QLS QA390 Mod BlankUpd: it comes with a beautiful carrying case for the player itself and accessories Right away about the main thing, about the sound: the best player became even better. DACs remained the same - two Asahi Kasei AK4497, the balanced circuitry is preserved, but the amplifying part and power supply have changed a lot. Many recognized that the original QA390 was too neutral, to the point of sterility. In QA390 Mod this is defeated, the player became more musical, while retaining all the main advantages: outstanding resolution, layering, volume, separation of instruments, air, stereo effect. Noise with sensitive in-channels like the Samrfir? seemed to me to have been defeated as well. The player has the highest output power, pumps almost any full-size headphones, not to mention in-channel ones. There are several modes of amplification (power / current), I recommend selecting for each headphone for better synergy. It is possible to use QA390 Mod as a USV DAC and as a digital source. The player plays DSD and other Hi-Res formats (see the full list in the specifications). There is an excellent IPS screen, convenient control. The device has a built-in slot for full-size SDHC memory cards (single-chip single-threaded SD card player for maximum sound quality). From experience, Sandisk cards are recommendedMy QA390 Mod has a stylish-looking black aluminum case with a gold sound controller. In terms of visual differences of the Mod version from the usual QA390 there are factory made model names on the screen frame and on the back side of the device. Realized work on Bluetooth 5.0 as a receiver, while supporting modern technology for the transmission of high-resolution audio HWA (LNDC) from Nuawei. The Mod works well with the headphones Vey?rdyn?mi? T5p-2 (AK version), S?nhe???r ND800S, K?npert?n V?li, Snorr? TDS-5 Mod, intra-channel S?nhe???r IE900, Noble Soultan Damas?us (fantastic bundle), AAW Nightingale (rare player can pump them normally), Nifiman R?2000 ?r? and ??tell & Kern T9I?. Top-sound for the money! The condition of the player is NEW, used extremely carefully. Sell for the reason of trying to accumulate on Visions Ears Aura
