@nyev no intention of installing any reclockers or power supplies. I use LessLoss Fire Wire 640X on my DACs and digital front ends as well as analog. Also with the LessLoss Echos End DAC there is no need for any digital tomfoolery nor with my 680D. I am not an advocate for external clocks and every one I have tried has a truly made an organic DAC like the LessLoss sound muffled, vailed, like my ex wife biting a pillow.
Not saying the Phoenix is not helping your sound, it may be showing the shortcomings of your inboard DAC and it’s clocking ⏰ 🕰
