Article: APL Hi-Fi DSD-MR DAC and DNP-SR Streamer Full Review

[barrows]

Thanks for the review Chris, it is interesting to hear about what AP has been up to lately, as mentioned by Ted B. he used to be known as a modder,  particularly of CD/SACD players.  I am interested to hear that he has fully committed to the DSD approach now, and I am finding (via a very similar DAC approach using an active, discrete FIR filter (thank you @Miska), followed by passive analog filtering using Lundhall transformers with DSD 256 input) that I also really like what a pure DSD conversion approach can accomplish, even with 44.1/16 source files (oversampled to DSD 256 in software in my case).  While I am certain that every detail of this DAC contributes to its sound quality, I would submit, that from my experience, the biggest factor in the sound quality is the "pure" DSD conversion engine running via discrete components.  For those who balk at the price of this DAC, I would suggest auditioning one of the "pure" conversion style DSD DACs available from other sources.

Bricasti's M3 for example, or Denafrips, or Holo Audio, and oversampling in software to DSD 128/256.  While HQPlayer is likely the very best option for this, ROON alone offers very good oversampling to DSD as well.
