Desktop DAC/AMPs - Wish Audio

Balanced. Budget. The FiiO K9 Desktop DAC/Amp is a mid-fi heavyweight. From the DAC to the amplification to the volume adjustment, every part of the K9 is truly balanced for greatly reduced crosstalk and distortion. Featuring Bluetooth 5.1, dual THX chips, and dual ESS DAC chips, it provides everything you need to enjoy extremely high-res sound files like LDAC, 32-bit/768kHz PCM, and DSD512. Dual DAC chips for truly balanced decoding Two ES9068AS DAC chips decode the left and right channels separately, providing a truly balanced experience. These 32-bit chips use ESS’ Hyperstream II architecture boasting high dynamic range and extremely low distortion.  High-end THX amplifier for linear sound The signal is passed from the DAC chips to the dual THX AAA 788+ amplifier chips, which provide an extraordinary 780mW of output power at 300Ω and up to 2000mW of output power at 32Ω. Known for their low distortion, these amplifier chips serve up a clean and linear sound profile. Bluetooth 5.1  Enjoy the latest hi-fi Bluetooth codecs like LDAC and aptX HD thanks to the K9’s Bluetooth 5.1 chip. Faster and more stable than previous BT versions, Bluetooth 5.1 is even better at providing latency-free hi-def playback. Partitioned design maximizes performance The PCB of the K9 features a partitioned layout, fully separating the major sections of the audio circuit: the power supply, signals, and analog signal loop. This guarantees lower distortion and crosstalk for an altogether cleaner output signal. Isolated digital and analog section power supply In addition to the partitioned PCB, the power supplies are also isolated, delivering power to the analog and digital portions separately to further reduce interference. Dual-mode clock management Accurate and stable dual-mode clock management allows the K9 to easily play back even 32-bit/768kHz high-resolution audio with incredible fidelity. 120-step volume potentiometer The dampened volume knob is powered by ADC curve reconstruction that allows you to precisely and smoothly adjust between 120 levels of volume, with minimal noise and volume deviation between left and right channels.

TOPPING DX9DAC AK4499EQ Headphone Amplifier NFCA Bluetooth 5.1 AptX LDAC 32bit 768kHz DSD512 BlackTOPPING DX9 DAC AK4499EQ Headphone Amplifier NFCA Bluetooth 5.1 AptX LDAC 32bit 768kHz DSD512 BlackTo celebrate its 15th anniversary, Topping unveils a high-performance DAC / Headphone Amplifier: the DX9. In addition to its very high performance, Topping has given it a meticulous aesthetic with an innovative and unique design. The DX9 incorporates top-quality components, including an AKM AK4499EQ DAC chip. This DAC chip delivers performance equivalent to the integration of no less than two AK4499EXs. In fact, it enables the Topping DX9 to achieve a dynamic range of 131dB and a THD+N of less than 0.0007%. An AK4118AEQ chip handles the reception of optical/SPDIF signals, for very low jitter. On the headphone amplifier side, the DX9 incorporates a discrete NFCA amplifier circuit with 6 modules each comprising 39 transistors. The power supply stage is separate for the DAC and headphone amplifier parts, producing a pure, stable power supply. In terms of aesthetics, the curved case and the two screens with Topping's own Aurora UI interface provide the best possible user experience. In addition, a transparent top plate engraved with Topping's 15-year anniversary logo gives a view of the DX9's perfect circuit design.A high-performance chipsetTopping has integrated the rare and legendary AK4499EQ 4-channel DAC chip into the DX9. This chip alone achieves the performance equivalent of two AK4499EX chips, with a THD+N of less than 0.00007% and a dynamic range of 131dB. It enables the DX9 to support sampling rates up to PCM 32bit 768kHz and native DSD up to DSD512.The AK4499EQ DAC chip is coupled to an AK4118AEQ optical/SPDIF signal reception chip for perfect signal reception on coaxial SPDIF, Toslink optical and AES/EBU inputs. Finally, a CPLD works on the clock signal and digital signal optimization to obtain a perfect level of stability and purity.
