Sounds like you have the N130. I have the same. I added the LHY linear power supply ($300 including shipping) which make a big difference and then added a tube DAC. Sounds amazing. I use USB to take advantage of the DACs clock. COAX did not sound nearly as good. I use all Zavfino cables. I listen to digital a lot more now than I used to. A real bargain compared to my analogue source. Details in my virtual system.
External DAC?
My question is am I going to improve sound quality by adding an external DAC to a Blusound node? For example, a SCHITT BIFrost and what is the best connection method? And another question to ask is about usage of my Bluesound node …just being a Streamer? Am I losing anything by doing it this way? Thanks
