I read in an earlier thread about skipping the output resistors on IVY when connecting phones. I wired my balanced phones to the input side of the resistors, and the result was really great. I perceived a better sound. My question is if I can jumper the output resistors also when connecting to my Hypex Ncore400 amp? I use short wire inside the same cabinet. I would appreciate some expert advice here.

These are the Ncore400 audio input characteristics

DM Input Impedance 104 kO
CM Input Impedance 1.5 MO
CM Rejection Ratio 55 dB All frequencies
Bias current ICM +/- 200 nA Inputs shorted together, sum measured to GND
Offset current IDM +/-3 nA

Ok, no answer to this one. I tried it out and connected the IVY to the Ncores without the output resistors. It worked fine. I perceived the sound as cleaner and more direct. Please inform me if this is not an advisable thing to do.

Sorry I missed this, yes usually you can usually use a jumper there. Only if you have extremely capacitive load are they really needed.
