Best Kguss in 2026

👍 Up to DSD256 and PCM384 ▶️ TOPPING D10s USB DAC is compatible with 16-32bit/44.1-384kHz and DSD64 - DSD256(support both Dop and Native) If you need a DSD configuration guide, please contact the seller HIFI COLLEGE.

👍 XMOS XU208 and Customized Driver ▶️ TOPPPING D10s DAC use XMOS XU208 for USB interface and use customized driver which from Thesycon for better compatibility with high resolution audio file especially DSD native.And use ESS ES9038Q2M to make THD+N as low as 0.0002%@1kHz

👍 Automatic Power On/Off ▶️ Although the USB port support power after PC has shutdown,D10s still will synchronously power on/off with PC

👍 Ultra-High Performance NFCA modules ▶️ L70 uses the same NFCA (Nested Feedback Composite Amplifier) module with A90. Voltage current hybrid feedback architecture along with UHGF (UItra High Gain Feedback) technology provide excellent DC and AC performance, ultra-low THD+N and absurdly high dynamic range of 146dB.

👍 Fully balanced ▶️ The L70 is compatible with common headphone jacks including: 4-pin XLR balanced, 4.4mm balanced, 6.35mm single-ended, and 3.5mm single-ended. The built-in fully balanced amplifier circuit can not only fit well with balanced headphones, but also have perfect performance with single-ended headphones.

👍 Compatible with almost all kinds of headphones ▶️ TOPPING designed the L70 to be able to power the vast majority of headphones. With high output voltage, it easily drives high impedance headphones. With high output current, it easily drives low impedance headphones. And with low output noise, it easily powers highly sensitive IEMs without creating background hiss.

👍 Fully Isolated Design ▶️ The HS02 has a fully isolated design, which does not introduce new interference when the auxiliary power supply is used while the audio signal is isolated from ground loop interference. Say goodbye to the ground loop and hum.

👍 Switching between two interfaces ▶️ The HS02 has two input interfaces (including a USB-B and a Type-C) and two output interfaces (including a USB-A and a Type-C), either of which can be selected by an input switch or an output switch. Note: Input is used to connect to the computer, output is used to connect to USB devices.

👍 High speed is also highly compatible ▶️ HS02 supports automatic identification of USB2.0 transmission at low speed, full speed, and high speed. The powerful transmission capability is compatible with high resolution audio such as PCM32bit/768kHz and DSD512 Native.

► TOPPING Pre90 Preamplifier ► Pre90 adopts full balanced structure, which can handle balanced and single-ended signal processing. The output can be balanced, sin-gle-ended, balanced + single-ended. With the balanced + single-ended two-way input, in addition to the normal preamplifier usetage, Pre90 can be used for "balanced to sin-gle-ended"or "single-ended to balanced"signal conversion.

► Selectable XLR / RCA output ► The output of Pre90 could be config to “XLR only”, "RCA only" or "XLR + RCA ". Therefore, the amplified signal can be connected to two different amplifiers. Good combination with EXT90 D90.

► Ultra-high Performance NFCA modules ► Pre90 uses the similar NFCA ( Nested Feedback Composite Amplifier )module from flagship A90 Voltage Current hybrid feedback architecturelong with UHGF ( Ultra High Gain Feedback ) technology provides excellent DC and AC performance. Ultra-low noise of 0.3uv is milesahead of the competition, giving an absurdly high dynamic range of 145db and no audible noise and darkest background.

►4-Pin-XLR+4.4mm 6.35mm output► Since then, buying headphones does not have to consider whether the plug matches the headphone amplifier,because the A30Pro already provides you all in a compact body,including 4-PIN XLR,4.4mm,6.35mm.

►SE+BAL input pass through► When shutting down, the input signal is directly output to RCA or TRS without amplification, which will be more suitable for active speakers/monitor speakers when the DAC has pre-amplifier functions. Even better is when used with D30Pro, the excellent noise performance of D30Pro is not wasted.

►Say good bye to the ground loops noise► When multiple equipment are used, RCA connection may encounter ground loop noise A30Pro introduces a GND/LIFT switch as the solution. When in normal use,set it to GND; when encountering ground loop noise,switch to LIFT to change the ground point of the A30Pro from the it's chassis to other equipment which it connected to.Ground loop noise disappeared."
