What changed—and whether the advice changed
These are evidence or compatibility changes, not theme-update timestamps. Manufacturer claims remain distinct from independent verification.

About the evidence
How to use SoundPath Lab
What is SoundPath Lab?
SoundPath Lab is an independent audio publication covering streamers, DACs, amplifiers, headphones and complete systems. It is operated by FASTHiFi Technology Co., Limited. Read about the publication and our ownership and commercial disclosures.
Has every product been tested?
No. A product record or comparison does not by itself mean hands-on testing. Check the evidence label, sources, test conditions and unresolved gaps. Manufacturer specifications, owner reports and dated hands-on observations are identified separately. Read our review methodology.
How do I check streaming compatibility?
Start with the exact model, hardware generation, firmware, source app and connection you intend to use. A supported format or protocol on one input does not establish support on every signal path. Use our compatibility checks and product records.
Where can I find manuals and firmware?
Use the manufacturer's current source for your exact model and revision. Our official manuals and support sources point to brand resources. The tracker separates release information from independently verified fixes; we do not host firmware packages here.
