There are multiple independently tracking power supplies, superior internal shielding and higher output power. Finally the Eclipse amplifier offers a new, modern, ‘lighter’ take on the distinctive and award winning Halcro aesthetic. Even this contributes to better performance with the new, machined-from-solid casework reducing microphonics.\u003c\/p\u003e\n\u003cp\u003eHalcro amplifiers offer an unmatched insight into the music. They position everything precisely in the soundstage due to their unique ability to avoid adding ‘ghost’ notes that are thrown into the mix by the non-linear distortion of a conventional amplifier. Lack of distortion aside, one of the many things that make Halcro amplifiers so good is the way they maintain the phase coherence of the signal source. Phase coherence is a measure of the degree to which a system maintains the relative timing of various notes or tones within complex music.\u003c\/p\u003e\n\u003cp\u003eWhen it comes to driving your loudspeakers musically, the Eclipse has no peer. The Eclipse mono produces 300 watts\/per channel into an eight-ohm loudspeaker, 550 watts\/channel into four-ohms with a peak power of 2.1kW for the most dynamic of transients.\u003c\/p\u003e\n\u003cp\u003eBeyond all the technology, there is only one thing that matters: the ability to convey the emotion of music!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVideos\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eZero-Distortion Amplification: Halcro Out of Hiatus – SoundStage!

Its sound quality is so breathtakingly good that I had to pinch myself through my listening sessions to remind myself I was awake, and not in some blissful audiophile dream. They’re certainly not cheap – though recent changes in Halcro’s distribution model and a streamlined paint process have reduced them from the launch price of AU$135,000 a pair to now a US dollar price of $69,990 a pair (around AU$91,000 as we write). But to describe the performance of the Halcro Eclipse Monos, I can do no better than echo the praise of Stereophile’s Paul Bolin, who in turn paraphrased Shakespeare to say: “Feed them the best, and the Halcros will give you an experience that is such stuff as dreams are made on”.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/halcro.com\/wp-content\/uploads\/2019\/09\/Halcro-Eclipse-Audio-Esoterica-Review-compressed-1.pdf\"\u003eRead Review\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures \/ Tech Specs\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePower output into 4 ohms resistive \u0026gt; 500 W\u003c\/li\u003e\n\u003cli\u003ePower output into 8 ohms resistive \u0026gt; 280 W\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e(Measured at 1kHz)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDistortion (Footnote 1)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAt full power output, all harmonic distortion orders:\u003c\/li\u003e\n\u003cli\u003eTHD \u0026lt;-120 dB (\u0026lt;300 parts per billion) up to 20 kHz (100 kHz B.W.) at 450 W into 4 ohms.\u003c\/li\u003e\n\u003cli\u003eTHD @ 1 kHz \u0026lt;-134 dB (\u0026lt;200 parts per billion).\u003c\/li\u003e\n\u003cli\u003eFor sum of 19 and 20 kHz tones, each delivering 112.5 W into 4 ohms = peak power 450W, resulting intermodulation products each \u0026lt;-120 dB relative to output.\u003c\/li\u003e\n\u003cli\u003eSMPTE-IM intermodulation products each\n\u003cp\u003e\u0026lt;-120 dB relative to output.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eInputs\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThere are four input modes:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ean unbalanced voltage mode input with an impedance of 22 kOhms\u003c\/li\u003e\n\u003cli\u003ea balanced voltage mode input with an impedance of 22 kOhms + 22 kOhms\u003c\/li\u003e\n\u003cli\u003ea current-mode input with a 60 Ohm input impedance (infinite impedance current source)\u003c\/li\u003e\n\u003cli\u003ea minimal path voltage mode with an input impedance of 660 Ohms\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe voltage gain of the balanced and unbalanced inputs is 30 V\/V and for the minimal path mode is 15 V\/V.
