Hi guys, I am planning to get an Apogee One interface and PreSonus HP4 headphone distribution amp to do some small scale multi-track recordings. I am looking for a Y-cable to connect the 3.5'' audio output of the Apogee One to the 1/4'' L and R inputs of the PreSonus HP4 so that both my talents and myself can monitor the take during recording. Any suggestions on where I can purchase a 3.5'' to 2 1/4'' Y-cable?
