I purchased a PS stellar DAC to replace my Schitt Bitfrost w/multibit DAC.
I was looking to upgrade my DAC plus purchase a headphone amp and this fit the bill. As a bonus it had a preamp which I assumed would be an upgrade to the preamp section in my 10yr old LFD MkIII int. amp.
So to my ears the DAC section was an upgrade over my Bitfrost thanks to the option to select from 3 filters, the headphone amp is very-very good. As for the pre-amp section it could also be consider an upgrade due to the ability to select a filter.
The bonus was now I can control my music through the remote which the LFD does not have.
I am very certain there is a significant improvement over TIDAL FLAC files streamed through my Auralic Mini. I am not sure why, but the improvement streaming TIDAL through the Bitfrost is more obvious to my ears compared to the relative marginal improvement of Redbooks between the 2 DACS.
