M6X 250.5 | POWER AMPLIFIER

The M6x 250.5 is a 5 channel class A/B power amplifier.

You listen to CDs or stream music without picture, but have you ever watched a movie without sound? The sound of a movie carries a significant part to deliver emotions and tell stories. Silence is as important as bombastic loudness. Sound designers use sound effects, foleys and music to enhance your experience. A soundbar can never reproduce a real cinema feeling. The M6x 250.5 will take your home cinema to the next level.

The Full Cinematic Experience

For many people, the cinema is just a place with a big screen and expensive snacks - but there is more, which is usually not visible at all: The surround-sound-system. It all started with a simple three speaker setup in the 1980s and evolved to object based systems with up to 20 speakers. With the new M6x 250.5 you can easily create a powerful 5.1 home cinema setup (your active subwoofer is powered separately). You can connect your preamplifier/AV processor with either RCA or fully balanced XLR cables. The XLR connection furthermore enhances the sound quality and keeps the signal transmission clean.

The Musical Fidelity M6x 250.5 will not only satisfy you with its sound quality, but also with the high quality metalwork and overall clean look. The front panel, in either black or silver finish, is a custom-made fine line aluminium extrusion.

Connection

The M6x 250.5 offers a gold-plated RCA and a balanced XLR input per channel. If you have XLR outputs on your preamp, we always recommend using a balanced connection. This kind of signal transmission leads to increased dynamics, less noise and improved signal-to-noise ratios. If you need the same signal on multiple inputs for e.g., bi-amping, you can use the gold-plated RCA through output and distribute the signal to the next input. The gold-plated isolated speaker output terminals accept 4 mm Banana plugs, spades connectors or naked wire. The trigger in-/output allows you to turn the device on/off via other components.

Power

Our new multichannel amplifier is built modular with one 250W class A/B amplifier stage per channel. We designed our amplifier to sound highly natural by keeping all transients and micro information. The super silent audiophile power transformer distributes clean power, which results in a high dynamic range and a detailed sound stage. This is a major feature for a home cinema amplifier. The M6x 250.5 is able to preserve all the details and emotion, no matter which volume. Due to the sophisticated heat sink design, the M6x 250.5 does not need a fan to keep the amplifier cool. Despite its big power, you will never hear any fan noise coming from the amp.

Amazing fiberglass restoration.
So easy to use and fabulous results. A few years back I had tried Maguires products to restore the shine on a 5th wheel. That was so labor intensive and the results were struggled to achieve faded quickly. I hesitated to Poli Glow due to the cost and our prior attempts lackluster results. I was able to get the restoration kit at a discount on Black Friday through the stores website and tackled the camper with the temps between 60-90 as instructed. I bought 2 of those kits just to find out that due to the climate and UV exposure the number of coats I would need for the Poli Glow was going to exceed the amount I had on hand through the 2 restoration kits. So I had to scramble to buy another bottle of Poli Glow. Applying this product is just time consuming and not difficult. Make sure to properly prepare the surface before using poliglow. The whole system turn a badly oxidized camper into a shiny finish. I am truly shocked. Hopeful the results will last a while. 5th wheel camper 40 foot long. I have used 3 poliglow bottles (12 coats), 1 bottle poli ox, 1.5 bottles of Poli wash (of course, not in that order). I potentially need 1 more bottle of Poli Glow to finish nose cone/basement area (basement area is still in good condition so may not do this area if I can get the nose cone with the remainder of the Poli glow I have.)

Worth the time and effort.
After proper surface prep and 6 applications, my badly sun damaged RV shined like new, with many compliments. However, after a few months under the cover, the fiberglass surfaces that were in contact with the occasionally wet cover in the Florida sun discolored badly, and will have to be wet sanded and the coating re-applied. Also, the polish does not hold up well where boat fenders rub against the coating, and it wears away in cockpit areas that are heavy hand traffic, like hatchways and around handrails. Overall a decent product, I will probably re-apply in a couple seasons.

Brings old paint back to life.
Best product for fiberglass oxidation. Tried many different wax’s and compounds. Poly Glow did what the wax could not do.

Wish I Had Used This Sooner – Stop Debating and Just Buy It!
Size: Powder Poli Ox - Pack of 6
Wish I Had Used This Sooner – Stop Debating and Just Buy It! After a lot of debate, extensive research, and way too many hours spent using other products trying to restore and protect my RV's fiberglass that never fully delivered the results I was after, I finally tried the Poli Glow Deluxe Kit—and I am extremely happy I did. My only regret is not using it sooner instead of letting other people's opinions talk me out of it. The 6-in-1 complete kit is the right way to tackle fiberglass restoration from start to finish—eliminating oxidation, restoring the shine, and then protecting it long term all in one comprehensive system. The difference in how my RV looks after going through the full Poli Glow process is genuinely impressive and far beyond what any single product or traditional buffing method I tried before could deliver. The oxidation came off cleanly, the restored shine is deep and glossy, and the long-lasting protection gives real peace of mind knowing the fiberglass is shielded from UV damage and the elements going forward—especially important in the brutal Las Vegas sun. For anyone who has been going back and forth on whether to invest in the full Poli Glow Deluxe Kit—stop debating, stop listening to everyone else's opinion, and just do it. The complete system delivers complete results, and I won't be using anything else on my RV going forward. Highest possible recommendation.
