Welcome to Queenway Store!
1.Some items parameters produce from AliExpress system, some of them aren't correct, even fully wrong, the detailed description of products should be correct for us.
2.110V and 220V, If you are in 110V area, please tell us.
3.International shipping/transportation cost, it is 2~10 dollars/Kg, many items of our store are very heavy or big volume, it is 65Kg~500Kg, or 0.5~3.0m 3
, the plane shipping fee will be too expensive, the sea shipping is the cheapest and trade safe, but it has no tracking numberm, and need more time(35~70 days)on the process, we must talk about some details deeply if using sea shipping.
4. Some items price wave often, but we try to give the best price to you, because the international shipping is high, we must use a low product price to balance the international shipping fee.

Features:
Good sound comes from good electronic components
The pre-stage tube adopts the American RCA metal encapsulation tube 6SH7 in the 1940s; the Swedish original customized Lundahl headphone amplifier special output; the British original custom-made power transformer; the coupling capacitor uses the German Mundolfo silver foil oil-immersed capacitor; The fever level Jinwei resistor is used; the signal switching switch and the volume control encoder are all made of ALPS fever products.
ES9038pro decoder chip
Adopt ESS company decoder chip ES9038PRO, ultra low distortion, high signal to noise ratio, large output current. The system clock uses an ultra-low phase jitter US Sitime active quartz crystal with a phase jitter of less than 0.5px. Regardless of the format of the LD-A1, the sampling frequency is high, which ensures smooth and phase-locked decoding.
2A3 ultra low distortion amp
LD-A1 with American RCA antique tube 6SH7 + Svallock JJ 2A3 single-ended pure class A ultra-low distortion headphone amplifier, the output power reaches 5W rms, the overall sound field, positioning, air feeling is unforgettable.
The LD-A1's full-range analysis is excellent, and it is modern, pursuing analytical and dynamic styles. Transient response is especially good, listening to any music will give a refreshing and transparent feeling.
The LD-A1 adopts the design of the power supply cow and the host split. The channels do not interfere with each other. The balance sensor and the extremely sensitive headphones can not hear the noise.
