Best Combined Headphone Amplifiers and DACs

FiiO E07K Amp & USB DAC 

Virtually all PCs and laptops have the wherewithal to put out an analogue audio signal, but the quality is often less than perfect. These components are selected to do the job, rather than knock everyone’s socks off with sound quality.

However, there are options other than buying a new PCI card or cracking your laptop open; why not try an external DAC?

The E07K is the ideal starting point for those who want good sound for few pounds – just connect to the USB port and select the correct input on the device. Your PC/Mac should spot it and install automatically.

Added to that, the E07K can come with you and become a headphone amp for your phone or player, helping to drive your headphones for an even better sound on the move.

Added to that, the E07K can dock in the Fiio E09K desktop amplifier, to provide a stylish and powerful means of powering the thirstiest headphones.

Hifiheadphones verdict :

The E07K may be the lowest-cost unit in this list, but do not be fooled – this may represent the most significant upgrade anyone can achieve for this price.

FiiO E17 Amp & USB DAC

The E17 is very similar to the E07K at first glance, and is exactly the same size and shape; it fits also into the Fiio E09K desktop amp for more power.

The sound is slightly warmer that that of the E07K, and the E17 boasts additional inputs such as coaxial and optical.

Gives great sound and functionality; use with your computer as a DAC, then take it with you as a portable headphone amp!

Hifiheadphones verdict :

Like the E07K, the E17 represents amazing value for the music fan on the move.

The form factor of the E18 means that any typical android device can be strapped to it with no great departure from the original size/shape, so it’s perfect for slipping into a pocket so you can concentrate on enjoying your music.

Added to that, you needn’t worry about your phone’s battery again since the E18 can provide power for that too – in short, the perfect low-cost companion for those longer journeys.

Beyerdynamic A 200 p Amp & DAC for Apple devices

Developed in partnership Astell and Kern, there is no doubt about the quality of this unit, like the pedigree of the makers. The A 200 p makes for an improved punchier bass end with smoother, more dynamic sound when compared to a typical smartphone DAC only.

Now a 30-pin connector is available for the iPhone 4, so don’t upgrade your phone – just upgrade your sound!

Hifiheadphones verdict :

For its price, the Beyerdynamic A 200 p represents great value and can compete with much higher-priced DACs which can accept data from Apple devices.

Cypher Labs Theorem 720

Cypher Labs’ products are well known for their functionality with Apple devices; they have enjoyed great success with their Algorhythm Solo –R and Solo –dB dacs, and also their Duet portable amp.

Now both amp and DAC is within the same case, for greater portability and convenience for an amazing sound wherever you are.

3 gain settings ensure a good level for all headphones and earphones, and an output impedance of less than 1 Ohm will suit earphones of 8ohms or more – so will suit practically any headphone you care to throw at it.

The sleek case offers a glimpse at the internal components, illuminated by a cool blue LED when in use.

The balanced HD800 cable CH800 S is available for use with both the HDVD800 and its amp-only sibling, the HDVA600.
