Violectric HPA V550 PRO Headphone Amplifier $2799 Review

June 10, 2021 § Leave a comment

 The balanced amplifier circuit is a variation of the 2009 design, although it is now compatible with lower impedance loads. The PRE-GAIN stage implemented in the Violectric headphone amplifiers ensures not only a low noise floor, but also precise control of output levels due to the ability to tailor the sensitivity of the pre-amplifier stage. The volume control is an impressive piece of engineering, as the ability to execute a 256-step volume control with .4 dB increments is nothing short of amazing. Finally, the HPA V550 PRO is a solidly designed preamplifier, and can function equally well in a traditional two channel audio system. If you are searching for a high-performance headphone amplifier then give the Violectric HPA VM550 PRO serious consideration, as there are very few products in the audio world that are built to this level of sophistication.
