This is a reply to an old post. An audio friend has added the PS1 added to his K1X se and he has indicated that the sound is a big step up from his K-01XD and in fact compares favorably to super expensive Wadax setup. Just his two cents.
Esoteric Grandioso K1x owners - have you added the PS1 power supply to your player ?
Hello Audiogoners - I hope all is well and just wondering if any owners of the Grandioso have added the Esoteric PS1 separate power supply to their players and was it worth it monetarily as well as sonically. Thank you in advance.
