Hi,

I have a SimAudio I5 integrated amp connected to KEF Q7 Speakers. I
notice that there is a slight hum in one the speakers. Any ideas how
this may be caused and could be eliminated. I tried the following with
no difference in the hum

1. Provide enough seperation between power cord from the speaker
cables
2. Line filter
3. Interchanged the speakers
4. Tried without connecting any signals to the amp (removed all input
cables)
5. Send mail to SimAudio and they asked me to connect line filter

I had auditioned NAD, Rotel amplifiers and did not see any hum from
them. Also, I find the hum is more in the right speaker.

I am using good quality interconnects and speaker cables (straight
wire). My source is only a CD players and the hum is there regardless
of whether it is on or off

I see the hum in all of their amps such as I5080, I3

Any ideas please let me kow

Thank you
