I had tried few low cost dac they all give an experience of timbre which is artificial... No matter the variation between chips...They all sound digital to a level or another ... And i used with them linear power supply, buffer +filters, mechanical control of speakers, electrical one and acoustical controls and good cables...
I use now my old battery dac SPS TDA 1543 to whom i came back after repair and the timbre is good and all spatial attribute of sounds ...
Timbre perception is the first and last thing that matter then all spatial attributes of sound must be there: immersive relation between sound source width ASW and listener envelopment or LEV.
I am afraid now to buy any dac under 500 bucks anyway my system value is 1000 bucks and i am totally satisfied by the S.Q. from my speakers and from my headphone...but i dont want to pay 1000 bucks for a dac in a 1000 bucks system.. i am happy to have repaired my battery SPS NOS French dac..
Most people dont even realize that the timbre is artificial using all these new dac i bought after listening very experimented reviewers... Are they honest? are they much experienced in acoustics ? I doubt it they play with gear more than with acoustics and they sell their products thats all ...
With a good system/room, everything sound relatively good even bad recording are listenable, and when the recordings are good it is impossible to stop listening music... I go on two days with Vivaldi "I Musici" box unable to stop... it is called immersive soundfield ...
Not bad for a 1000 bucks system but impossible to do without a good dac... Low cost "good" dac are rarest than " Pope shit" on street it seems as my grandmother said...
