While the soundstage isn’t huge, it’s definitely not restricted in any way. It’s not especially wide but it has excellent depth and I can easily guestimate the relative position of musicians in relation to me. It reminds me somewhat of the Topping DX3 Pro Plus, with its precise imaging and clean instrument separation. Verdict In the beginning, it boots immediately upon plugging in but it can remember to start on standby the next time if preferred. For a device this small, the SMSL C200 is quite versatile and offers a lot of input and output options. Not only can you use USB, but there are also optical and coaxial ports as well as Bluetooth. Speaking of which, you get Bluetooth 5.0 connectivity with SBC, AAC, aptX, aptX and LDAC codecs, which makes the C200 able to deliver great sound quality even without using the wires. You can select both the input and the output, though you can’t differentiate between balanced and unbalanced (and that’s reasonable). All testing was done with an SMSL HO100 and Earmen ST-Amp amplifier, combined with a Sennheiser HD560s and a HarmonicDyne Athena for headphone choices. Summary

high-end dual op-amps OPA1612 and a large number of audio grade components are used while there is a built-in specially designed low-noise switching power supply and a discrete component linear power supply with multiple low-noise power supplies for the analog and digital circuits. Measuring 12 x 16.8 x 5.5 centimetres, we can say that the K7 is “compact” for an all-in-one device. Let’s take a closer look at what FiiO has changed and improved with the K7.With a sturdy portrayal of notes as they happen in a well-defined bearing, the C100 is skilled enough to be used with less worry that instruments stumble their placement. How the C100 has been tuned though causes certain regions to be emphasized which somehow affects evenness.

Damage due to user negligence, accidents, disassembly, waterlog, misuse, abuse, alterations or vandalism. Thankfully, the corners of the front panel are rounded, unlike the less ergonomic SMSL D6 that I reviewed recently. Coming in at 139x32x147.5mm (WxHxD), the C200 takes up little real estate on the desktop. With a power output of 1.3Wx2, it should have enough muscle to drive all but the most demanding headphones. Thanks to a near 0 Ω output impedance from the headphone section, the C200 is ideal for sensitive all-BA IEMs too. In addition, the headphone output has 2 gain settings: Low-gain 0dB and High-gain 11dB giving you more precise control over the output. Design Non l ho collegato al pc ma per l uso che ne faccio io posso dire che è un apparecchio davvero azzeccato che mi permette il controllo del volume senza perdere di dinamica anche a basso ascolto e taratura personalizzate per l ambiente e le eventuali elettroniche associate. Ho tutti i controlli in flat e non manca proprio niente. I must admit I am a fan of all-in-one units and the SMSL C200 is currently one of my favourites in the entry-level segment. It just seems to work well with any IEMs or headphones I plug into it. I like the simplicity of it too and the build quality feels reassuring.Although it's so small, the SMSL C200 is able to drive practically any headphones out there. Even fairly demanding headphones such as the HiFiMAN HE-560 are driven easily and show no issues at all. Starting with the design, we have many features that are rather rare in the audiophile world, especially at this price range. C200 is an interesting product, because it has both features, you’d typically expect to see on an interface designed for recording, mixing and mastering, and because it has a price point you just don’t typically see in audiophile products.
