Topping A90 balanced amplifier and D90 original AK4499 DAC in excellent condition, works perfectly and sounds amazing. Includes everything in photos. Please send a note with any questions for a prompt reply. Also includes a pair of studio quality 1.5ft balanced XLR cables. This is the rare original AK4495 before the factory fire. The main difference is the filters really do change the sound, vocals, acoustic instruments, and piano sound lifelike and rich. The amplifier has .1db channel balance up to 16 percent volume where they match perfectly (5 times better than Topping specification). Please send a note with any questions for a prompt reply.

For outputs, it has a single-ended RCA Stereo and a balanced XLR, which can be used one at a time or together simultaneously. The USB and IIS inputs support up to PCM32bit / 768 kHz and DSD512 Native. Optical, coaxial, and AES inputs support up to PCM24bit / 192 kHz. Finally, Bluetooth 5.0 input supports up to PCM24bit / 96 kHz LDAC.It comes with a volume control function so it can be used both as a DAC and as a DAC/Pre-Amplifier. This volume control can be disabled to make the D90 function purely as a DAC that produces output levels of 4Vrms (XLR) and 2Vrms (RCA).Review:I was quite stunned to find that D90 has such a clean and detailed performance, from the lowest bass to the highest treble, everything was there in spades and nothing would hide away from it. - Sandu Vitalie from Soundnews.Specs: Inputs USB-B (XMOS)IIS LVDS (HDMI)OpticalCoaxial SPDIFAES/EBUMQA (for MQA Version only) Outputs Balanced XLR Single Ended RCA D/A Chip: AKM AK4499 USB Interface: XMOS XU208 SPDIF Interface: AK4118 Bluetooth: aptX HD, LDAC, 5.0 Sampling Rates USB: PCM up to 32bit 768kHz / Native DSD up to DSD512 / DSD DoP up to DSD256 IIS : PCM up to 32bit 768kHz / DSD up to DSD512 Coaxial, Optical, AES : PCM up to 24bit 192kHz Output Voltage RCA : 2Vrms @ 0dBFS XLR : 4Vrms @ 0dBFS Dynamic Range (A-weighting): 128 dB
