Strong Amplifier, Frustrating Delivery Experience
The Yamaha A4A is larger than an older Yamaha amplifier and sets up easily, with sound running within minutes. YPAO calibration and tweaking took a few days to get right. At 110 watts per channel, it sounds much larger, with very clear highs and deep, fast bass. The Aventage line includes a web editor accessible by entering the unit's IP address on a tablet, phone, or computer, making adjustments simple. The product is loved so far. However, the shipping experience was poor: the outer box arrived opened, delivery was delayed after being miss-sorted, and no signature was required.
Pros
- + easy setup
- + clear upper end
- + deep fast bass
- + web editor for adjustments
- + sounds larger than expected
Cons
- − poor shipping experience
- − outer box arrived opened
- − delivery delayed due to miss-sorting
- − no signature required on delivery

Superb audio and easy operation, with one missing front port
The RX-A4A is easy to operate through the remote or the MusicCast iOS app. The front panel offers only volume and input dials, four preset input buttons, and USB and headphone connectors; a front HDMI port is absent, so a laptop requires a dedicated rear HDMI cable. Audio noticeably improves on an older receiver, especially with concert hall and sci-fi presets. The AI surround sound distributes voice and instruments well, though older stereo content pushes too much voice to the center speaker, making 7-channel stereo preferable. Video management is simpler and no quality loss is observed.
Pros
- + easy to use via remote or MusicCast iOS app
- + noticeable audio improvement over older receiver
- + effective concert hall and sci-fi presets
- + AI surround sound works well for most content
- + simpler video management with no visible quality loss
Cons
- − no front-panel HDMI connector
- − AI surround pushes too much voice to center speaker on older stereo content

Reliable Yamaha Performance with Minor Design Gripes
This Yamaha receiver delivers quick HDMI switching and very good sound quality, even with revealing speakers using ribbon tweeters. The many built-in sound effects are unnecessary but do not interfere with clean audio. The large front volume knob looks odd and seems to compensate for a small, hard-to-read display window.
Pros
- + quick HDMI switching
- + very good sound quality
- + clean sound
- + sound effects do not interfere
Cons
- − unnecessary sound effects
- − large front volume knob looks ridiculous
- − small, difficult-to-read display

Accurate Sound and Flexible Connectivity
This AV receiver delivers accurate sound and connects all 4K devices correctly. It includes pre-outs for the main channels to add external amplifiers, though this is unnecessary for the average home. Network streaming, a turntable input, and digital FM are built in. The audio environments are genuine acoustic mappings of real places and work well for films and symphonic pieces. Downloading and printing the manual is recommended for speaker calibration.
Pros
- + sonically accurate
- + connects all 4K devices correctly
- + pre-outs for main channels
- + good network streaming
- + turntable input
- + digital FM
- + audio environments are genuine acoustic mappings
- + good for symphonic pieces
Cons
- − pre-outs unnecessary for average home
