You are perfectly right and i am conscious of the limitation of the SPS because my room is acoustically under my control and not only treated...
The SPS lack in the high range, it is less resolving thats all compared to many very costly dac ...
My imaging, soundstage and LEV/ASW ratio are over the roof and under my control and this dac dont impede my acoustic at all..
But it is not a microscope...
Then even if the Audio Note will be better resolving i dont need it for cost reason and anyway if i bought it my old Sansui so good it is, should be replaced and even my speakers would be not so much efficient now at the level of this more resolving source...
i dont miss this potential improvement at all, because there is a minimal objective treshold od acoustic satisfaction for what we call an audiophile experience acoustically and i enjoy this minimal experience so much now anyway , that any upgrade even for the better have no appeal....
But you are probably wrong about my Sansui AU 7700 sorry ... I dont bought it by chance... The Grundig V1700 will not beat it ....Sorry....😊 I even own a Sansui of the alpha series supposedly better ....If i wanted a real upgrade from these Sansui amplifiers which are top FLEXIBLE Sansui with separated amd-preamp section, with tone controls rivallling others, i must buy a ZOTL Berning tube amplifier and yes i will beat the two amplifier i own at relatively low cost... But with your suggested new dac and this ZOTL amplifier i will want to buy very costly speakers now, and to beat the Mission Cyrus 781 bass and beautiful sound with more resolving power guess how much money i will need to pay?
A big amount.... 😊
I am not in an upgrade mood anymore after my ecoustic experiments in my dedicated audio room...I dont need to....I could not even use my 8 headphones now because they dont beat my system/room... Then ?
No problem Mahgister - I too remain open minded with regards some low cost items sounding very good in the right environment (hence why I purchased the SPS DAC3 but now finding that inadequate once you have listened to something like the AN 0.1x).
