I am using the Emotiva A-100 amp in direct drive mode. Its stock mode has two dropping resistors of 3 watts that reduce the power of the amps output and increases its impedance to 220 ohms.
I prefer the sound of the amp when it is in direct drive mode without these resistors.
My Sennheiser HD 600 had no problem with this amp with its 300 ohm impedance. However my HD 700 headphones have a noticeable hiss with them with its 150 ohm impedance.
So my question is - is there some adapter I can use - (NO SOLDERING OR ELECTRONIC SKILLS) - that would increase the perceived impedance of the headphones to 300 ohms? So that the A-100 sees a 300 ohm load instead of 150 ? I hope to use this solution to decrease the hiss.
