This bundle consists of the following items:
Enjoy the sound, style, and convenience of a headphone amplifier with Bluetooth®, RCA, and USB inputs. This hybrid tube amp combines the warm, soothing sound of a tube preamp with the efficiency and clarity of a solid state headphone amplifier. Connect your computer to the USB input to use the 24-bit/96kHz Digital to Analog Converter (DAC) to stream WAV, AIFF, FLAC, other high-resolution lossless audio files. Stream your digital music to the amp using the built-in Bluetooth 4.0 radio with the superior sound of the Qualcomm® aptX™ audio codec or connect an external audio device, such as a CD player, to the RCA line inputs. Connect a pair of powered speakers or an external amplifier to the preamp outputs to share the high-quality tube sound with your family and friends. Not only does this amp sound great, it looks great, too! The black panels, chrome accents, and the warm glow of the exposed tubes present a minimalist retro look, which will enhance any home or office environment with a hint of old school styling.
The Monolith M560 planar headphones are the perfect way to experience your music collection. Clarity, detail, and balanced sound are all hallmarks of a planar driver. A unique feature of the M560 is that you can tailor the sound to your taste with the ability to transform the headphones between an open or closed back configuration. Engineered for maximum comfort and durability, the Monolith M560 offers a premium audio experience.

The amp looks beautiful to start it off, the functionality has been compromised a bit. Connecting the amp to my computer via USB would often lead to connection drops, unplugging and re plugging the cable solved it. This happened way too often, turning my light or fan on/off would make it drop signal, making it unusable. A simple fix is running it through the pre-out of a separate DAC which I happened to have laying around. Connecting it this way makes it feel a little less legit, but the sound is still spectacular, nothing more I can say about it sound-wise really. Bluetooth works well, though not tested it at big distances. The only thing I didn't enjoy about the amp besides the USB port is the extremely sharp edges at the back BEWARE! All and all it's worth the money, it helps if you have a DAC just in case you also experience a janky USB port.
I want to just glare over the fact these are built like a tank and look too good to be an inanimate object. however I don't want to neglect it.
Out of the box the cans sounded harsh, I could barely listen to them when open. This cleared away after about 6ish hours of use (I really don't know if it's 6 or 12 hours, just saying it gets better)
The headphones are also very loose, be careful headbanging, or really doing anything without losing them. You could bend the headband a bit, but this seems pretty risky. Instead I got some thicker pads. SONY MDR XB 500 pads, which are about 1.5x the thickness of the stock pads. There is no mounting system available for the pads, but nothing some double-sided tape can't fix. This for me fixed the clamp issue. Mad props to my large head too.
When used open the headphones sound very ''big'' which is nice. When closed they sound kind of held back. I figured the sweet spot for me personally was somewhere in the middle.
I tested with 1, 2 and 3 washers between each earcup and wooden cover. It was pretty clear to me then that three washers worth of space between the cup and cover was holding back the headphones from being perfect. I glued the washers together, wrapped them in a layer of electrical tape. Done. The M560's are now perfect.
I'm happy I sold half a liver to pay for shipping to Europe. Very satisfied about the packaging, making it very hard to get damaged. US>EU in 4 days is very much worth not being able to have a drink anymore. Jokes aside I'm very happy about my purchase. I hope MP looks into the USB ''issue'' I hope for others sake it's just my unit. I'd love for the magnetic pad parts to be sold separately so you can swap pads without salvaging stock pads.
Monoprice please send me pair of M560 so I can make my Sony pads magnetic. <Just jokes, but don't feel bad if you do.
