Astra vs Expert Pro on paper

[ada]

I know sound can't be compared on paper but here are some interesting differences I am seeing in the web site.


Comparison data comes from Devialet and it is for Astra Dual vs 440 Pro:

Capability differences:

Signal-to-noise ratio: 117db vs 133db
Distortion at 10v: 0.0004% vs 0.00025%
Output impedance: 0.0057Ω (1kHz) vs 0.001Ω
Damping factor: 1400 vs 8000

Input differences:
AES/EBU: N vs Y
DAIR: N vs Y
DSD: N vs Y
Speaker output: from 8Ω to 2Ω vs from 1Ω to 16Ω

Connectivity differences:
Tidal Connect: Y vs N
USB streaming: 384kHz vs 192kHz (but internal DSPs are 192kHz on both)
USB: C vs B
Bluetooth: Y vs N (capable)
Wifi: 6 vs 5
Trigger In/Out: N vs Y

Features:
SweetRoom: N vs Y
