Hi @slingshot, welcome to the forum. Not sure if you’re looking for a Holo DAC, if yes, I listed mine
here yesterday.
I haven’t heard the TT2 + M Scaler combo but I do have the Dave + M Scaler combo and I’ve fed the rig with DSD256 files and they sounded great after the up-sampling process. I did enjoy the sound of the Holo Spring DAC when feeding DSD files a bit better than Dave+M Scaler, it could be because of the R2R topology sweetness and just personal taste preference for the analog signal output of DSD256 files from the Holo. Please note that I’m not saying this to promote my listing, I’m sharing my honest opinion and experience.
