Some Watkins-Johnson guys snuck it into an old datasheet. National Semi was another company famous for inserting a gag datasheet or two in their databooks.
So as you see the filter choice is invariant in this equation.
But this does show some extreme issues with Optimal transient and to much smaller extent the min phase modes.
Who is the "they" you are referring to here? Do you mean Topping/TPDZ?No as I am keen on having one for future testing. That said, when I asked to buy Topping DX7s, they offered to send one to me without charge. So maybe they do the same.
BTW, they just contacted me back asking me where I am so that they can refer me to local people. Let's see what comes out of it.
Personally I think they can justify the price if their goods are matching in quality. Maybe right now some people are skeptical, but I wrote a nice review of the A30 (subjective ofc) almost a year ago and the D30/A30 stack became quite popular after that. Going on massdrop quite a few times aswell with many units ordered. I didn't intend for any specific outcome, I just shared my thoughts because when I bought the A30 nobody that I could find had one and there were no reviews on headfi or any other forum I Could find.With all due respect to Topping, but they can't price themselves at the same level as well established audio manufactures, even if their products are the same or better.
I still think they will make a lot more money keeping their prices low.Personally I think they can justify the price if their goods are matching in quality.

So now that the DX7 has proven itself, as the D30 has aswell I think that after the DX7S measurements are in and there are some more units tested with similar great reviews they will establish their worth quickly. Especially with their transparency, customer support and hard work at delivering on their promises (atleast so far it seems).

More people will try, and hear that there's not much difference comparing to big bucks audiophile names.
If I have already a high end dac, I could buy D30 just for trying, but I cannot justify buying another expensive Noname Dac, that it will be hard to sell..
RME.Who is the "they" you are referring to here?
Well remember they are testing every device on the analyzer before they send it... That isn't cheap as it adds alot to production time.
I still await you testing for Velvet sound in AKM DAC chips.
I am pretty sure we have tested some. I just don't keep track of them.We don't have any AKM chip measurements yet, then ?

What are some of the most popular DACs that use AKM parts?

Thanks a bunch. Please stay on top of me to document this in my future reviews.From the ones that you've measured
- Schiit Modi 2
- JDS Labs OL DAC
Other:
- Schiit Bifrost (not the multibit)
A DAC that you have bought I think:
- SMSL m8a
And it's also in the SMSL Sanskrit Pro-B.
That one uses an es9028q2m (and es9018k2m for the m8)A DAC that you have bought I think:
- SMSL m8a
