I’m also a huge fan of IsoAcoustic and deploy OREO for my DMP transport well as my MAKUA preamplifier. and OPPO 205 Blu-ray player. Mola Mola advises against the use of any accessories for use with their DAC.
At the end of the day, I’m not a particularly huge fan of DSD files, so I can certainly live with the way my DMP player performs such as it is. It’s superb and certainly better than streaming even in high resolution files. There is still magic in spinning a disk after all these years.
