Every SoundImpress amplifier gets extensively tested and manually assembled at our headquarters in Groningen, the Netherlands. Our amplifiers are built to last. Therefore, SoundImpress amplifiers come with a standard 5-year warranty!

SoundImpress amplifiers contain components from European industry-leading manufacturers such as Purifi, ICEpower, and Hypex. For years, it was our goal to develop a product that truly fulfils the company's core motto – SoundImports: Helps the music sound the way it should.

In this blog, we would like to present to you our top 3 power amplifiers from SoundImpress.

SoundImpress PU400-2CH Stereo Amplifier | 400WPC | Eigentakt | Powered by Purifi

Let's start with the high-end class-D stereo amplifier, based on Purifi Audio's Eigentakt technology: the SoundImpress PU400-2CH stereo amplifier. This amp offers its users a powerful 425W per channel. Making this SoundImpress amplifier very capable and highly affordable.

• Powered by state-of-the-art Purifi Eigentakt technology  
• Up to 2 x 450 Watt at 2 ohm load
• Efficiency up to 94%, further reducing power consumption
• Unprecedentedly low distortion over frequency and power range
• Balanced analog inputs (XLR)
• Banana-plug speaker connectors
• High quality aluminum chassis to offer extra heat dissipation capacity
• Dimmable LED
• Assembled by hand in the Netherlands

Thanks to high precision parts such as op-amps, high voltage gate drivers and high current MOSFETs, this amplifier can power almost any speaker. Be it a single subwoofer or your sophisticated 3-way tower. Thanks to the efficiency a high loop gain can be obtained, creating an unparalleled performance.

The Eigentakt implementation from Purifi is one the best amplifier technologies available. This class-D technology meets high standards and gives super performance at any playback level, regardless of load. This results in a stable, dynamic and realistic sound image, of any music genre. This amplifier will squeeze (with a proper music source and proper pre-amplification) all the dynamics out of your music without distortion, and at any volume.

In addition to the two-channel configuration, we also offer a mono version of this amplifier: the SoundImpress PU400 Mono Amplifier | 1 x 400W | Eigentakt | Powered by Purifi. Perfect to use, for example, as an amplifier for your subwoofer or to drive your speakers separately.

SoundImpress HY122-2CH Stereo Amplifier | 125WPC | Ncore® | Powered by Hypex

The following amplifier we would like to highlight in this blog is the SoundImpress HY122-2CH stereo amplifier, powered by Hypex.
The SoundImpress HY122-2CH Stereo amplifier is a compact, high performance, two channel and no-nonsense class-D power amplifier. It incorporates the proven and renown Hypex Ncore® technology for nothing less than impressive performance!
The performance stands out with authoritative and tightly controlled low registers, high dynamics and crystal clear mid- and high-frequencies. The super-low noise level generates a completely black background to reveal the tiniest of details in every recording. 

• Ncore® technology inside
• Impressive performance despite load 
• Neutral and transparent reproduction
• Flat, fully load-independent frequency response
• Plenty of power combined with high efficiency
• Compact design
• XLR input, binding posts output
• Assembled by hand in the Netherlands

This amplifier can deliver all its power from as low as 2 ohm impedance combined with low idle loss, very low distortion and noise levels. Chief distinguishing features are flat frequency response irrespective of load impedance, nearly frequency independent distortion behaviour and very low radiated and conducted EMI. Tthis results in performances such as the max output power of 125 Wrms at 4 ohm per channel, a Signal-to-Noise Ratio (SNR) of 118 dB and astonishing distorting level of 0.0015%.

An amplifier is only as good as the power supply it contains. In this SoundImpress amplifier, the power supply and amplifier are located on one board. The switched-mode power supply (SMPS) providing the power for the amplifier is a compact, high power, highly efficient, regulated half bridge converter with synchronous rectification on the main output rails. These properties make this technology ideal for powering Class D audio amplifiers.

SoundImpress ICE700-4CH Quad Amplifier | 400WPC | Powered by ICEpower

The last amplifier we would like to present in this blog is the SoundImpress ICE 700-4CH quad amplifier, powered by ICEpower.
As sound sources have evolved from LP’s to CD’s to streaming audio, a high quality power amplifier remains a key ingredient to any good Hi-Fi stereo setup. No matter whether you need an amplifier for your small bookshelf speakers or tower speakers, this amplifier with ICEpower technology inside creates a fantastic high quality result. 
Its four channels make the SoundImpress ICE700-4CH the ideal amplifier for 4-zone applications in a mono system or 2 zones in a stereo system.

• ICEpower technology inside
• 4 x 400 watts at 4 ohms
• Neutral and transparent reproduction
• Flat, fully load-independent frequency response
• State-of-the-art, high efficiency amplification
• ErP and Energy Star compliant power supply
• XLR input, binding posts output
• Assembled by hand in the Netherlands

The SoundImpress ICE700-4CH is a audiophile, high performance class-D power amplifier. The performance stands out with high dynamics and crystal clear mid- and high-frequencies. All SoundImpress amplifiers are hand assembled in the Netherlands. The custom milled aluminum enclosure, which houses two ICEpower 700AS2 amplifier modules, is the best thermal material for audio devices. It can operate from both 110 and 230 VAC mains voltage due to it's universal mains input compatibility featuring an automatic input voltage doubler. 

This amplifier can deliver all its power from as low as 4 ohm impedance combined with low idle loss, very low distortion and noise levels. Chief distinguishing features are flat frequency response irrespective of load impedance, nearly frequency independent distortion behaviour and very low radiated and conducted EMI. This results in performances such as the max output power of 400 Wrms at 4 ohm per channel, a Signal-to-Noise Ratio (SNR) of 117 dB and astonishing distorting level of 0.005%.
