No plugin for foobar but standalone for sonarworks and vst trials for both:
Morphit: https://www.toneboosters.com/download.html
Sonarworks: https://www.sonarworks.com/reference/downloads/win
Sonarworks has speaker calibration that is swell too but it needs a calibration microphone 
thanks
sabaj da3 arrived. sounds real good. sounds better than the LKS to me which is just downright weird. i listened the few hi rez albums that i have.
mark knopfler shangri la which is 96khz sounded good
Tchaikovsky souvenir sounds wonderful. it is the best it has ever sounded. it is 352.8khz PCM
i cant get the 3 dsd albms that i have to play.
regular red book sounds good too. this is no burn in. literally out of the box 30 minutes ago.
graham sash prison song is a harmonica driven little song that all ESS sabre dacs always fail at and NOS/TUBE always wins for me. but with sabaj it is sounding like my phillips NOS audio mirror dac but with an obvious quieter background and more dynamic. the songs sounds darn good.
Indian that dwells inside this chest by Kashmir is a low quality recording that i like (iut is 320kbps mp3) and that sounds good too.
i think its a keeper.
