OSD Audio Nero HTA5200 Multi-Channel (5X) 210W/Ch Home Theater Amplifier

Super ampli, fonctionne très bien. Livraison rapide.

No power chord included. 12v trigger chord included, but only about 12 inches long. All hookups done with power off. Tried rca hookups first (KImber pbj interconnects). One channel had mild hum but no music. Second channel had music and a LOUD hum. Channels 3,4,&5 played music with a mild hum. Was ready to send back, but decided to try xlr cables which arrived the next day (Mogami/Neutric). First, covered the rca’s with Cardas rfi caps to block the hum. Music now comes from all 5 channels, no hum, and integrates well with my Vincent SA-500 integrated powering my front Klipsch Heresy main speakers and RSL-12 sub (7.1 system). It seems OSD has perfected the class H amp for home theater use when utilizing xlr hook-up only. The rca hookups are as useless as tits on a boar hog. I’ve decided to keep this unit anyway.

VERY WELL BUILT ...I SAT ON IT PUTTING MY WIRES TOGETHER..SOUNDS GRWAT ALSO..

So far my experience with this amp has been slowly driving me a bit nuts. It has some power to it and makes the audio come alive but the power filtration or whatever they use (or dont use) is making all sorts of noises come through my speakers. Unfortunately I'm probably going to start thinking about going through the hassle of sending my amp back. Pros: -great sounding amp -good power for the price -xlr and rca inputs Cons: -reliability is definitely questionable -very noisy amp (hum, buzzing and squealing)

I tried the OSD Nero XMAX-11 for about a week in my home theater (11 channels, external processor, multiple subs), using RCA connections. My unit had a serious problem: the AMP 8/9 module repeatedly shut down during movie playback, especially during dynamic scenes — even at moderate levels (around –10 dB on a Denon X3800H). Once it shut down, the channel stayed dead until the amp was fully power-cycled, which strongly suggests a protection fault. I swapped speakers, inputs, and wiring, and the problem always stayed with the same amp module. All other channels worked normally. In practice, this made the amp unusable in a multi-channel system. A few other notes: -The front display backlight is always on. You can turn off the meter, but the backlight stays lit, which is distracting in a dark room. -Customer service responded, but replies took several days. -Amazon’s return was easy, though shipping a very heavy amp back wasn’t fun. On paper this amp looks like a good value, but reliability matters more than specs. I ultimately returned it and went with a Monolith 11X that has been completely stable. Bottom line: Based on my experience with repeated channel shutdowns, I wouldn’t trust this amp in a serious home theater.
