About to compare a microrendu/ schiit eitr combo to a cxn streamer dac in my chain . Now go from my computer's ZXR sound card w optical out to a cambridge cnx streamer /dac then coax out to a gungnir dac( has no usb connect, just coax & optical in). Gungnir dac out to ead ovation preamp to ati 1505 (180 watt all channels driven) amp to thiel 2,3 floorstander speakers. My cnx is a new addition but I was disappointed that my 12 year old music hall cd player's sound is superior to the ZXR sound card/cxn/ hi res flac sound, so il try the microrendu. Aggrivating that I could not find a definitive answer to the "what better connection/chain" in my research. An expensive lesson, since I'm not sure if the microrendu vs the cxn streamer/ dac in my chain is an either or but not both choice? Expect I will save up & do the $550 gungnir/gumby update. not sure if I should also install the usb $100 gen5 card. Need to learn more about usb related tradeoffs & better sound. I have no experience using a lan ethernet connection or usb connection for music. Previously, I went from the XLR sound card out to a integrated onkyo amp, but the xlr has a 6 channel out(front,rear,center) or toslink optical out, not really meant for connection to a schiit stack or onkyo integrated.Or, with limited exposure, so I then thought. Disappointing, since the sound card probably did a better job than the eitr in cleaning up jitter, timing & fuzzy sound. Thus, my dilemma. Comes done to a $600 to $1000 lession in the merits of what connection- coax 192, optical 96, ethernet/ usb, is a better sound. And if both the microrendu/ eitr and the cambridge cxn should be in my chain together? This all started 10 years ago when the sound from my computer's $250 xlr sound card + $500 5.1 logitech speakers compared favorably to my way more expensive main stereo system. We needed only flac type master files. I could see then that a tidal type file playback was potentially easier than loading one cd or one vinyl record at a time. But I didnt wish to forgo better sound in the process. Just wish those that already have gone down this path would share the knowledge & opinions. Im new to superbestaudiofriends so perhaps I can learn & share here. Please help Should have a few good youtube videos out of our experiences from all this.
