Pure Music distotion


Recommended Posts

Two questions when using pure Music I hear some mid to bass distortion. When just iTunes it goes away. I hope its not the ifi nano. I have volume max on iTunes and ifi nano and controlling it with my B&K preamp. Im going into the inputs on pre amp for CD. Is that correct. When I listen to the music on my old Mac Pro 2009 thru a MOTU interface and use pure Music it very good.

The Nano might be the issue. Back off the gain to see if it is the issue.

Just mentioning that there's a new iDSD Nano firmware out. Make sure you update your firmware (not saying this will resolve your particular issue).

I did that and no help. How about the little switch in back titled Minimum Standard" I don't understand what it is for?

nano – iDSD

 

This is for the filter type. Spend some type reading a few reviews and you'll get a lot of info on how it operates.
