Solo streamer

@rvpiano my pleasure!

Glad to hear, you’re enjoying N200. Keep in mind, N200 is designed and optimized to take advantage of USB implementation in a DAC of your choice. I know you love your current DAC, my recommendation would be to try another DAC down the road to see if you can push the performance another notch or two, I am speaking this my personal experience, I went from EMM Labs DA2 to Merging and there was no contest, the Merging was on another stratosphere using the same source (N20). Merging DAC allowed me to appreciate Aurender N20 at much deeper level, it was like lifting a veil.
Cheers!

What model Merging DAC do you use, and/or recommend?

@rvpiano 

I own Merging +player (Roon player + DAC) along with +power and +clock. Both +power and +clock are optional module and further enhances the performance of DAC by itself. Earlier this year, Merging bow out of consumer electronics and focusing on Pro Studio gear. Their consumer gear are now under Master Fidelity,

I'm a month late to the party here but to:     

jazzman7 and @monowatcher,

Clock source can depend on the DAC.  Maybe not normal synchronous I2s protocol but according to my Owners Manual for Pointus II, "incoming signals are all stored, buffered, and re-clocked using the DAC internal clock".  

     So without a streamer, using USB from a MB Pro M3, streamed RadioParadise or ripped CDs, sound is very good (would probably be better with a DDC), but noticeably better is I2s directly from an OPPO 83 to the Pontus, whether 16/44.1, 24/196, or SACD.
