Beskrivelse

Audiophonics is proud to present the HPA-INT450ET. This Class D integrated amplifier relies on a pair of Purifi 1ET6525SA amplifier modules coupled with a Hypex SMPS1200A400 power supply to deliver incredible performance. Like all Audiophonics Workshop products, this HPA-INT450ET is meticulously designed and hand-assembled in our workshop in France.

The Audiophonics HPA-INT450ET is a powerful, robust and high-performance amplification solution. It is capable of powering demanding HiFi audio systems, while revealing sound reproduction of incomparable finesse, rich in detail and perfectly transparent. There's no compromise here between power and sound accuracy. The on-board Purifi modules feature a particularly rigorous design, delivering exceptional measured performance.

All elements and components are integrated into a solid, sturdy aluminum housing with a sleek, modern design. This chassis also features openings and heat sinks on the sides to dissipate heat efficiently. What's more, its design effectively limits the impact of interference on the audio signal.

Audiophonics HPA-INT450ET: Purifi amplification modules

Each channel of the Audiophonics HPA-INT450ET amplifier circuit is equipped with its own Purifi 1ET6525SA amplifier module. These use high-performance Class D architecture, with available power of 2x450W into 4Ω or 2x230W into 8Ω (at 1% THD) and high efficiency of over 94%. They also guarantee a very low level of THD, intermodulation distortion and noise, for a rich, precise and perfectly transparent sound reproduction, perfectly respecting the original audio signal to reproduce your music with unequalled fidelity and without coloration. It also guarantees a wide, realistic sound image, for perfect immersion.

Purifi's ongoing research into non-linear control theory has led to the development of the first mathematically accurate large-signal model for self-oscillating amplifier controllers. This breakthrough enables the feedback circuit to be fully optimized, resulting in a significant performance improvement over other designs. Furthermore, these Purifi 1ET6525SA modules feature a complete protection system for enhanced durability.

Sjukt bra förstärkare i nyskick med fjärrkontroll, kvitto, garanti, nätkabel och originalkartong.

Har de nya Purifi 2 Chippen på 2 x 450W samt är oerhört strömstark, driver vad som helst och blir aldrig varm!

Bara ett år gammal, sparsamt använd pga har flera olika förstärkare som jag växlar mellan.

Likvärdig spec som NAD M33 V2 som kostar 75,000kr. M33 har dock inbyggd streamer och dac.

Nypris 21,000kr inkl svensk moms och frakt.
