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

HTA5200. Class A/B, no-frills, monster among beasts. It looks menacing in the best way. Using 4 of its 5 Amplifiers to power 4 of the beautiful Klipsch RF7-II Tower's (8ohm 250w Continous). I mainly listen to very busy, intense, high bitrate music w/ deep and unrelenting subsonic bass. The OSD Nero HTA5200 is up for the task. It'll easily handle the less demanding cinema signals. All of the connections are robust and feel very firm. Trying RCA and XLR to compare and because I'm an idiot and two of my patch cables are too short. Can't tell any difference in quality. If there was a problem with noise introduction or distortion, I'd know. It would be very obvious when connected to the Klipsch towers because they are so sensitive/efficient. 101db @ 1m / 1w.

I also bought this due to Youthman's youtube channel special code that day. This is replacing a 25 year old (still working) Anthem Statement A5, 5 channel power amp. Thinking it's just a matter of time before the Anthem gives up the ghost, I've have been pondering replacing it before that happens. When I saw this on YouTube, it was a no brainer and I went for it. This thing is so well built and is actually heavier than the much more expensive Anthem. It sounds amazing but only time will tell whether it will have the long-term reliability of the Anthem. Again, the build quality is simply amazing for the price, even without the early adopter discount.

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.

If You have surround sound AV Receiver you need pre-outs or get the Pre-Outs this will push your 8ohms or 4ohms Speaker 🔊🔊 to reference levels to mirror the Moive Theater. This is a must have for the price . Atoms & DTSX lovers you love this for your height speakers and your Front Stage ❤️❤️❤️❤️💪🏿💪🏿💪🏿💪🏿

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)

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

I had a Marantz 5 channel amp that developed an issue with the first channel, and given current economic conditions I was loathe to invest in an expensive 5 channel amplifier. HT is not stereo and I felt no need to purchase a class a solid state or some other high performer. I was also unwilling to swap from XLR to RCA and found this amp on Amazon. Performance wise it exceeds the nearly double the cost Marantz that it replaced. It drives an 86db/1 watt 90 lb center channel without so much as getting warm and if there's noise, well... I can't hear it. AB amps in this day and age should not be rocket science. This amp delivers. I feel like I robbed someone.

This amp really upped my listening experience. Using my Marantz SR5015 as a pre-amp\processor, , the sound-stage is much fuller and and I can now play at reference levels and have virtually no distortion, clipping or compression. Whole new experience. Good job OSD!

Super great sound. My home theater sounds more clear you can hear the voice perfectly as if you are inside a big cinema

Super ampli, fonctionne très bien. Livraison rapide.
