IBut the specs you were showing for those products will not help you gauge what the product will sound like. What DAC chips are being used? Buffers? Output stages? Caps? Power supplies? Those are the things we need to know to better get an idea of its sonic signature, assuming the listener has already heard those electronics in other pieces of gear.
As an example some chaps at a Spanish HiFi club tested an Oracle CD player against a Pioneer DVD player, nobody could tell them apart, it is highly likely that the Oracle had boutique parts and the Pioneer a slew of off the shelf parts - though this is a bit speculative on my part (sic). If the two were indistinguishable it may be that the Oracle despite cost and parts was a poor design and the Pioneer optimised its cheap parts with a more appropriate design , or perhaps they were both crap but one was just massively overpriced . If they were both equally good but the pioneer just happened to be 1/60th of the cost then that gives pause...Goldmund for instance rebadge Pioneer DVD players and mark up the price to $12,000.
As for the PS1 SCPH-1001. I only had one for a few weeks but it compared very favourably against my other budget CD players i..e Marantz and Onkyo, beyond that I would not speculate.
