{"product_id":"kecesephonoplus","title":"KECES Ephono+ Phono Preamp with Power Supply","description":"\u003cp\u003eThe KECES Ephono+ is a phono preamp with an outboard linear power supply – for MM and MC cartridges and even for optical systems (DS Audio). Two separate enclosures keep the sensitive amplification away from the power supply.\u003c\/p\u003e\n\u003cp\u003eThe strict separation of power supply and audio circuitry is the whole point here: a cartridge's signal is tiny and reacts sensitively to interference. Supplied as a preamp plus separate power supply with connecting cable.\u003c\/p\u003e\n\u003ch2\u003eWhy the KECES Ephono+?\u003c\/h2\u003e\n\u003cp\u003eBecause separate enclosures minimise interference. The external power supply works internally at ±24 V via a KECES H-Sonic toroidal transformer. Gain and impedance are finely adjustable, a switchable subsonic filter removes the lowest interference frequencies from warped records, and connections are available both balanced (XLR) and unbalanced (RCA).\u003c\/p\u003e\n\u003ch2\u003eWhat you hear\u003c\/h2\u003e\n\u003cp\u003eA lot of calm around the music: thanks to the low-noise power supply, even the high MC gain stays clean, and the subsonic filter makes the bass punchier by removing inaudible interference energy from the chain.\u003c\/p\u003e\n\u003ch3\u003eWho is the Ephono+ suited for – and who isn't it for?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003ePlain talk:\u003c\/strong\u003e the Ephono+ needs room for two enclosures – if you want a compact solution to tuck away, this isn't it. In return, Optical support (DS Audio) is rare in this price class. A precision tool for anyone who wants to listen deep into the groove.\u003c\/p\u003e\n\u003ch3\u003eCan I connect optical cartridges (DS Audio)?\u003c\/h3\u003e\n\u003cp\u003eYes, the Ephono+ offers its own gain stages (24\/30 dB) for optical systems – and supplies the power they need at the same time.\u003c\/p\u003e\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eA versatile, very quiet phono preamp with the rare Optical option – ideal for demanding MC and DS Audio systems.
