Xue Lin ihifi800 player is about to begin closed beta, will be invited to 10-20 senior User Experience, start date to be announced. ihifi800 is Xuelin upcoming blockbuster 192K music player, which uses more than 15 dollars ES9018k2m priced flagship decoder chip. To improve the performance of the circuit at the same time we conducted a number of innovations in such a petite size we still use the four distortion as low as 0.00002% of the top rail to rail op amp dual lme49726. Respectively, as the machine i / v, lpf, buffering. (Note: Previously published in this section is a passive program lpf, has been changed) power supply with the cost of a more expensive multi-channel servo voltage source, the more traditional LDO transient indicators of magnitude improvement. Filtering is a rare film Panasonic (Lapis) series. At the same time the important parts of the circuit board are added electromagnetic shielding treatment, so that the noise floor of the system to reach a very low degree.Adhering to carry our years of accumulated experience in manufacturing and tuning in the preliminary prototype evaluation, ihifi800 the sound at the end of darkness, the sound field broad, sweet, low-key and reserved, not tired a long time to listen, to reach a satisfactory level. With only good performance is not enough, the whole shell is extremely time-consuming use of all Buxigongben full cnc aluminum alloy, with excellent metallic finish. While its volume is only 100 * 49 * 15mm, weight is about 110g. excellent portability, to overturn the traditional brick clumsy country's image.
