Mamoritai Audio Euphony

The package begins with a large box containing the Euphony, a cable, and a silver badge as an alternative to the gold. A manual is also included. Honestly, I was slightly disappointed that no RCA cables were included given the price, but fortunately, I have some excellent silver ones from ddHiFi.

The Euphony is a high-tier amplifier from Mamoritai Audio, an upscale brand by Fosi Audio, renowned for their sensible and well-built electronics. It boasts ample power both as a headphone amplifier and a preamplifier.
The device is quite heavy and completely chrome-plated, which gives it a stunning appearance but also makes it prone to fingerprints.
The design stands out because it features dual 6.35mm headphone outputs on the front, which can be used simultaneously to power two sets of headphones. I would have appreciated more I/O options on this device, such as an XLR or at least a 4.4mm balanced output. It only has one set of input and output RCA on the back. I own a few similarly priced amplifiers from Burson that offer several options. Despite this, it is a well-made device, although the I/O is just me nitpicking.
The knob is large with a smooth turning radius, which is aesthetically pleasing, though preferences may vary. Personally, I prefer a stepped, clicky volume knob. The power switch is located on the back, akin to my EF500, which somewhat limits placement options, but it's not a dealbreaker.
Having used the unit for some time, it remains cool under normal loads, which is remarkable given the lack of venting. It's possible that the sides act as a radiator, which is quite intriguing.

Sound
This robustly constructed headphone amplifier delivers a pleasingly smooth and sophisticated tonal quality, with a pronounced emphasis on spatial detail, all within an expansive presentation. The headphone amp is surprisingly neutral with little to no coloration, yet it delivers great dynamic response with full-range vocals and an airy treble response.
I would describe it as an exceptionally precise and smooth amplifier with a linear volume curve, providing great detail, a gentle response, and ample headroom.

My thoughts.
The term 'euphony,' defined as the quality of being pleasing to the ear, truly lives up to its name. It is very detailed and without sharpness or harsh spikes. It possesses ample power and, with its impressive appearance, may come across as somewhat ostentatious and grandiose. You can be confident that it matches the grandeur of its hotrod, chrome-plated exterior.
