For NXP ICs 74AHCT595D vs 74HC595D the main differences are:
1. Maximum frequency SHCP / STCP: 170MHz vs 50MHz
2. HIGH-level input voltage: 2V vs ~3V (74HC595D is less stable with a 3.3V Input logic level signal)
3. Different power consumption

Sincerely, Alexey Galkin.
okay thanks.

but how about the effect to sound?
if 74HC595D can be use, it will far cheaper than AHCT

Based on DSC2.5.2 design, what should be the sweet spot in terms of dsd stream speed? I mean, should I send "native" 2.8MHz or is it definitely better to upsample to an higher ratio ?

For DSC2 it is recommended to use DSD256 or DSD512.

Are there any measurements that shows the behaviour of DSD64, DSD128, DSD256 and DSD512? I'm not looking for any special, just curious to understand if I need to invest in hardware capable to push up to higher DSD rates or remeins calm with lower profile Pc ...

Got a msg from Amanero, they suggested <firmware_2004be> as natural evolution of older 1099c ...

firmware_2004be still has problems on the DSD512 under Linux.
If you have Windows - 1096c is the best option.

Ask at Vit123.
He went a long way. He has a lot of experience in subjective comparison.

The only measurements I've seen was done by Jussi Laako with DSC 2.5. His recommendations, based on measurements, was DSD256 as a "sweet pot" for DSC 2.5.

With HQP I've tried DSD256 and DSD512. My opinion (quite subjective):
1. DSD512 is better then DSD256 with the same filter+modulator. The difference is not big, but quite noticeable, even in blind tests. More "analog" sound, I'd say.
2. Full-length filters in HQP (poly-sinc-xtr (-mp), closed-form, poly-sinc (-mp) ...) is MUCH better then -2s or -shrt (short) filters. The difference is audible at once and very big.

So, the reasonable solution is in using poly-sinc-xtr (-mp), closed-form, poly-sinc (or other full filters) in DSD256. Very high SQ.
My old I7-8700 with fast DDR4 did it (computer cost ~ 1500 USD). Don't forget SoC as NAA. I am with Odroid C2 for now.

To handle DSD512 with poly-sinc-xtr (-mp) and closed-form you'll need much more power. Cost will be 3 times more.

If you won't invest to a new computer, try offline upsampling by using Saracon (up to DSD128) or AUL converter (up to DSD1024). I slightly prefer the last one.
Aleksey Galkin says that has got a very good results with special version of foobar + sox resampler + ASIO Proxy.

But bear in mind - all are very subjective
