    Montis + NAD = bliss with issues

    I realize I may have committed blasphemy in the eyes of some here, but I decided to go with a pro amp, the QSC RMX4050a ($1499). I concluded that there are very few amps made under $1500 that can fully drive the Montis. According to ML, the Montis get down to 0.5ohm impedance at 20KHz which is...

    Thanks everyone. I just got an email reply from Roger Sanders with a detailed technical explanation of my system and inherent problems. I think everything you guys have said is aligned with what he said. So I need a powerful amp that doubles down as the impedance drops. Since the NAD is an...

    Montis + NAD = bliss with issues

    Ken, I do have another amp but it will be a few days before I can swap them out and take measurements. I may also see if the bump and dropoff occur in different parts of the room, or if speaker placement affects it. I used the poor man's method: Radio Shack meter and sine wave test tones...

    Thanks Jonathan and Edwin. Here are the specs for the NAD. Continuous output power (ref. 20Hz – 20kHz, rated THD) - 8 ohms ≥150W Continuous output power (ref. 20Hz – 20kHz, rated THD) - 4 ohms ≥150W Rated distortion (THD, with AES17 and AP passive 20kHz LP filters) <0.005% (ref. 20Hz – 20kHz...

    Montis + NAD = bliss with issues

    I am the proud new owner of a pair of Montis. Paired with a NAD C390DD, the sound is superb. I do have 2 issues though: The NAD will shut down with a "channel protection" fault when playing high frequency or busy pop music at moderate volumes (as low as -23db in certain passages). Did not have...
