I have recently started to buy music from HD Tracks in AIFF format. I do this to play music at home on my (MacMini/iTunes/Audirvana Plus/DacMagic Plus/NAD amplifier/Monitor Audio) stereo system. iTunes match will not accept these files and they are not available for me thgrough iCloud. This is a major problem. I understand that others have made the same experience. Please Apple, solve this problem or iTunes match will loose its purpose for me.
