i was so glad to witness with my ears the true power of the sony zx500 walkman. over some time i had been listening and trying to get an edge on my custom setups but in some amount i was worrying i would never get any further ino the quality unless i did something more and more with trying efforts to save my sanity. with the flac sliders i aimed at trying to get better quality and it really worked. the hardware in the player set itself up to the conversions with more process of it being a technology in itself and where it began to take more into quality where my conversions had been adjusted. the aging process of the amplifier capacitors polymer base still isnt complete yet since i had got it in march 2021. it takes about the frame of full 20 days of listening for the aging to sort of kick in, or about that much. it was glorious to hear the flattop rounds kick in where the amplifier did its job and play the rounds horizontally without the noise and vertical "trying up" where the ageing of the capacitors were still makeing its way. i can hear more and more the flowering of flattop in my conversions grow more mature and more like the intension of the muscicians guitar work where every millisecond makes up for small tuneing into the musical notes. this  sony player really is worth having, the quality gets better and better, wow.
