It has solidity, dimensionality, vitality, transparency, excellent transient response, well-defined and extended bass, a superbly rich midrange, and very low noise. A sensibly wide range of loading options is available for MC's, which are stepped up by transformers, which must be in part responsible for the deliciously smooth, unfatiguing highs.

The new ESP Supply unlocks the true potential of the circuit, so it is at ease and doesn’t have to work as hard. It allows more music to flow through with more detail. It also creates a more dynamic presentation, the quiet passages are quieter and louder passages have more punch. The sound quality is an improvement throughout the frequency spectrum, so you have better clarity on the bass, midrange, and highs.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eHere are the top 8 improvements:\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eThe transformer changes from an IE to a Toroid design, which generates significantly less noise because it does a better job of concentrating the magnetic field\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eThe high voltage increases by 17% from 250 V to 300 V which provides more headroom\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eDynamic range is increased from 2 dBV to 11 dBV, so the quietest parts are quieter and the louder parts are louder\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eThe ESP Supply is designed with bigger, fewer and heftier parts, which delivers more power with improved reliability\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eThe rugged design of the ESP Supply makes it more resilient to power surges.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eBoth the high and low voltage supplies provide more current, so it’s less restrictive to deliver more music\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eMaximum output level before clipping is increased up to 3 V RMS, depending on the unit to allow more punch\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eIn the Phonostages, the noise level is 5 dBV quieter, which increases the black levels considerably\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch4\u003eWhy a Phonostage is So Important\u003c\/h4\u003e\n\u003cp\u003eWhen a vinyl record is made the volume of the bass is reduced and the treble is increased. Otherwise, the bass would cut a groove too big for a stylus to read or for the music to fit the record. The phonostage reverses the process by taking the delicate signal from your cartridge and adjusting it so that the bass and treble are restored to their original volume. This common standard is known as the RIAA curve.\u003c\/p\u003e\n\u003ch4\u003eThe Andros\u003c\/h4\u003e\n\u003cp\u003eInspired by RCA’s vacuum tube circuit designs from the 1930s, the Andros has been engineered to bring you the clarity and depth of the original recording.
