He's pretty much spot on to be fair.

EDIT: sad to see the comments are dotted here and there with various detractors claiming he's either deaf or otherwise doesn't know what he's talking about. But that's par for the course.

EDIT EDIT: hve felt for many years that Sony and Philips sort of shot the industry in the foot with red book CD. CD really is an audio standard which doesn't need to be bettered as a distribution medium for digital audio. Three decades later, an industry which only survives by inventing new better stuff to sell to us has dug itself a hole because we don't need better than a 36 year old standard.

Some say DSD changes the landscape. I don't know if that's true or hype, but I do know that honestly I can't tell the difference between an original source and a top quality 16/44 PCM recording of the same, so I doubt I'd notice any difference that DSD brings to the table.

Ermm... output stage? Filtering? It’s not all about the chip.

The only thing mudding the issue is sometimes you have to buy these so called hi res files in order to get your hands on the best sounding digital masters. Bit annoying, but it isn't going to change any time soon.

Great video my CD player does 12 bit and 24bit but I didn’t buy it because it said 24bit but to be honest I thought the 12/24 bit thing was about music quality .

The current trend is evaluating the DAC chips like changing tubes or tonearm cartridges.

Vladimir when your got a minute you might find this video of interest https://youtu.be/xbLcRrNfdvs

Its basically a 4 part video reviewing the Yamaha A-S1100 right though to looking at all of the components inside what they do and then testing the spec of the amplifier.... I mean a proper test I basically found out only a little bit of class A is used in a class A/B amplifier and the rest is mostly class B .

Yeah. Every class AB amp does few mW first in class A. That's why the amp gets a bit warm even when idle. Thx for the vid. I like these type of vids a lot.

Take also in consideration that many of us are aged around 50 or something. Our hearing also damaged by a few (long ago?) concerts? For most of us 'lossy formats' will even do.

Not necessarily. HF hearing may diminish but hearing, especially through mid frequencies apparently gets better. To do with learning as well as hearing. (Latest edition HifiNews&RR).

My high frequency hearing is clearly compromised these days but I like to think I can distinguish between lossy and lossless. It may not be night and day but certainly enough to warrant a Tidal HiFi subscription as compared to Spotify.

I don't dabble in higher resolution so can't comment but based on Paul Miller's very enlightening measurements of commercial recordings in the aforementioned publication, all is clearly not always what it seems ... . On the other hand, much is and if done properly, makes good use of the digital media.

I have always know this, well most who produce music. I made mention of this year's ago on here. 24bit only makes sense for dynamic headroom when producing and mixing. Nothing new to me.

An analogy I always use for those who don't have production background knowledge: it's like how your maths teacher always told you to do your mid-sum calculations several DP greater than the final answer required to minimize the rounding errors. At its nuts and bolts, digital audio is just numbers, so it's quite relevant.

Some high res music does sound better but i think its the mastering and usually older music where they dont have every track/channel turned up to 11
