About this deal

Trying to find the right headphone amplifier for your needs can be tricky – especially if you don’t know what to look for.

Because of the aging of the power supply, there may be an abnormal power supply resulting in white noise. Before getting into the review, I have to say that I was surprised at the details that Fosi share about the product. Added to this we have a bit of background hiss which becomes apparent with sensitive IEMs when moving past 50% on the dial, with 75% being audible on almost all IEMs and headphones. Giving the knob a short press allows you to switch between the setting menus for you to adjust features to suit your needs.

I threw quite a few of my headphones at it to see what would stick and it was able to drive all of them to uncomfortably loud listening levels, even on my Hifiman HE-500 and Sennheiser HD650, however it struggled to render the sound competently when compared directly to more powerful amplifiers.

Features: Supports MQA decoding; The top performance D/A chip ES9038PRO from ESS Technology; The high-performance power supply chip ES9311, the noise of ES9311 is as low as 1uVrms, to push ES9038PRO to the limit; XMOS XU-216, true 32bit audio processing, supports DoP and Native DSD, and reaches. I enjoy him and I find some of his videos worth the watch, but I think that if either of the units he thrashed above were US made, then he might have something different to say. NOTE: Due to different TV types, some TVs default Dolby or DTS sound output, Q4 DOES NOT support Dolby and DTS sound, please select RAW/PCM sound; otherwise, you will hear a lot of noise or no sound output. I would HIGHLY recommend trying to get the budget for a Schiit Fulla or Fiio K3, that or just run onboard audio, it's far superior.If absolute peak audio quality isn’t a concern, even to seasoned audiophiles who just need a small, affordable and versatile unit for their gaming console, this is certainly an option worthy of consideration. If you are troubled by TV sound being out of sync with the picture, the Felston DD740 provides two additional Toslink inputs while fixing the sync issues. The K5 pro sounds clear and transparent with a slight warmth and very good details, it is a vast improvement over standard audio from the source, Nintendo, PC, phones and PlayStation. Of course this evaluation only takes into consideration the units performance when no tone control is applied.

Mine was perched a little higher off my desk on the edge of my monitor stand base, so that was a non issue for me. It can be used as a preamplifier or volume control for PC/MAC/Computer with bass and treble controls. TB10D 2 Channel Class D Power Amplifier Bass you can feel, a mid-range that is crisp and clear, and a high that is sharp and precise. I know some people will wish it was made by a western manufacturer with fancy letters in the logo and have a cost of a few thousand dollars. Usually we find the most basic of specs published and not much else, yet Fosi actually list the chips used and the THD, SNR, etc.Mini Compact D/A converter, stream bit-perfect 24bit/192KHz HD with low jitter, with output, protect the circuit, safe for your expensive audio system.
