Photos of two versions First version Second versionSecond-generation S2 panda amp upgrade to the first version1) Upgrade split power supply design, the whole power section and the main amplifiersection completely out of the signal-to-noise ratio is more useful2) Main transformer core upgraded to A-level 0.23MM silicon senior audio specialtransformer, for twice the price of the R-type transformers3) Increased all the way to the source selection, single-chip control delay start andperfect headphone protection circuit4)The original designer for the components to teach sound, mass-produced in strictaccordance with the teaching acoustic components withS2 target headphones and sound:S2 outstanding with the goal of headphones: Sennheiser HD600.HD650. Philips SHP9000AKG K701 k601 k501 .S2 sound is described as: S1 for a outstanding performance in thethree-terminal high-quality headphones, the overall three-terminal balance, with the CPIcharacteristics separation circuit so the whole sense of low volume and intensity of the full,warm mellow IF, S2 at high frequencies on the special advantage of the entire high-frequencystructured,Beats By Dre, rigorous, and at the same time in the extremely high frequency did not split,Monster Beats by dre Pro,the details of the sound, a stretch and bright high-frequency control good! Comprehensivecost-effective amp models sound performance1)Group A amplifier circuit, with two driven the final stage than traditional amplifierquiescent current of three times (remember that than yo), which is the importantfoundation of the excellent performance of the sound of the amp and amp2) field on the tube as the input stage, so that the machine has a high inputimpedance and excellent high frequency performance.3) Core potentiometer Japan

ALPS high level of 27 potential, clear positioningand left-right balance4) resistance accuracy up to 0.5% and
