I just ordered a pair of 12 db line level attenuators on Amazon: http://www.amazon.com/Harrison-Labs-Line-Level-Attenuator/dp/B0006N41B0/ref=sr_1_1?ie=UTF8&qid=1396570940&sr=8-1&keywords=rca+attenuator
My iCAN does not have gain controls, and the TDS202 does boost the signal. So these attenuators should help give me a more usable volume range on the iCAN. Simpler than selling it and getting the newer version with gain controls.
Speak to Avatar and ask them to send you a set of iFi attenuators.
Let us know what you think of them!
