Sure, the power supply has a bearing; without it the CD player does not
work . But you are not going to find sonic differences between $5K and
$500 or less players due to power supply; all the mass manufacturer's CD
players I have read reviews on have no trouble keeping line spurs out of
the signal.
On the other hand, maybe there is something in what you said. There may
be boutique players with really poor supply regulations. The high-end
designers are fully capable of screwing up a power supply design!
Oh, and how did you figure out that the power supply in a CD player
affects how it presents "upper bass and midrange"? I would have guessed
that the results of a poor supply would have been hum and increased
jitter. Or worse high frequency response.
