我都有 777（塞左入迷你倉，唔知放壞左未 ），要注意 777 因為用左 K2，冇記錯如果個 source 信號係 over 20bit 部 777 係 lock 唔到，好似碼率個 KHz 都有限制，基本上係只俾 CD 用，依個亦係我打左佢入冷宫嘅原因，你求其借部 streamer 試左先安全啲

Although I cannot guarantee compatibility, Lumin U1 (MINI) is designed to output 16-bit for 16-bit music when volume control is set to OFF and re-sampling is set to OFF.

If you have to have 16-bit output in downsampling Hi-Res (e.g. from 192kHz to 48kHz for DAP-777 compatibility), I can try to make a custom experimental Lumin firmware for you to see if it helps.

Also note that DAP-777 AES is pin 3 hot.  Lumin AES is pin 2 hot.  You'll need to set the DAP-777 to invert phase.

AES metadata format is different from SPDIF / BNC.  If you experience AES issues you could also try the BNC or SPDIF outputs of Lumin.

If you subscribe to Tidal HiFi (HKD96 per month), turn Lumin MQA Setting to Off, so that it gets 16/44.1 version of the Tidal Masters you choose to stream.

Thx
I may change DAC in cow tear

I played 24-bit files on Accuphase DC-81L (20-bit) and got no problem.

Accuphase DC-81L 有 K2 interface？

It's not. It was Accuphase' s own discrete 20-bit DAC

係囉，所以金仔同到唔代表樓主用到，因為佢指明用 Remiyo 777，佢嘅問題只係同 K20 Interface 有關，唔係同 DAC 芯片有關，只要唔係 K2 Interface，係 16Bit 至 20Bit 嘅舊 DAC 都有可能 support 到 24Bit（主要睇用咩接收 IC，例如 CS8414），K2 Interface 有啲似一份異步 reclock，所以會有規格限制

I didn't mention Remiyo or K2 could play 20-bit.  I don't care about that.
