  1. Step 4 is why I try to avoid getting drunk.
  2. There's quite a big market for stupid. Anybody want some healing crystals? Salt's a crystal... I recommend crysal fan's eat a bucket-load a day and see how that goes.
  3. According to who and by what measure? Probably the manufacturer by the measure of their profit margins. What is it the Bible says.... "The merchant uses dishonest scales and loves to defraud." -- Hosea 12:7
  4. A1) It only really matters how you perceive them because we aren't listening to your system. A2) Ditto A3) No, AES and Firewire should be 110-ohm, ST and TOSLINK infinite ohm (no wires) as both fiber, USB 90-ohm. Others 75-ohm. If we assume Shannon-Nyquist theory is correct and all these connections support such data rates, then it doesn't really matter which you use if dCS implemented them all properly. (Caveat: and any device providing the data on that connector implemented their feed equally as well) I think you know all this already. So I am perplexed why you ask. TL;DR - these units are for listening and if an input sounds best to you, whether that's caused by cognitive bias or real difference, just use that connection. Some will say USB is the best connector due to the bit-depth and sample rates it can support, as well as being able to support differing data formats, but as you mention, it's not present. Frankly, a connector designed for a definitive use-case and data format is less flexible but more appropriate than one like USB. USB comes at the expense of figuring out what data is coming in, buffering it and having some logic circuits appropriately transcode data to the DAC. It would always be the aim to transform USB audio data to I2S data to feed the DAC, but if that's too far, then AES3 is probably better, but even that depends on what sort of input voltage for data the DAC wishes to see. So it might come down to which voltages are ideal (see table here: https://www.ranecommercial.com/legacy/note149.html). USB uses differential signalling, which is why it's robust in computing uses and can successfully be used anywhere that signalling needs a robust interface. The reason they are less appropriate in cases like audio, is that the receiving circuitry interfaces (e.g. XMOS U208) that can appropriately provide an I2S or SPDIF output, is not in the control of the manufacturer. Either the manufacturer has to engage in a lot of R&D to supplant using an off-the-shelf item like the U208 to deduce an expensive alternative, or they are beholden to what it offers, how to work with it for control software, and its performance characteristics (which admittedly are pretty darn fantastic). But it is an expensive part, and some manufacturer scenarios may lead to additional costs for integration - all of which affect the price the device can ultimately retail at. It also is not nice for them to see newer formats like DSD1024 or MQA emerge and not be able to provide a firmware update to support such, meaning the market appeal of devices using such an interface will be shorter. dCS are one company I know of who usually like to be in total control. (Network Bridge notwithstanding as that contained a Stream Unlimited GmbH Stream 820 interface card and I believe was mostly responsible for why dCS had to abandon getting USB output from working - ref https://community.roonlabs.com/t/dcs-network-bridge-usb-audio-output/47045). Either way, a professional device like your dCS units need to have a wide range of compatibility with other brands of studio gear, which generally use the connections dCS have chosen to implement. As such, they had a wide market in the studio space during their time. Strictly speaking dCS will happily give you their thoughts on which is best if you ask them. I am sure they will say much the same as me - that it doesn't really matter if all your listening is Red Book. If your using higher data rates, any of the other connections supporting those higher data rates will suffice. Properly implemented, there should be no difference unless perhaps needing >10m cabling for an input, in which case staying away from SPDIF RCA in favour of BNC or AES would make sense (see max distance in table of earlier link).
  5. I can see that I will need to re-work and properly finish mine next time around just to correlate with the high bar being set.
  6. I agree with all this. To be honest, I expected the recommendations from TIDAL to learn my tastes and make suitable recommendations. It does not. I've been using TIDAL since 2017, so one would think their software algorithms would have nailed it by now. For them not to work, they must be biased in pushing certain types of music, which typically have no appeal to me.
  7. I think it would definitely be Qobuz - what they detail at track level is more a known commodity, having the catalogue number for a source available. I have Amazon Prime and have played with their offerings. Frankly they are ever making 'free' things come under some paid element again. For instance, Prime used to cover all delivery, for but they started to bifurcate services into tiers such as Amazon Pantry so that they don't fall under the normal Prime remit and thus require additional charges. Prime Music to Prime Music Unlimited is another example of this, and I don't trust them not to re-tier that in future. I've also seen tracks that were available and placed in my collection become unavailable at a later point and no longer be offered on the platform. Equally a lot of hi-res is just a joke IMHO, being just regular 16/44.1 repackaged and often charged for. I just want raw bit-perfect CD-quality or better PCM. I think Qobuz offers this. In terms of how i stream, I use Roon on a bespoke server with enough CPU/GPU headroom to do vast amounts of DSP if I so require it, want to run SoX or HQPLayer, Dirac Live, etc. This feeds my DAC, which is going to be changing (don't know what to). I know Roon supports Qobuz, so that's another reason Qobuz will likely be where I migrate to.
  8. To be fair, at least some are now putting the word "chronicles" in to the subject title as a warning that entering them is akin to the battle for Middle Earth.
  9. True, but I still don't like it. Fortunately every password I have is unique to the website it is related to. But I can imagine others using such a website and then finding themselves locked out of Amazon, or having their GMail account compromised and suddenly all their data is under control of somebody else having handed them the keys to the kingdom. Social engineering hacking 101... how do you get somebody's password? You ask them for it! I'm sure the 2 guys who created Soundiiz aren't hashing passwords and doing anything to adhere to standard practices around such. Where Soundiiz looks problematic is that it migrates playlists, which the main library collection in TIDAL is not. My library is huge and trying to place it in a playlist only makes TIDAL cough up errors. I'd have to do it piecemeal and for that I cannot be bothered. I'm more inclined to see if I can leverage https://pythonhosted.org/tidalapi/ to write some migration code myself.
  10. The intention is to package a higher bit-rate and/or bit-depth in a smaller package. Before encoding as MQA in a studio, it still starts out as a PCM file. Studio equipment doesn't make native MQA files at this time. Thus, MQA is a packaging arrangement and so the input PCM file could always be made available to the public if the studio's and streaming platforms so choose.
  11. Made in 2 hours Not great, tools broke which affected the result. It has not undergone treatment. Weighs A LOT. The intention was to get additional isolation shelves under each unit. Main requirement guiding construction was to be able to handle 2 Pass Labs amps on any shelf, without flexing.
  12. Right... TIDAL 'masters' used to be the MQA version of either the 16/44.1 PCM, or a higher-res mastering. Either way, whatever the MQA file was supposed to represent was something you could get as PCM. I want to be able to continue to get such as PCM. However.... Greygoose said "Tidal are removing the CD quality options on many items and Just leaving the MQA version only" which would mean I no longer continue to receive the PCM versions I want. It's not that I want hi-res or anything like that, but MQA (on the occasions it does sound better) it is normally due to a new mastering from an old master tape of something similar, resulting in a 'cleaner' sounding file compared to perhaps one mastered in the 80s/90s. It's sod all to do with MQA itself and everything to do with a new studio master having been produced, which would be in PCM before it ever gets the MQA treatment. So if these PCM 'masters' are not available to me and also 16/44.1 PCM files (CD quality) are being removed, I may as well try and change streaming service to a service where such aren't being switched off to promote MQA. The question is how to migrate? I've read a Qobuz blog suggusting Soundiiz software, but this is essentially giving your TIDAL login details to a couple of guys who run the website, which doesn't sound very safe to me.
