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.

Thank you for the reply. I have something else to point out (sorry for not doing so initially). This particular amp uses a motorized (presumably) pot volume control. I assume this because it is moved when the remote control is used. Might it be noise introduced by the motor (because that is in use whether moved manually or via remote) and if yes, would that be considered normal in amp in this price bracket?

In general, you should not have any noise associated with motorized volume controls regardless of price point.
We have <$2,000 preamps with motorized controls and there is no noise at all. You might want to contact MF or the dealer.

Musical Fidelity is now made in China.
Lots of lemons there.

If the static was induce by the motor it would happen all the time just not when playing "Test Tracks"

On the other hand it may not be an issue with the Integrated, it could be that the CD players you use can't decode/filter the particular tracks. Does the particular issue happen only with this integrated or have you tried it with other amplifies as well.

But, how important is this really, I presume you bought the integrated to play music, not test tracks- so why worry about it.

Good Listening

Its a brand new piece. He shouldn't have to live with a problem like that on something brand new. Also, if it does turn out the volume pot, it will only get worse over time.

No. You shouldn't have that problem regardless of cost.
