I just purchased new T1s without having a suitable amp (looking for deals), so I just tested it with my home audio receiver. I'm hearing massive distortions and rattling (maybe buzzing?) in the right channel that's not present on either my stereo or AD700s. The left channel sounds fine. I'm sure about the specific frequencies, but I played an "audio test sweep" from 20hz to 20khz and it seems most noticable around the mid range.
Does anyone have an suggestions or recommendations?
You are, in fact, hearing your receiver.
