Seller's Description

Overview
Description

The HPA V550 PRO covers most features of the review winner DHA V590 - except the D/A converter.

So, HPA V550 PRO covers the analogue functionality, the perfect driving of any dynamic headphone and the outstanding pre-amp function. The latest findings from the multiple test winners from Violectric and Niimbus were implemented in the headphone amplifier. All functions can be conveniently controlled using a stylish remote. With its incomparable technology, HPA V550 not only offers one of the most powerful headphone amplifiers in the market, but also:

Lowest Noise - through a very small amount of internal gain. This makes the amplifier's self-generated noise inaudible.

High Output Voltage - through 50 V internal operating voltage. Therefore ideally suited for high-impedance headphones deserving high output voltage swing.

High Output Power - thanks to powerful amplifiers that offer far more power even the most demanding headphones would need. So best suited for headphones with low impedances as well as magnetostatic headphones

High Damping Factor - due to lowest output impedance. Therefore the ideal match for difficult to drive headphones without negative side effects and with the guarantee for a uncompromising frequency response.

Remote:
Control the HPA V550 PRO with its stylish remote control, milled from a solid piece of aluminum. Via infrared rays you have access to motorized volume control, mute, input selection, resampling settings, Headphone and line-out control.

About Violectric

Violectric emerged in 2009 as a hi-fi sub-brand of Lake People, the esteemed German pro-audio manufacturer founded in 1986 near Lake Constance. Headed by chief engineer Fried Reim, who oversees development and production in Constance, Violectric adapts Lake People's robust professional circuitry for discerning home listeners, prioritizing engineering substance over hype.

The brand specializes in headphone amplifiers, such as the seminal V200 and newer models like the HPA V324, alongside high-quality DACs including the V800 and V850. Its lineup extends to phono stages like the PPA V630 and preamps such as the PPA V600, with the ultra-premium Niimbus series—exemplified by the US5—pushing boundaries in amplification. Absent are speakers, turntables, or cables; Violectric hones in on source-to-headphone electronics.

Positioned firmly in the high-end hi-fi market, Violectric commands respect among pragmatic audiophiles for its "tools, not toys" ethos—delivering uncompromised build quality, timeless design, and sonic precision at prices from around £700 to over £3,000. Free of esoteric claims, it appeals to buyers seeking pro-grade performance in elegant, enduring packages.
