This is good performance but can't keep up with our desktop products that are optimized for 4 volt output:įortunately performance improves if you allow higher output levels: Sorry about that.Īs noted, I used Roon to play my reference 1 kHz tone and measured the response using the Monitor outputs adjusted for 4 volts out: Since there is no other digital input, I could not fully test the ADC. I had to use my Roon player for a bit of testing using TB and then Toslink for the rest.
