Okay, so the guys at voodoo lab were great! They picked up my iso-5 and ran it through all of the tests, only to find that it was performing within design parameters. They said that they adjusted this and tightened that and sent the unit back to me. On some Timefactor settings I cannot detect a sonic difference between the iso-5 and the TF transformer, however on others I swear that I can hear a difference in the sound. How can this be?
