The Air Force V Premium employs a sub-platter system consisting of an inner-sub and an outer platter both precision-machined from solid aluminum alloy A5056, with a total weight of 7kg. The outer platter surface is black anodized with a gloss hairline finish that matches with the silver aluminum plinth. It features a tapered spindle and a “very thin” pad of anti-vibration material applied on top.
The table also offers a 2-channel torque switching circuit that adjusts torque until the rated speed has been achieved. Once the rotation speed is achieved, torque is decreased in order to reduce vibration. A DDS (Direct Digital Synthesizer) serves to digitally synthesize any waveform or any value of frequencies according to the output from the crystal oscillator

Rather than testing total harmonic distortion at full scale at 1kHz as many do, I prefer to understand what the amplifier is doing over a broader range of frequencies and at a more reasonable output level. So, I do a frequency sweep from 10Hz to 20kHz at 5 watts RMS into 8Ω instead. For reference, 5 watts will usually produce somewhere between 85-105dB sound pressure level depending on the connected speaker’s efficiency. I personally find 85dB to be quite loud for extended listening sessions. (I usually listen in the 75-80dB range for longer sessions to protect against hearing damage.) At 5-watt levels, we see that total harmonic distortion is dominated by 3rd-order products up to about 2.5kHz where 2nd-order distortion takes over. At 20kHz, distortion is about 0.04% which is very close to the manufacturer’s published <0.03% THD.

Turning the wick up a touch, the thrill of the orchestra at full speed in the Scherzo of the Fourth Symphony sees the RS150 start to let its hair down and party. Similarly, switching to something a little different in the shape of Tame Impala’s Lonerism album sees the hard-driving pop shown in the best possible light. From the thumping percussion of the intro to Be Above It, the music surges out with supreme thump and punch, carving persuasive instrumental textures without overly deconstructing the wash of sound. Pleasingly, the results appear to remain broadly the same regardless of whether music is streamed via the network, the internal drive, the digital inputs or as a Roon endpoint. The performance remains consistently rich, dynamic and rewarding with only that slightly soft soundstage focus holding it back in any way – and this only seems to be in evidence on particularly atmospheric recordings such as church-recorded choral (which can sound a tad dry) and simply miked jazz in reverberant studio acoustics.

Digging into my cabinet of tweaks I came up with enough 70mm square damping feet from Soundeck to put one under each corner of the subs and at each corner of the bridges. In the photo below you can see the footer excess protruding from the sides. The thickness of the sides of the bridge is only 18mm, so there is not much material to anchor a footer unless the sides are reinforced with additional material. Each Soundeck footer, however, could be cut to create three 70mm strips to attach under the length of the sides of the bridge. Even on the soft carpeted surface, this made a noticeable improvement with virtually no increase in speaker height.
