It keeps the original's heart - a precision R2R ladder with every resistor individually selected to 0.05% tolerance - and rebuilds everything around it, with seven confirmed upgrades including a discrete Class-A output buffer that drives XLR and RCA simultaneously. Selectable NOS, OS and hardware SRC modes, a direct 10MHz master clock input, full galvanic isolation and a new colour display complete a design housed in a unibody chassis CNC-machined from a solid block of aluminium.\u003c\/p\u003e\u003ch3\u003eThe Hi-Fi Centre Team Take\u003c\/h3\u003e\u003cp\u003eThe Harmony DAC 2 delivers the organic, natural sound that drew so many listeners to the original, now with an even quieter background and greater composure. Music has a full tonal body, rich harmonic texture and a long, relaxed decay, with the resolution and timing to keep complex recordings clear and engaging. Three PCM conversion modes let you tailor the presentation to your recordings and system, while full galvanic isolation keeps USB and source noise away from the conversion stage. With a 12V trigger, concurrent balanced and single-ended outputs and a direct master clock input, it is a superb, future-proof heart for a serious digital system.\u003c\/p\u003e\u003ch3\u003eKey Acoustic \u0026amp;

LAiV has also announced an upgrade kit to bring existing Harmony DACs up to DAC 2 specification.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eShould I use NOS, OS or SRC mode?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIt depends on your recordings, your system and your personal taste. NOS offers the most direct, purist signal path, LAiV's in-house OS mode provides a more refined, filtered presentation, and the hardware SRC converts PCM to 705.6 or 768kHz before the ladder. These modes apply to PCM only, as DSD is converted to multi-bit for the R2R ladder. Our team is happy to demonstrate the differences in our showroom.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need a DDC to use an external master clock?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eNo. Unlike the original Harmony DAC, which required a DDC feeding I2S for external clocking, the Harmony DAC 2 accepts a 10MHz master clock directly through its 50 ohm BNC input. Without a master clock, its internal Crystek femto clock delivers excellent timing on its own.\u003c\/p\u003e","brand":"LAiV","offers":[{"title":"Black","offer_id":67901659316277,"sku":"Harmony DAC 2-Black","price":5990.0,"currency_code":"CAD","in_stock":true},{"title":"Silver","offer_id":67901659349045,"sku":"Harmony DAC 2-Silver","price":5990.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2246\/9355\/files\/Harmony_DAC2_Black.jpg?v=1793814091","url":"https:\/\/hificentre.com\/products\/laiv-harmony-dac-2-r2r-dac","provider":"Hi-Fi Centre","version":"1.0","type":"link"}
