Decided to start a new thread focused on the Spring 3 and not the May, since one of the May discussions had spiraled out of control.
I only have about 100 hours on it and haven’t fiddled with anything - just slapped it into place where the Black Ice DAC used to be and hooked up the Jay’s Audio transport using the same cable. My first impression is it is a massive step up from the Black Ice in my system. So much more detail and clarity especially in the bass, space between musicians, hearing things I’ve heard before on albums I’ve listened to dozens of times over the past 30+ years. This could be an end game DAC for me. (Who am I kidding? I want Al’s Gryphon DAC but will need to search change under the car seats!)
I’ll probably give it another week and then switch out cables to use I2S. Will keep those interested posted.
