Due to the unfortunate fire at the AKM manufacturing facility in Japan, we have a very limited supply of this item. We urge anyone interested in this item to buy it while supplies last. Despite our very best efforts to get these products to customers as soon as possible, the impact of the fire on AKM’s operations may cause shipping delays. The AKM supply volatility will not improve until the end of April 2021.

The K5Pro is an audiophile-grade DAC/Amp capable of accommodating innumerable listening circumstances for an ultra-attainable price. 

Audiophile-Grade DAC

The K5Pro utilizes the AK4493EQ digital-to-analog converter (DAC), a powerful, distortion-free chip that supports sample rates up to 32bit/758kHz and DSD512. Boasting a signal-to-noise ratio (SNR) ≥115dB and a total harmonic distortion plus noise (THD+N) rating of <0.004%, the K5 Pro delivers noiseless, velvety sound. 

Toggleable Gain Switching

If your collection of high-end headphones are armed goons, the K5Pro is Bruce Lee. With a tactile toggle switch, it can handle anything from IEMs to planar magnetics. Low (0dB), Medium (+6dB), and High Gain (+10dB) settings can adapt to any listening circumstance. 

The Swiss Army DAC

Think of the K5 Pro as the Swiss Army knife of desktop audio. You can utilize any combination of its six inputs and outputs (I/Os) to accommodate a variety of listening circumstances. Need a DAC to bridge the gap between your computer and headphones? You got it. Need a DAC/Amp to connect your turntable and active speakers? You got that, too. DAC/Amp for your iPhone? Yup.

All-Aluminum Body

No one wants an ugly DAC/Amp dragging down the aesthetics of their desk. Fortunately, the K5 Pro features an all-aluminum body that’s been polished, anodized, and sandblasted for a finely-textured shell that embodies style and strength.
