Music Server selection guide (sonicTransporter series)
Selection guide · sonicTransporter series
Which music server is right for you?
All three sonicTransporter servers are fanless, run the same audio-optimized operating system, and come with Roon Server pre-installed. They differ in processing power, physical format, and how many rooms they can feed directly.
Start with the questions below, or skip to the side-by-side comparison.
The short answer
Three servers, three different reasons
sonicTransporter i7 (Gen 4)
Start here- The right choice for most listeners
- Libraries up to roughly 30,000 albums
- Intel Core i7, 32 GB RAM — ample for Roon DSP and several zones
- Best value in the lineup
sonicTransporter WhirlWind
Server, streamer & DAC in one- Four zones, each with its own built-in DAC
- Drives four rooms of analog audio with no endpoints or outboard DACs
- 1U rackmount chassis for an equipment rack
- Also works as a plain server — chosen for its zones and format rather than raw processing power
sonicTransporter i9 (Gen 6)
For maximum processing- DSD512 upsampling and heavy HQPlayer filters
- Libraries up to roughly 50,000 albums
- Intel Core i9, 64 GB RAM
- Six or more simultaneous zones without strain
Have a CD collection? Any sonicTransporter works with the External CD Ripper. Insert a disc and the server rips, tags, and files it in FLAC on its own — no computer involved.

Next step
Then choose a player
Unless you are using the WhirlWind's four built-in zones and DACs, you will also want a network player — a small endpoint that sits beside your DAC and receives music over the network. The ultraRendu Plus is where most people start; the opticalRendu Deluxe adds full fiber isolation, and the Signature Rendu SE Deluxe is the reference option.
The Roon product selector walks through both choices together.
