/or RCA.
but Topping uses much less common things like 1/4 jacks, see other amps they produce.
at least in this case it's compatible with XLR, better than nothing.
