I recently bought a innuos Zenith MK-3 ,I have been into audio 4 decades and look under the hood on everything for parts quality ,
3 LPS power supplies not just Two ,throughout the chassis the feet iso bearing feet for top isolation ,inside very high quality Teac cd ripper ,their program is excellent and intuitive Sense app.CD rips sound excellent right to the Intel SS drive , the whole interior has isolation treatments on both drives and chassis , the Mundorf Mlytic capacitors are very $$ but well worth it ,you get a more warm perspective ,which I feel very natural ..get rid of the 50 cent fuse and put in a 20 mm Hifi tuning 3Amp ,slow blow supreme silver gold fuse $90 don’t break the bank and adds openness and detail , a good power cord highly recommended also for Digital by far my favorite Digital cables is Tubulus Digital Audio cables , Ethernet ,USB,As well as I2S the Only true I2S Solid core Air-tube dielectric Great cables make a very big difference to your digital Realism fo . My Denafrips Gaia DDC to Terminator15 Dac, Everything counts .also from your router a LPS a Must ,digital is not grounded and wall wart just adds more noise,
