Overpriced for its specs, for sure. Now, when it comes to ADC and DAC, in a perfect circuit (therefore, in theory) you should be able to perform the perfect encoding and reconstruction of a 22.05 kHz sine wave at Red Book spec CD Audio sample rate and word length. But reconstruction filters aren't perfect and they have a transition band that can be problematic, even if - indeed - we are talking of distortion phenomena at the very threshold or beyond the hearing abilities of most listeners. For this reason, and to alleviate the burden on having to realise near-perfect reconstruction filters, it's been deemed a good compromise (in terms of storage cost) to do ADC with an additional octave worth of wiggle room devoted to the transition band of the reconstruction filter. This compromise is 96 kHz ADC, and for good measure, extending the word length to 24 bits makes better accommodation of the human hearing's propensity to notice with more acuity, amplitude variations in quiet audio passages, than in loud passages. This non-linear perception is called mu-law and it is used in telephony systems as a companding mechanism that fits a better signal in a lower number of bits. It is often misunderstood that the intention of 24/96 digital audio is to reproduce ultrasonic (!) audio frequencies ; whereas in fact 24/96 is intended to provide a better signal processing margin for the audible range, which extends to 20 kHz in the best cases (most listeners can't hear a thing above 16 kHz). 24/96 also improves the recording and reproduction of low-frequency square waves, or wave shapes that have a lot of high-order harmonics. The ears (and loudspeakers !) will do their own low-pass filtering, but having a wee bit sharper impulse response is never a bad thing. The paradox is that, as long as you're not doing anything stupid, 24/96 is actually a cheaper way (save for storage) to achieve great audio reconstruction, than doing Red Book (16/44). As for the pipe dream of going all the way to 768 kHz, just because AKM, ESS and Burr-Brown chips can handle it ; we're well past the law of diminishing returns. Audiofools who claim they can hear this sort of stuff need counselling. Very high data rates in DAC chips were engineered to support DSD audio, but that's another story.
A long time ago I Radio/TV Technician and i hat alot of costumers in HIFI audio. Mostely stupid guys who are paying alot of money for esoteric technology. It's looking pretty much tha same today. This was the reason for me to give up my job and looking für better chances with more salary. I'm still laughing about all those stupid poeple.

Cute story for you... I used to work for a very large electronics company, in their fledgling computers division. One day we got a shipment of "solar powered calculators" ... the first of their kind. They were advertising them as light activated with no batteries to worry about and selling them at $29.95 each. ... Nobody wanted them... litereally nobody! Finally, after a gilding mistake that died one of the case backs gold during a spill, they hit on the idea to "up the game". The multiple skids of calculators were shipped out, the backs were removed and electroplated with a gold finish and they were repackaged in a flashy new box. When we got them back they advertised them as "Executive Pocket Computers" and sold them for $249.99 each.... They sold out in 2 weeks. Some people are such easy marks....

Mr Mellor, This is off- topic and may not be appropriate in this reply area. Please consider exploring an HDMI to I²S converter. Source attributed to @anadialog “How to send high-res audio from a Bluray /SACD/DVD player to a DAC via HDMI“, at or near the 6:52 mark. My use is with the Apple TV HDMI output for conversion to digital audio coax, meanwhile allowing the HDMI to pass through to the television. The audio coax is connected to an external DAC and continues with RCA cables to a 7-band tone control to finally join with the AVR aux in. Thank you for all the cold spectrograph to spectrogram analysis warmed with charming wit.
I'm probably underappreciating the significance and complexity of this. All I know at the moment is that I have a rough-and-ready spare-room system sourced from an Amazon Fire stick going to a splitter box that passes HDMI to a computer monitor and separates out the audio to the amp. $19.99, or am I missing the point? amzn.to/3VSUJxP
Mr Mellor, you seldom if ever miss the point. My point was off mark. The fool meets Sir George Henry Martin CBE. The foolishness displayed forever on the Internet. I had stumbled upon a blurred copy of a bad sketch written on a cocktail napkin with unclear directions. Your reply was that of a true gentleman.
Isn’t a real IEM a custom made earphone, made first by pouring a putty into your ear canal then molding a hard plastic version of it, that fits exactly? Many costing $1K and up? In any case that is what musicians use. Since when did simple earbuds with a variety of rubber tips come to be called IEMs also? Those provide poor isolation and often fall out of the ear. Real IEMs never do. In fact you have to pry them out.
You raise a good point here, or rather build on mine. I suspect that nothing that either of us says will make any difference and whatever is called an IEM will be an IEM.
My cheap Loxjie D40 Pro has much better specs and sounds so much better than my Schiit Yggdrasil top of the range R2R, and yes it's maybe not as nice as this one but being smart is not always related to esthetics ;-)

Great Review as usual, You are the Most entertaining reviewer I've ever come across on RUclips,
My kitty Lou Lou can hear 40 hz. Lou Lou is happy with my older Audio Alchemy.
I had plenty of fun with portable DAC/amps on my headphone journey. Started with the legendary FiiO E07K . Always thought the Diablo was ridiculous.

Concerning a very wide frequency response someone once said, (I forget who unfortunately) “The wider you open the window, the more the muck flies in.”
