I don't think these kinds of tweaks are worth it either...
Love to see someone demonstrate hearing a real difference under controlled circumstances.
Trading dollars for no improvement doesn't make sense in the non-tweako world...

The point I was making when I said that a Linear Power Supply is not to be considered a tweak
was that if one, decides to replace a cheap SMPS with admittedly less efficient LPS (this is not a tweak)
A SMPS as supplied by the greater majority of manufacturer's, is to keep the costs down.
Unless it is a SMPS as designed by Benchmark.
Then we have a SMPS that is of the quality of a LPS and possibly better because it will be more efficient,
There are tweaks and false prophet's in this Audio Industry who can convince the unaware
to part with very large sums of money,for absolutely no improvement(on this I agree).
A power supply in electronics is a different story all together,
even Matrix Audio suggest that a improvement can be made by replacing the SMPS with a good LPS( Matrix i )
Implying that the SMPS is a compromise to keep costs down,the thing with Matrix though is they use
LDO's throughout their circuitry to compensate for any negative power supply issues.
I emphasize again, that if a effort is made to design a SMPS like the Benchmark Amplifier has
then this will be more efficient and quieter option / than a good LPS.
It may surprise some to know that the OPPO 205 that measured very well here,has a SMPS
and that is possibly because OPPO like Benchmark,went to the trouble to design a proper
SMPS.Make no mistake the cheap SMPS as supplied by the greater majority of electronics
manufacturer's, has now place in audio electronics and should be eliminated.
I will also say it appears the the Hypex SMPS appear's to be of correct design,eg: NCore 400 etc.
