I've playing my ipod thru my Rega Brio 3 amp using a cheap 3.5mm to RCA cable and a pair of Totem Rainmakers bookshelf speakers. When I play some dance music for example A New Day - ATB or Stereo Love - Edward Maya, the beat suddenly got faster. I've listened to these songs hundreds of times thru my headphones and on my computer speakers. Also, I'm using 2 feet of Chord Silverscreen cable with banana plugs. It is only noticeable with dance music, not too much with other types of music. Now my dance sound weird with the increased rhythm. Anyone here know what the heck is going on?
