    It reminds me of Schiit Mani 2. Amazing!

    Sounds like you went inside my head and designed exactly the product I wanted. About the Phono input: does it have the same specs as the Fosi X5? Will it have the same sound quality?

    Thank you!! It's nice to hear that is still on progress. Take your time. We prefer a good, functional product even if it's launch is delayed, than a bugged product. Can you give us any other info? Which is the current status of the product? do you have any specs already decided? Do you have any...

    It seems like you forgot about this product. You aren't moderating this thread anymore (there is a spam post just before this one, 2 weeks ago). Will this even be in production?

    In the end, what inputs and outputs will it have? Is the Bluetooth still LDAC and aptX Lossless? And is the DAC chip still the AK4493SEQ?

    Why do you need LPF? Doesn't your subwoofer has it's own LPF/crossover? 😮 What is the model? Taking out XLR input makes sense if you use the internal DAC (we shouldn't forget that this product is, in it's essential part, a DAC) instead of other source as a DAC. Other sources don't use XLR, just...

    Keep the analog input circuit, don't use ADC. Those who use a turntable with external phono will be grateful (including me!).

    That is the best approach. Normally the subwoofer itself has it's own LPF function. The important one is the HPF for the main speakers. Of course, HPF needs to be switchable to full frequency signal, for all those who don't use subwoofer and want all the frequency into the main speakers.

    1. Well, I think it's weird to have to prefer between a second RCA output and to have a subwoofer out, but for me, it does work. I don't have nor pretend to have a subwoofer. Is the SUB RCA output single ended (mono) or stereo? If it's stereo and the LPF can be turned off, then it works as a...

    What's the logic behind XLR output but no XLR input? All chain needs to be balanced in order to avoid interference, that is the essence of balanced audio. Without XLR input, XLR output becomes decorative. Considering that, you could then take out XLR entirely and use just RCA. That would be...

    I've looking for similar products in order to be able to centralize my sources. My ideal setup goes like this: Turntable + CD Player + Streamer. Turntable goes to external phono preamp, streamer goes to external DAC through optical. Also TV goes to external DAC though HDMI or optical 2. And...
