I have an Innuos Zenith Mark 3 & tried to do the update but it froze up during the process & the unit wouldn’t boot up at all., contacted support & they were quick to respond, set up a personal time to live chat & logged into the unit & oversaw the update. Took less than one hour & & has worked flawlessly since then w/ a noticeable improvement in overall body & weight to the music w/ a Border Patrol DAC, Rogers High Fidelity integrated amp & Volti Audio Rivals.
I really like the Innuos & proved to have excellent customer support! Highly recommended!!!
