The M8-700 has received outstanding reviews and an enthusiastic reception from knowledgeable audiophiles. The combination of high power and cutting edge technical performance has proved a compelling combination. However some customers do not have the space for two large monoblocs and do not necessarily need that much power. For them we have designed the M8s-500s. Pairing it with the matching M8 Preamp gives an amplification system fit of the highest levels of reproduction.

Design + Build

The M8s-500s is a fully balanced stereo amplifier which delivers 500wpc, which almost doubles into 4ohms. The M8s-500s is engineered for very low distortion typically less than .001% of 1kz and below .005% at 20kHz. Even at the ridiculous level of 50kHz distortion is a mere 0.02% creeping up to around 0.06% at the even more unreasonable figure of 100kHz. These may be measurements of frequencies never encountered in the real world but they prove a point; that the M8s-500s significant less distortion than rival designs.

Like the M8-700m the M8s-500s has very low noise. Its combination of huge power reserves, low distortion and low noise contribute to its effortless performance. It delivers everything from delicate detail to massive dynamic slam with incredible speed and precision.

Whatever style of music you listen to the M8s-500s serves it up in a spacious sound stage with outstanding realism.

Its power and balance mean that the M8s-500s can drive just about any loudspeaker you choose. It is, of course, the perfect partner/visually and sonically for our M8 preamp.

          Good bang for the buck.
          Color: 2Pcs 18W LED Flood Light
          I have bought 10 of these now. I put them on my work trailer and use them for reverse lights. They are cheap, easy to install, and they work very well. Now and then, I break one; they are exposed on my trailer and stuff happens, and these are so cheap it's not a big deal to replace them.

          used for a snowblower light upgrade
          Color: 2Pcs 18W LED Flood Light
          I replaced the halogen bulb that came with my snowblower with these bad boys. Talk about a night and day difference! I was able to use two existing holes on the top of the blower and the included brackets to mount them. I also had to get a rectifier that converted the AC 24V to the 12V DC these expect. Used some scrap conduit, wire loom, and some project boxes to bring the whole thing together. Now the light is a lot brighter, and it's not half-blocked by the chute. Big improvement! You can find plenty of howtos and parts lists on youtube to do the same.

          use care when starting the bolts.
          Color: 2Pcs 18W LED Flood Light
          Had these for awhile before I got around to installing them or should say attempted to install these. Mounting the bracket was challenging with supplied bolts. The predrilled holes in the mounting block were very poorly threaded. It was almost impossible to get the bolts started without cross threading. The finished product was acceptable. I have other Nilight products and never experienced a single issue.

          Best lights you can get for the best pricing!
          Color: 5in Round LED Pod, Color: 5in Round LED Pod
          I have had man different off road lights over the years for many different vehicles. Let me tell you about these 5” aux beams. I ordered these lights to go on my 2500 as ditch lights and I am beyond impressed! The lights showed up well packaged. When opening the box, the instructions where right on top and by far one if the easiest sets of instructions I’ve had for wiring diagrams. The lights were packaged and wrapped in foam all the way around to protect them from shipping. The wrapping of the lenses for scratch prevention was perfect. The included wiring harness was packed in a bag and laid out very easily for installation. The harness hooked to the battery and then to the lights with easy quick connects and had more than enough length to put the lights anywhere. Once they were mounted and installed I hooked them up to my aux beams switch panel with ease. Now for the lights! The brightness is beyond bright enough to see miles away! These lights will shine anything you could ever want to see. The spot flood combo work exceptionally well for all situations and darkness. The side shooter stretch them beam out to the sites and can see all the way across. The running lights tie in very easy with your turn signals for extra turn lights or running lights. Heavy duty is an understatement for the quality of these lights. I’m still running them after several months with no water intrusion and still as bright as the day I installed them. The price for what you get, is far beyond better than other top brands! I will be buying more of these for my next off roading set up!
