SPL Phonitor xe

Audiophile stationary headphone amplifier with Voltair technology

5 / 5

The flagship model among the SPL's headphone amplifiers is the Phonitor xe. In contrast to the similarly priced Phonitor x, which with its balanced output can also be used as a preamplifier for a power amplifier and loudspeakers, the Phonitor xe is a pure headphone amplifier for the most demanding applications. You can choose between a version with or without an integrated D/A converter, which has been further improved compared to the other models in the Phonitor series.

Audiophile, stationary headphone amplifier with XLR outputs

4.6 / 5

Naturally, the corresponding headphone amplifier is not missing from the range of products offered by the Lower Saxony-based manufacturer: The HDV 820 is housed in a stylish, flat, black anodised casing with an internal power supply unit and so visually it is a matching partner to the HD 800 S.

4.3 / 5

Cambridge Audio have been active in the field of high-end hi-fi technology for five decades.

SPL Phonitor One

SPL Phonitor One

Headphone amplifier with crossfeed function

4.8 / 5

For smartphones and inexpensive stationary audio devices, but also in the studio, one should refrain from making overly high demands on integrated headphone amplifiers. They are part of an overall cost calculation for the product and often, in a sense, more of an accessory than a selling point. Accordingly, a dedicated headphone amplifier can certainly improve your listening experience, since it is a piece of technology that devotes its full attention to precisely this task. This is the case with the Phonitor One from SPL.
