Ah, no worries, units are important...Yes, sorry. Typo. meant to write 'bits', not 'dB'

I am in the process of trying to design one with an engineer - will see how far I get…
Bet he doesn't like being crammed into that little box...
Your engineer (and perhaps you) will already know this, but this article includes a bit about segmentation and how it helps (and hurts):
Digital Audio Converters (DACs) Fundamentals
Author: our resident expert, DonH50 The purpose of this thread is to provide a quick introduction to digital-to-analog converters (DACs), the magical things that turn digital bits into analog sound. Previous threads have discussed sampling theory, aliasing, and jitter. Now we’ll get down to the...

Hahaha! Thanks for the article!
Maybe if you drank too much, after expecting it to sound any better.
People buy stories.
I owned both (including the Serene) and sold the Holo Audio to return to my Topping D90Se/Pre90/Ext90 setup. The detail retrieval of the latter is far greater. However, it probably comes down to taste - as one Holo Audio champion favours them over Topping alternatives as the latter are seen to present too much detail for his taste.
I'd love to see anyone tell them apart in a controlled test.
Aaagh, that old chestnut.

The quest for evidence to back up the endless claims never ends. It would if someone could back them up, but no one ever has.
The idea around this place is to help people see beyond the stories. Buying stories can get expensive.
True, and unarguable. The test results for the noted groups of equipment would seem to confirm this.

That's the gold standard in scientific disciplines.Aaagh, that old chestnut.
Measurable, repeatable and objective distinction or subjective repeatability?

Would be interesting to see the measurements of this DAC if you were to plug in a standard power supply, if that's possible.

I know the review for this was some 6 years ago but it 4vrms on XLR and the manual mentions 5.8vrms.
So which one is correct?

Well thank but that’s what I wrote.
It’s in the manual.
hi I have a weird problem on my May when using with gaia ddc
1. on i2s-1
do I have a faulty i2s port 2 because I have been using port 1 all the while until recently switch to port 2 due to new stiff cables
any help will be very much appreciated.
1. on i2s-1
- setting the matching pins out will playback both dsd and pcm without any problems
- setting Mode 0 on gaia to match May dac pins out
- dsd will playback fine
- pcm will show the max rate 384k but no music
- lower rate to 192k and there will be music
- setting Mode 2,3,6,7 on gaia which does not match May dac pins out
- dsd will either sound off left and right or there will be static coupled with a very thin music
- pcm will playback fine at any rate from 44.1K - 384K
