Audio System Guides
Start with the system you are trying to build, the equipment you already own and the connection that must work. These 25 guides use the same scenario vocabulary as System Builder.
Choose the closest system goal
SCN-01
Add AirPlay 2 to an existing amplifier
Reuse a healthy amplifier and speakers; add one verified AirPlay 2 endpoint.
Open guide →SCN-02
Add Google Cast to an existing amplifier
Reuse the system and add a Cast-capable network source.
Open guide →SCN-03
One streamer for Apple and Android
Require both AirPlay 2 and Google Cast without buying two endpoints.
Open guide →SCN-04
Play a NAS or local library
Prefer wired networking and a verified NAS, SMB, or local-library path.
Open guide →SCN-05
Add a Roon endpoint
Choose a current Roon Ready endpoint and match its output to the existing system.
Open guide →SCN-06
TV into an existing stereo
Use HDMI ARC/eARC where possible while retaining the amplifier and speakers.
Open guide →SCN-07
New TV and passive-speaker system
Build a complete HDMI-controlled stereo around passive speakers.
Open guide →SCN-08
TV with powered speakers
Minimize boxes while preserving TV remote control and stereo separation.
Open guide →SCN-09
Computer USB DAC into powered speakers
Use a real USB Audio input and one clear volume-control path.
Open guide →SCN-10
Computer and full-size headphones
Match a USB DAC/headphone amplifier to a wired over-ear headphone.
Open guide →SCN-11
Drive 300-ohm headphones
Require sufficient voltage headroom rather than relying on connector type or marketing power.
Open guide →SCN-12
Low-noise portable IEM system
Prioritize low noise, appropriate gain, and portable USB operation.
Open guide →SCN-13
Wireless gaming headset
Match platform, low-latency link, microphone, and fallback connection.
Open guide →SCN-14
Turntable into passive speakers
Build a phono-correct path through an amplifier into passive speakers.
Open guide →SCN-15
Turntable into powered speakers
Use a built-in or explicit phono stage before a powered stereo pair.
Open guide →SCN-16
Turntable and headphone listening
Create a valid phono-to-headphone chain with sufficient drive.
Open guide →SCN-17
Desktop near-field system
Prioritize short-distance placement, compact size, USB, and sane budget allocation.
Open guide →SCN-18
Small-room stereo
Balance compact speakers, moderate power, and placement flexibility.
Open guide →SCN-19
Medium-room complete stereo
Match source, amplifier, speakers, and optional subwoofer for a normal living room.
Open guide →SCN-20
Large-room or high-headroom stereo
Favor amplifier and speaker headroom; do not infer fit from room size alone.
Open guide →SCN-21
Add a wired subwoofer
Require a verified subwoofer output or compatible variable line path.
Open guide →SCN-22
Apple multi-room system
Use AirPlay 2 or a clearly compatible native ecosystem across rooms.
Open guide →SCN-23
Mixed-platform multi-room system
Require both Apple and Android casting paths and explain grouping limits.
Open guide →SCN-24
Minimal-box all-in-one system
Prefer a streaming amplifier or powered speaker route with the fewest new boxes.
Open guide →SCN-25
Reuse existing speakers and replace the front end
Keep passive speakers while comparing streaming-amplifier and separates paths.
