Design & Build Quality
First of all, SP400 is not a small amp it will occupy some space on your desk. It has a square form and you can use it to your advantage by placing your DAC on top of it. For example, my hefty Gustard X16 can stay on top of it without any problems. The SP400 has a glossy, plexiglass top cover and the rest of the unit is matte black CNCd aluminum. I like the design of the device as it looks quite handsome with the glossy top cover but I must also say that it is a fingerprint magnet. It is of course, nice to see SMSL exploring new design options. The device looks and feels durable and I must say that it is not a light device at 1.3 kilograms. Similar to the rest of their line-up, it is quite obvious that SMSL built this device to last many years, serving you and your ears. Additionally, it shares the design with the M400 DAC. Lets talk about the device layout.
On the front, we have a 1.9-inch color TFT display. Theyve used the same display on their other devices as well, including the SH-9 we reviewed a while ago. The screen shows info about the volume level, gain, and active input. We also have a volume knob, which offers 100 precise steps. The volume knob also acts as a navigation button and it has a small button on the center of it. The detailed menu can be accessed via the included remote and were going to be talking about that in a short while. Overall build quality is, as with many of the SMSL products, very good and my eyes cant spot any imperfections such as CNC milling defects or assembly issues. Everything looks perfectly in place. The volume knob feels accurate and durable, the sockets on the front feel solid and sturdy.
Technology & THX
The SMSL SP400 utilizes THXs AAA-888 technology. So what is THX and why is it beneficial to a headphone amp you may ask. Lets answer those and clear the fog. First off, THX is an American company founded in 1983 by George Lucas and headquartered in San Francisco, California. The same George Lucas who created Star Wars. THX was developed by Tomlinson Holman at George Lucass company, Lucasfilm, in 1983 to ensure that the soundtrack for the third Star Wars film, Return of the Jedi, would be accurately reproduced in the best venues. The THX system is not a recording technology and it does not specify a sound recording format: all sound formats, whether digital (Dolby Digital, DTS, SDDS) or analog (Dolby Stereo, Ultra Stereo), can be shown in THX. THX is essentially a quality assurance system. THX-certified theaters provide a high-quality, predictable playback environment to ensure that any film soundtrack mixed in THX will sound as near as possible to the intentions of the mixing engineer.
