High-Quality Chips: AK4499 is AKM's flagship model. With current output architecture and 4-channel design. The D90 MQA parallels the channels of the AK4499 in pairs for better performance.

High-Resolution Music: With the support of AK4499 and XMOS XU216. D90 MQA can support 32bit768kHz and DSD512 resolutions, and the data magnitude and resolution are far beyond CD and SACD. Customized German Thesycon driver(Win7 and higher).

Bluetooth 5.0 Tech: D90 MQA is equipped with CSR8675 chip, supports Bluetooth 5.0 well, supports LDAC/AAC/SBC/APTX/APTX LL/APTX HD and other audio encodings.24bit96kHz HD transmission can be achieved under LDAC encoding. (If you don't need Bluetooth input, you can turn it off in the menu.)

Input Interface: AES,USB,OPT,COAX,IIS,Bluetooth input. Among them, USB, IIS support 32bit/768k DSD512 input; AES,OPT,COAX support 24bit/192k input,BT supports 24bit/96k input under LDAC; IIS input can be set in the machine, compatible with most IIS signals on the market using HDMI transmission.

AK4118 Receiver: It is currently the lowest jitter S/PDF receiver with good compatibility. It is used for D90 MQA OPT, COAX, and AES receivers, all supporting up to 24bit/192kHz.

D90 MQA has a fully balanced structure,it is compatible with both balanced and single-ended outputs.You can choose any one output,the other is closed,or both.It is especially convenient when used with other devices.

Switchable Global Voltage: AC 100-120V 50/60Hz uses 115V,AC 220-240V 50/60Hz uses 230V.

DAC Filter Mode: D90 MQA provides 6 different PCM filter modes to choose from, there is always one for you.

Bluetooth Decoder Application: Connect your mobile phone, tablet, and laptop's Bluetooth to D90 MQA,and it will become your BT decoder.If your device supports LDAC transmission,you will get better sound effects.

My Topping DX7 Pro from ShenzhenAudio was delivered literally an hour ago *facepalm* Oh well, I'll enjoy this for a bit and probably upgrade to a Topping stack with this and the A90 as both appear to be fantastic units.

Thank you.

hmmm... interesting indeed, soon you will be mine.

Sounds good so far! Big thanks at to the team over at Apos Audio for getting this review sample out quickly, In terms of size it's a smidgen bigger than my RME ADI 2 but it has a nice heft or weight, Excited to hear some MQA out of it here shortly

Waiting for the review.

Right! Soon, I'm happy to say it just simply ran via USB with my 1+ 7T Pro 5G and Usb Android Player Pro! An I got MQA confirmation on both the Software display and D90 display window. An as some one who listens to MQA some what exclusively through Android [I usually have a LTE Tablet in my office] it means a lot to have straight forward plug an play MQA playback

Mine also. It has shipped on friday from Hong Kong to Europe. I just have to buy xlr cables in the meantime and EU plug for THX AAA 789 that I'll pair with D90 MQA, and then I'm all set.

I ordered it on hifigo.com and they notified me when they shipped the package. And before that on 21st of April, Topping announced on it's facebook page, that D90 MQA is released.
