All commercial audio equipment is built with compromises and trade-offs.
A common trade-off is price versus quality. Another one is parts count.
I can easily see a case where Onkyo would have like to have used certain
higher quality parts, but ended up using something less to hit some
marketing price point. One never knows what kind of improvement could
be made by changing out low quality capacitors and putting in low noise
op-amps.

So, you change the PSU and it still sounds like an Onkyo instead of being
transformed into a Krell or whatever. What do you modify next, or do you
just say stuff it and buy something better, maybe 'used', in the first
place ?
