What does that mean though? With \"unmusical\" DACs, think about the banding in the sky in low-res digital photos--the inability to smoothly run through subtle shades of the same hue. That's what happens in noisier, less optimized digital products; there's an inability to present the subtle shading that makes music human and real. All those little echoes, instrument decays, and minute resonances are buried under the noise floor of lesser DACs, and hence the use of \"digital' as a pejorative.\u003c\/p\u003e\n\u003cp\u003eBut \"digital\" isn't and shouldn't be a bad word. When done right, it has tremendous inner detail and life. High-resolution streams and recordings are commonplace, and these offer air and spaciousness just like good vinyl does.

That's what happens in noisier, less optimized digital products; there's an inability to present the subtle shading that makes music human and real.

Made in Italy.\u003c\/h3\u003e\n\u003cp\u003eThe InPol Legacy Integrated Amplifier is this Italian hi-fi genius' flagship product, incorporating all of its best innovations and breakthroughs learned over its 25-year history. The heart of the InPoL Legacy is Pathos' patented dual InPoL technology, in bridged configuration, combined with a tube stage.\u003c\/p\u003e\n\u003cp\u003eIt is named the Legacy because it represents the \"ideal legacy\" of Gaetano Zanini, co-founder, and owner of Pathos. With this amp, Pathos set itself the goal of making the best Pathos integrated amplifier ever, one that would match, if not surpass, the InPower and Adrenalin power amplifiers.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eSays Gaetano, \"In designing the new InPoL Legacy, we, therefore, set no limits on ourselves – primarily concerning weight and size, which we have previously tried to limit.\"\u003c\/p\u003e\n\u003cp\u003eThe result? A 308-lb, steamer-trunk-sized giant with a sound that is both big and soaring but also controlled and delicate.

InPol (short for Inseguitore Pompa Lineare, or Linear Pump Tracker) erases that compromise. It’s a patented, fully balanced, class-A topology where a single triode stage handles all voltage amplification—and maintains 100% of its sonic signature—while the InPol circuit delivers the current gain needed to drive even the most demanding speakers effortlessly.\u003c\/p\u003e\n\u003ch4\u003eFeatures of InPol\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003e1.

The two toroidal power transformers are the largest Pathos has ever made, keeping in mind the brief to set no limits on this design.\u003c\/p\u003e\n\u003cp\u003eThe power supply to the tube input stage is separate, with a toroidal transformer for each channel. The tubes are in a totem pull configuration, using two ECC803s TungSol tubes, and one 6H30 per channel.\u003c\/p\u003e\n\u003cp\u003eThe 100-step passive volume is adjusted by low-noise precision resistors using insulated relay switches.
