New DAC comparison chart (we'd love your feedback)

[Wes]

I have a question for Stalker81, aka Audiophool Nuto"Science":

Did the Sandman send you over here? aka Alexis Keitel?? He's the one you need to treat with psychiatric drugs.

It has always been like this, the old charts were also rated by percentile score. So I just copied that. The only difference is that in the old charts only the best values were shown, and right now I'm also showing values for other inputs/outputs when available. I agree that everything in blue and green probably sounds exactly the same if its a recommended product (might be other issues if its not).

Glad to see someone implemented this in production, with Amir's blessing.

You can set the color fields to be a quantized set of N (dis)similar colors, which would differ from Amir of course. Or a continuous band. Or remove color entirely, since the value it represents is on the chart already. (Said Edward Tufte.)

 

[Wes]

It would be great if there were info on listening tests done and posted...

esp. one between a high priced and a low priced DAC

Hi @Koeitje,@pozz

Nice job. One suggestion: The names of the devices could be hyperlinks to the reviews.

You can create a 'Dashboard Action' in Tableau to link a URL field in the dataset to the name of the device

The Red/Orange/Green colour scheme can be difficult to differentiate for people with colour blindness

Hi both, thanks for making this. It's really very useful and the UI is a great leap forward for members

BTW, I'm an Analytics Architect and chair a Tableau User Group so I'm happy to help out with any advice or development issues

EDIT- Missed the line in your original post

'Would it be possible to create a scatterplot with the price and SINAD variables on the x/y axis? It would be a quick way to assess 'bang for buck''

There won't be a relationship between price vs. performance but applying a quadrant might help members identify High Performance - Low Cost vs. Low Performance - High Cost etc. insights quickly

@VizardofOz Thanks! I built the Speaker Review Index and Electronics Review Index, which definitely need work to become more user-friendly. If you don't mind I'll send you a PM about those specifically.

This is awesome. Thanks for putting in the work to organize this data.

WEIRD! When I go to
https://www.audiosciencereview.com/forum/index.php?pages/Audio_DAC_Performance_Index/ using my Chrome browser, I get a blank field.
Using Microsoft Edge - I get the chart. I wonder if some extension or setting in my Chrome browser is blocking the HTML for the chart?

There are certainly differences between these DACs as can be seen here. And, you can see that price does not necessarily equate to technical performance - the $130 Topping E30 returns much better test results than some of the very expensive DACs listed.

I would love to see a blind shootout - multiple listeners, multiple DACs A/B'd against each other - to see if we can actually hear these differences. For example, one of those Audio-GD DACs vs. the Benchmark... it seems you SHOULD be able to hear such glaring differences in measurement - but CAN we?

It is an embedded object so if your security level is too high, it may not show up. It works for my Chrome browser.

 

[milosz]

Hmmm I've set all my Chrome security settings to the minimum it allows.... still no table. But if I open https://www.audiosciencereview.com/forum/index.php?pages/Audio_DAC_Performance_Index/ in a Chrome Ingocnito window, it works. There are too many blasted settings in Chrome. HAHAHAHA

I'm using Chrome and the web page opens and data is available.

Great work!
Thank you!

Given the number of items tested and the very small, unreadable type at the bottom of the chart...

I suggest a change in format from horizontal to vertical layout.

Do you mind taking a screenshot of the type you mean?

 

[Wes]

well, now I can't get it to display at all

 

[Max]

Very nice and thanks for the work !

My Emotiva DC-1 was measured by @amirm back before the current Sinad ratings.
https://www.audiosciencereview.com/...surement-and-review-of-emotiva-dc-1-dac.2306/
Is there any way to incorporate this data into the newer listings?
TIA,
Sal

It's in here: https://www.audiosciencereview.com/forum/index.php?pages/Audio_Equipment_Reviews/ but not in the comparison chart. In almost all cases I haven't used the data generated by Amir's old analyzer to keep the comparisons accurate. A few times I used the output impedance numbers, and headphone power once.
