We hope it could bring you more fun at enjoying music. Input range USB IN PCM 44.1kHz-768kHz/16bit-32bit DSD DSD64-DSD512(Native) DSD(DoP) DSD64-DSD256 COAX/OPT IN PCM 44.1kHz-192kHz/16bit-24bit Specifications E30 II DAC parameters (LineOut/USB In96kHz) THD+N @1kHz (A-wt): ???? Supports high-resolution audio ?? TOPPING E30 II uses sub-flagship AK4493S chips of AKMs VELVET Sound technology. AK4493S is an upgraded version of the previous AK4493. AK4493S in parallel can achieve better performance and reduction ability than a single chip. ???? Coaxial and Optical also has good performance ?? The optical and coaxial input of E30 II supports up to 24bit192kHz audio, which is suitable for digital turntables, disk players, set-top boxes, and game consoles, so that traditional equipment can also give a new sound. The Digital Processing module provides better compatibility than the E30. ???? 5V power supply,anytime and anywhere ?? E30 II uses DC5V for power supply, which can easily access almost everywhere. You can power it up by USB port of PC, mobile charger or even a power bank. The built-in protection circuit will protect the E30 II and prompt on the screen after connecting to the wrong power supply. ???? Discrete LNRD ?? How to solve the noise problem of 5V power supply? The E30 IIs answer is the Discrete LNRD circuit (low noise reference driver). The Discrete LNRD circuit filters out the noise of various 5V power input and provides stable power supply of ultra-low noise reference level for E30 II. With this technology, the noise floor of E30 II is lower than 1 .5uV. ???? Pure DAC & DAC+Preamp application ?? E30 II is able to fix to maxmum output level so that it can be worked as a pure DAC. E30 II has built-in volume control function that can adjust the volume from -99dB to 0dB by using the remote control, so you are able to directly connect E30 II to power amplifier or active speakers, and control the volume of E30 II through remote control.

Topping L30 HiFi Headphone Amplifier / Preamplifier (Black). Sounds amazing but I dont need a headphone amp any more so I am selling.

TOPPING Pre90 Preamplifier. It is only a few weeks old and relatively unused. I used it to front my Keces S300 (Power amp - now for sale) and it was truly fantastic! Reviews state that this is a world class Pre-amp and that it slightly enhances the treble, but this sounded utterly perfect to me and im treble sensitive. My only reason for selling is due to chasing a valve amp for my headphones. I have sold my 2 channel setup. Buy with confidence, perfect condition and comes with all boxes. If you would like to discuss this product or anything else i have for sale, then call on 0797 3843815, Jon.
