Can digital get to vinyl sound and at what price?

Reminds of an explanation of dark matter > "it's not dark and it doesn't matter".
...I used to be anti-matter, but I was cancelled.
From the same source also came the implicit confirmation - by a NASA (Artemis) employee, that 'we' have never actually been to the moon :eek:o_O

Am I surprised? Do I care? No, because I still enjoy the Apollo launch videos and the stories of people (on another forum) who witnessed it as a kid,
a few miles from the pad.

LP is not as far behind as you guys seem to think. According to this analysis the relative dynamics and peaks of analog are superior to digital even if the absolute dynamic range is not.

As I said in my previous post this morning, not that the lower dynamic range of LP matters much in practice.

He compares not in a scientifically rigorous manner based on significant sample sizes, but in an anecdotal manner specific manipulated reordings (certainly more manipulated than good classical recordings) on different formats and from there comes to his conclusions.

Not sure that these conclusions are worth much.

But yes, some very good LPs can sound dynamic as hell.

For me the main point is the noise floor of good LPs is surprisingly low and that the dynamic peaks of the LPs can be very high. I think it does demonstrate that there is a reason LP doesn't sound compromised dynamically despite the raw numbers disadvantage. It is not just nostalgia driving the LP resurgence.

I can agree with that main point!

It is not just nostalgia driving the LP resurgence.

The LP resurgence is 95+ % based on digital recordings and/or materings, which is pointless when it comes to a putative "analog" experience. I do appreciate great sounding all-analog efforts like the new Tone Poet series by Blue Note. Yet such efforts are merely a niche in the current LP resurgence.

Analog recordings have unlimited bandwidth.
Digital audio uses sample rate and bit depth to reconstruct the analog signal in the digital realm, creating a fixed bandwidth.

These are the basic reasons why vinyl often tends to sound better in sophisticated setups. It's also the main reason behind the revival of tape.

However, if you are not an audiophile purist (> 80% of the music played at shows sucks) then digital is a great alternative.
A well thought out digital audio reproduction chain will beat a mediocre analog setup.

As far as I'm concerned, the glory of analog lies in the RCA era > simple 3 mic recording setups with minimal post processing.

A fixed bandwidth applies to the human ear and to microphones as well. Especially the microphones in the golden era you mentioned were quite bandwidth limited, with severe rolloff after 15 kHz.

Most loudspeakers at the time covered 50 -10.000 Hz

It's not about bandwidth per se, but how to (mis)use it.

There's a wealth of information available online. The year 1953 is particularly interesting.

You seem to be forgetting the literally millions of records produced before, say 1980, that are all analog. So, I don't agree with this assertion that 95% is based on digital recordings. Sure if someone is only buying new recordings on vinyl then you are right but that is not by any means the majority of recordings available on vinyl.

Came across a thread about NOS DACs in which filtering and grounding were discussed.

Audio Note 1.1x, not the best but overall quite analog sounding.

It's quite minimalist, but the analog filtering is based on some cheap Philips MKT capacitors.

This is a prototype DAC board around the same chip, but with carefully selected (still cheap) parts for the filter:

Peter Qvortrup knows how to finance his collection of Benzes, so you only get decent boards in your Audio Note DAC from level 3 and up.

This is the PCB used in level 4 and 5:

Buy an old td 1541 dac used this nos bridge(remove philips sa digital filterchip)only the clock must wired(2 cable)to them. Sounds incredibile good


Then you put the old opamps out and use these at the specifications you need

Solder the socket into the mods, then you can sell it back in its original condition later if you don't like it

The terms "LP resurgence" or "vinyl resurgence" are mostly associated with sales of new vinyl, as a quick google search will show.

That's indeed a simple and elegant solution.
However, to get the most/best out of the TDA1541A requires quite an amount of work.

I like this one, but it's not exactly minimalist: 1710349509046.png

Yeah with my daughter…probably not so much audiophiles
