Normal or Abnormal?

I have noticed the following problem with a BRAND NEW Musical Fidelity M6si. When a Denon Audio Technical CD C39-7147 CD is played tracks 46-53 spot frequencies on two different CD players (Emotiva ERC3 and Sony DVPNS57P), regardless of XLR or RCA input, and the volume control is raised or lowered manually or via remote, significant static is heard. I also ran same test via USB input from https://www.youtube.com/watch?v=d3hTyKlza2c

Those with the M6si or better are asked to weigh in on the question as to whether or not "static" is heard when playing spot frequencies and adjusting volume up or down.

Why do you emphasize the playback of tones? Is the effect masked by music if you play music?

I would say if you can hear any noise with a line input (not a phono input) you have a problem. Most modern gear will be dead silent, even with your ear near the speakers. Unless, of course, you have extremely high gain somewhere in the chain.

I would return to the manufacturer and have the unit checked out. Audible noise should be easy for a tech to measure.
