    DAC recommendations?

    For me, there is no audible difference. Maybe if your Wifi is struggling to reach with sufficient signal level, you might find a difference, but I doubt it. Wifi is quite capable of the data bandwidth needed for audio. Still, if the ethernet port is there, why not use it.

    DAC recommendations?

    One of the "extra" functions provided by the moOde software is upnp/dlna. So, this means you can run bubbleupnp, connect to Tidal to choose your music, and send the music to moOde as the renderer. MoOde then sends it to the DAC via the USB interface. The upnp/dlna stuff is all via...

    DAC recommendations?

    No need. You can run the rPi headless (without a display) and interact with it via a web interface on your phone or tablet or computer.

    Question regarding amp/dac power ratings

    If you get 96dB from 1mW from your phones then you don't need many milliwatts for a very loud sound. You are going to get somewhere between 6.7 and 30mW from that amp, so you have plenty.

    Power Regenerators, conditioners...

    - and indeed they do. What they have designed in, is sufficient for most cases. It will be the rare situation where someone has power that is so bad that it needs to be reconditioned for use.

    Turntables?

    Having spent a lot of time listening to and tweaking big idler drives, my comment on wow & flutter is that it only needs to be better than a certain amount. That amount for me is somewhere under 0.2%. By measuring the speed variations directly, rather than the pitch variations in playback...

    Audio Grade Capacitors?

    I don't know if it was real or not. The point was it was different to my expectations

    Audio Grade Capacitors?

    Right, but again, that was not the point. I replied to the statement "If you spend the $ and do all the work to get that amp percolating like new, your expectation bias and (near) human brain is going to make you hear a huge improvement in the sound no matter the reality. ;) Win Win Win."...

    Audio Grade Capacitors?

    Yes, I agree, but my reply was intended to refute that positive expectation bias is always the case. My expectation was for zero change. Instead I not only heard a change, but I liked the change. My expectation, remember, was that it would sound the same. The outcome, probably imagined, was...

    Audio Grade Capacitors?

    How about when I replaced some coupling caps with a different type, hoping to prove it makes no difference, but instead, got a big surprise? The change was quite noticeable. Whether it was an "improvement" only measurement would show (is the response flatter?) or personal preference may dictate.

    New DAC comparison chart (we'd love your feedback)

    Maybe there is more data to be added. I don't see my little Fiio E10K, yet it was reviewed/compared here https://www.audiosciencereview.com/forum/index.php?threads/review-and-measurements-of-jdslabs-odac-rev-b-compared-to-fiio-e10k.2068/

    Audio Grade Capacitors?

    Totally agree. However, this being so, it also indicates that replacing new capacitors with better quality new caps can also make a system sound different, even better. Just as a deteriorated cap will measure and sound different in some instance, so too new caps with different construction and...

    ASR "Myth" regarding "discrete" circuitry...

    You could go for the tube version of an IC. There were tubes with multiple elements. One such had a triode and 2 output pentodes - a power amp in one glass "IC". https://www.radiomuseum.org/tubes/tube_ecll800.html

    My First Tubes

    Wrong term. Tubes just need to warm up, and it only takes a minute or so. Once operating temperature is reached, no further "burn-in" is required for them to sound good. On the other hand, some report a change in character to the sound after some hours use. It's all a bit nebulous as to...

    Mono, stereo, multi-channel

    Maybe the AV terminology is now best. 1.0 mono 2.0 two-channel - stereo 2.1 adding a sub 5.1.2 five channel, sub, and two height channels https://www.bigpicturebigsound.com/What-Does-5-1-2-or-7-1-4-Mean-for-Surround-Sound-Speakers-Dolby-Atmos-and-DTS-X.shtml
