TASCAM US-100 USB Audio Interface

I had the two-channel version (US-122) before upgrading. The preamps were noisy and there was a lot of interference between... well everything. Anything playing through the main outputs was recorded, at a very low volume, onto whatever I was tracking. This was obviously incredibly annoying.

The one-channel version may be better, but don't expect high quality.

Anyone else have the same experience?
