■ The catch — co-equal billing, always
It won't play true hi-res. Denon's new Home 2.0 speakers stream 24-bit/192kHz; the Era 300 tops out below that. If you subscribe to Qobuz or Tidal for lossless masters, some resolution is left on the table.
Dealbreaker? Runner-up №1 — the Denon Home 150 does full 24-bit/192kHz hi-res ↓

Runners-up — if your needs differ
Adjacent verdicts — same method
Traps — this verdict avoids
Ecosystem lock-in
Sonos, Apple, Denon HEOS and Alexa multiroom groups don't mix. Your first speaker commits the household to one of four incompatible ecosystems — you can't put a Sonos and a HomePod in the same group, ever.
Bluetooth ≠ multiroom
Real room-to-room sync rides on Wi-Fi. Bluetooth-only speakers can't synchronize across rooms at all, and any setup of 4+ speakers wants a mesh network to stay locked together.
The hi-res illusion
24-bit/192kHz hi-res needs a compatible speaker AND a Tidal, Qobuz or Amazon Music HD plan. Budget speakers still cap at 16-bit/48kHz no matter what you stream into them.
