The topaz is an impressive DAC/Amp that has been a pleasure to explore. If you’re in the market for an excellent transportable solution that drives any headphones under the sun, you have to give the WA11 serious consideration. If you can, go to your closest dealer and try it for yourself and let it convince you.

Violectric Chronos is the best USB dongle I’ve ever listened to. As the first-ever portable product from Violectric, this is quite a success. The Chronos has excellent build quality, simple operation, and a minimalistic design with elegance.

Here, there was plenty of power and no hint of strain from the amplifier. Tonal response remained constant up to max volume which was quite loud. But not loud enough to make the cups flap in the wind. If you are looking for a tiny device to drive your full-size headphones, I don’t know whether there’s a cheaper option than the E10K TC.

I assume that everyone of you already have a smartphone – you may even be reading that review with one – which mean that you have a very potent source in your hand. Give this source the gift of a (short) lifetime, and pair a FiiO Q7 with it/him/her, it’ll be worth every penny. The WA11 is one of the rare portable products that really knows how to handle the more complex to drive cans. It brings a performance to the table that’s in the class of desktop gear. Headphones like the Diana Phi or Empyrean I enjoy most when driven by the WA11. It just makes them sound stunning. It is impressive what kind of quality Woo Audio has achieved with the WA11. The Violectric DHA V590 is a strong all-around performer. In the beginning, I wasn’t too impressed with the internal DAC, but the more I used the unit, the more I used it as a DAC/AMP combo. They’re just made and tuned for each other. Headphone wise the HDA V590 is a great all-around performer as well. No matter the driver technology used in the headphone, the V590 will sound really good to great with at least 90% of the headphones you hook up to it. My absolute favorite being the Audeze LCD-XC. On my initial impressions I did not find any sound quality difference from K5 pro. Will update if I find any,.The iFi Micro iDSD Signature is surely a special unit. It is an excellent performer with a premium build, design, and internal components. It’s also very versatile with outputs and features. If you need something more out of a DAC/Amp then I don’t know what else would fulfill that. When it comes to sound, iFi always delivers and the Signature is no exception. What? No iFi Micro iDSD BL? Surely, it is in the same ballpark as the Mojo. Maybe, you have not reviewed it yet. From what I have read, it is a virtual “Swiss Army Knife”, of AMP/DACs ( portable or at least transportable). Also, it is said to be at the same level of sound quality as the Chord Mojo. The yellow LED as with the Topping D10 adds a much needed touch of color and uniqueness to the unit. The volume knob adds more to that sauce, making for a small box and you enjoy glancing at on your desk. The TOPPING DX3 Pro+ DAC/Amp is TOPPING’s upgrade of their classic DX3 Pro. With a new Bluetooth chip and DAC chip, the Pro+ outperforms its predecessor while also coming in at a lower price point. The Pro+ has 60% lower THD+N (DAC), 85% lower THD+N (HPA), over 100% more power, and 90% lower output impedance than the DX3 Pro (LDAC version). The market of compact DAC/AMP modules is getting stronger and better each month. ddHifi with all of their units, and especially this TC44B, prove they are one of the most important players when it comes to high price/performance ratios in miniature-sized portable units.
