CHORD ELECTRONICS DAVE

[Reactcore]

hi. I see a few that have Dave and DC4 are selling. I am curious what they are getting in to? It would seem even with the DC4 upgrade they have found something better? The upgrade did not deliver the sonic lift they were hoping for? thanks for any insight

Its called upgraderitus.
They NEED to get something new ..only to find out later what theyve lost..

I think you need to distinguish between posters who are just searching for gear that they can live with and enjoy for many years, and posters who regard hifi as a hobby and want to try a new dac/amplifier/headphone/iem every few weeks or months.
Those hobbyists ensure that there is a continual churn of owners trying to sell/buy gear.

my preference would be to build a great stack and use that... unless there is quantum lift. I have a Dave for awhile and was considering the DC4. For those that have it in % how would you rate the lift? Also it seem encouraging that it apparently seems to benefit the amp as well and creat a more meaty sound which I prefer?

thanks

I think @Reactcore is a good person to interact with.
During the past 3 weeks I have been reading quite a few old amplifier design articles, and this article reminded me of the development work that Reactcore has been doing. The article can be downloaded from https://worldradiohistory.com/Wireless_World_Magazine.htm

thanks will read!

anyone have direct experience comparing the dc4 to the new farad setup for the Dave? how close are they?

It's almost 30 years old.
Class A/B used to be poor because of cross over distortion so IMD used to be horrendous, but it's not an issue for many many years now.

Ps. I'll ask you this. So you read and get information about newest tvs or computers from papers that are 30 years old? Probably no, a lot has changed since then.

Ps2. Class A is another folklore that stays in audiophile community as the time pass.

The laws of physics haven't changed in the past 30 years.
The competence of designers, plus the tools available (eg LTSpice) may have improved.

So designs don't change?
We are still using same designs as we were 30 or 40 years ago?

I'm done here.
So why you are using Dave? Just use a DAC from 20 years ago. It's the same, the law of physics haven't changed, right?

looking at the farad power supply.... I am in the US would I get the 100VAC or 115VAC ??

1/2 the price. how close to DC4?

thanks

You obviously are not understanding what I have posted.
The laws of physics (and electronics) have not changed.

You still see amplifiers marketed/sold which have distortion of 0.5%, even though 30 years ago it was demonstrated how to design amplifiers with distortion in the region of 0.003%.
Check the spec for the new Chord Bertii amplifier, distortion of 0.0008%, which must be close to the practical limit for commercial analog amplifiers.
The analog output from Mojo 2 is even lower distortion.

The laws of physics (and electronics) have not changed, but a lot of designers must be constrained by design manhours cost, manufacturing testing cost, component cost, design competences, etc.

If you want a deeper understanding, try reading the articles (available from the same webpage) by Douglas Self (1993/1994), regarding distortion in power amplifiers.

Your logic is strange, I don't get it, it's just not logical.
Ps. It's end of my spam posts. Bye

Oh man, you are making arguments like it’s 1990. Chord amps have historically sounded bad. I don’t expect anything better from them regardless if their “spec” is amazing, which is meaningless for audio applications.

Chord dacs and CDPs have historically been fine but never amazing or TOTL. Dave didn’t change my mind in anyway about Chord.

SR-1a/b’s bass extension can largely be improved by EQ, magnitudes more than any amp paring will achieve.
Only if you tend to listen very loud this approach hits a limit.

It‘s quite common, if you read though the postings, that the Raal ’phones, like many others, benefit from EQ.

I’m typically listening at upper medium level, and my EQ (orange plot) follows the Harman curve quite well, while extending to 25 Hz, although I have the flaps open so they are about 1 cm from my ear lobes.

The measurement below was made on my own head, so quite realistic:
Microphone in the outer part of the ear channel, plots with no compensation.
