HDtracks is proprietary aiff (apple) - booo !!
Same SQ as flac , which is compressed and open source. yeah!!
Both are lossless.
Actually have 60K+ of all three types (320k mp3/flac/aiff). Some mp3's
sound better than some flacs , source is god ... garbage in-garbage out.
Have redundant flacs - aiff -waves(.wav) .... identical.
The software (or plugin) that converts these files for your soundcard to use ,
and the D/A in your sound card (or external amp DAC) is a big
factor in end SQ.

I've tried several file type from WAV to MP3. Which do you/others think are the best of the non-compression, loss-less types besides WAV files?
I've been using AIFF and FLAC mostly for all my portable stuff.

It was again a sardonic tongue in cheek response to the list Sy put up, I have an eclectic collection of music, probably more so than many, as even though in my 50's I still listen to Radio 1 (in the UK) so I can keep abreast of the terrible pop music these young uns listen to today...
Wow! A 0.95mA Iq class B, 2V/uS opamp....? JC must must be tearing his hair out

That might be a part to upgrade.
let see.... didnt someone say .5-1v/v was adequate?

Technically , wav/aiff are truly uncompressed (PCM). but flac is like a
zip file ... as it also becomes PCM at output.
FLAC can be compressed 50% with same SQ. I'd rather have 20K tracks
than 10K on a single HDD.
Nearly all my HQ digital is flac , converted a whole library classical collection
to flac for personal use. Convert the flac back to CD , bit perfect.

Nah it will be pretty much the same, all the DACs I have seen the insides of are nothing to write home about.... Mundane layouts etc.
Ohh yes, most new audio products that see the light of day seem so broken that any diy-er with a hot soldering iron can unlock Nirvana from them
And yes, 1V/uS most probably is enough but such numbers completely destroy any street cred with the cognoscenti, of course!

To be able to make meaningful comparisons, you need to compare two identical geometries/processes: there are many other factors influencing the end result.
Note that higher beta is correlated with stronger Early effect

The Pono has discrete output stages. Four of them in fact as the Pono has a balanced output option. Since the chip is a quad, they may just be using it for DC servoing. Though I suppose it could be for I/V conversion. In either case, they're not what's driving the outputs.

How can I possibly know without trying it, Scott? In general, I would expect it to be near the original because the ingredients should be fairly easy to obtain, but the rest is cook's work and taste while adjusting.
You know, when you dig a bit deeper you may find that countries which had never had any meaningful historical meets over anything just happen to have similar dishes. An example - Scotland's haggis, etc. and Serbia have a few dishes which are similar, not the same, but similar. Both are a delight to have.
This is a bit like music, or specifically, musical instruments. Drums, flutes and bagpipes seem to be common to every single nation in Europe, despite variations on the basic theme.
This never fails to cheer me up, because it shows that we are all similar, despite the politicians' attempts to make us all appear very different, local customs notwithstanding.
Thanks, I had servoing as a thought after posting that dismantle link. It was just too bad if Pono used that OP as output.

Actually, I still listen to classic FM broadcasts day in, day out, 8 AM to 12 PM. And there are moments when I get caught out on visually checking whether that's my FM tuner or my CD player I'm listening to.
That's possible because locally I have 3 radio stations (out of 62 stations overall) which do give a damn about the outgoing signal, 2 of which are dead set against MP3 and the like, they broadcast only proper CD material off real CDs. And they do have their glory moments.
Unlike the modern junk kids are served as pop, and especially RAP. Locally, we have an additional category we popularly call "turbo folk", designating music which uses classic folk music lines, but adjusted to modern instruments by just about every idiot on the block. Most of it is plain and simple junk, designed to cover up the singer's lack of vocal talent and to highlight her boobs and behind. Unfortunately, boobs and behind can't sing.
Although not as minimally recorded as your work, my favorite foot tapping Mulvey tune is Old Simon Stimson. Just love everything about that song.
Funny as the Pope on fire.

Really? Not this one?

Thanks Frank for that YouTube link....i watched bits and then the last 5 mins or so....I have to watch my data usage
.Anyway, yeah, been there done that with modifying laser pickups, I can get better sound than that $2000 glass cd disc (you cannot be serious !) for close to zero cost.
That said, it is most interesting that the actual cd material can make a sonic difference...I have gold metallised discs and they have another sound again.
So, yes, the point is made that 16/44 can be good, bloody good, and better than many give credit to.

We've been here before, marce, a few times ...
You sort of explained it in your next post,
Something as simple as a layout, and/or quality of power supplies is enough to do it - in the latter area a number of members have done recent work, and managed major gains in subjective quality.
Cross-interference shouldn't be a factor but the reality is that it is ... enough to be audible ....
There is no way to cheaply emulate an expensive circuit.
No way to to package 1 pint of beer into a 1/2 pint glass.
In that sense, John Curl is right, in my view - there really is no substitute for a well done discrete ciruit, beause with it, the designer keeps full control of each and every parameter of the sound it produces.

Thanks John, I understand who Fremer is, I was taking the mickey, a subtle tit for tat to Scotts cheeky comment....all in good fun.
I was serious about the unconscious foot/toe tapping though, it's a good system when it takes you there.

That would be especially true if cost is the main selling point of the circuit.dvv said:
Just remove half of the water. You can always put it back again later. This is what people who like 'tube buffers' claim to do with (digital) music.
I read somewhere (possibly in this very thread) that chip designers have access to matched devices (or predictably mismatched devices) which allow circuit techniques that are simply impossible with discretes. Of course, they also have to face things like thermal feedback which discrete designers can avoid.
I suspect that nostalgia is the main driver for discrete circuitry. Just like some people prefer valves, or even low mu valves driving interstage transformers. It may also be a preference for 'hand-built' over 'factory-built' - although few commercial circuits are really hand-built, as it is too prone to error and sample variation.
