By housing a heavily shielded, custom-engineered linear power supply within its singular, low-profile chassis, the PW1 delivers a breathtakingly quiet noise floor and an expansive, effortless soundstage that honors the true artistry of vinyl playback.\u003c\/h2\u003e\n\u003cp\u003eFor many generations, true lovers of sound and music are inspired by vinyl playback. Even in these days of high performance digital audio playback systems it is hard to imagine a future without LP’s. There’s just something magical to it. \u003c\/p\u003e\n\u003cp\u003eGrimm Audio’s co-founder Peter van Willenswaard spent a life time designing and improving phono preamps, both in solid state and with tubes. Of all stages of audio amplification, phono preamplifiers pose the biggest challenges to a designer. With moving coil cartridges, deep bass signals of a mere 50 nV require no less than 90 dB amplification! \u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eFor the PW1, Peter managed to develop a solid state phono preamplifier that matches his best tube based designs. Peter believes that designing a good phono preamp is not about achieving the lowest possible harmonic distortion as an isolated parameter. He searches for an elegantly minimalistic circuit design in which he optimizes the ‘electric environment’ of all the active components, in conjunction with a meticulously tuned power supply. Needless to say that passive components like capacitors and resistors are carefully picked.\u003c\/p\u003e\n\u003cp\u003eThe result is a well balanced design with Peter’s signature sound, which is very spacious, detailed and open, but at the same time rhythmically addictive and emotionally involving.\u003c\/p\u003e\n\u003ch5\u003eFeatures\u003c\/h5\u003e\n\u003cul class=\"wp-block-list\"\u003e\n\u003cli\u003eUnique minimalistic electronic design\u003c\/li\u003e\n\u003cli\u003eMC and MM cartridge inputs\u003c\/li\u003e\n\u003cli\u003eRCA and XLR outputs\u003c\/li\u003e\n\u003cli\u003eGain and load settings under bottom plate\u003c\/li\u003e\n\u003cli\u003eInternal silent linear power supply\u003c\/li\u003e\n\u003cli\u003eCopper shielded interior\u003c\/li\u003e\n\u003cli\u003e100 x 100 x 250mm (WxHxD)\u003c\/li\u003e\n\u003cli\u003e5 year limited warranty\u003c\/li\u003e\n\u003cli\u003e\n\u003cmeta charset=\"utf-8\"\u003eMade in Netherlands \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"technical-description\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e \u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"technical-description\"\u003e\n\u003cmeta charset=\"utf-8\"\u003eGeneral:\u003c\/div\u003e\n\u003cdiv class=\"technical-description\"\u003e\n\u003cul\u003e\n\u003cli\u003eMax. ambient temperature for operation: 45 °C.\u003c\/li\u003e\n\u003cli\u003eInternally set line voltage 100\/115 V or 230 V.\u003c\/li\u003e\n\u003cli\u003eIEC C18 type line voltage connector (without safety earth pin).
