TONEWINNER AT-600 Processeur Audio-Vidéo Préamplificateur Home Cinéma

Great AV-processor with Dirac for incredible value.
The Tonewinner AT-600 is a solidly built AV-processor with a ton of connectivity and a full set of dirac-features built in.
My system: 7.2.4 with Tonewinner 7 Ch-Amp and NAD 4-Ch-Amp and B&W for speakers.
First impressions:
The case of the processor feels solid, all the connectors are gold-plated. The unit looks nice and clean with its big volume-dial in the middle and the two displays to the left and the right. The displays are big and can be set at different brightness-levels. The remote has a metal top face and is sturdy but it does not allow for the selection of all inputs. You have to use the smartphone app for that.
Setup
Before anything else, hook up the processor to the screen and set the speaker-configuration and the number of Subwoofers. You cannot configure this in the app.
I last made a full Dirac setup with an older system more than 6 years ago and should have remembered how important setting all the speakers to a similar level is. So: do this first, if you don't want to have crazy bass-levels! For Dirac, you have to have a special microphone that is NOT included. The included micro only works with Tonewinner's own room-correction system! The Processor and the Computer to which the micro for Dircac is connected have to be in the same WIFI-Network.
Sound and Picture
The sound after the correct dirac-measurement was really great, clear and crisp. The spacial impression of the soundstage was both deep and wide. I lowered the bass-levels slightly, but this was the only adjustment I made.
The picture quality is as expected, since I leave all the processing to the players and the projector and the processor has to just forward the signal.
Operation
The remote-control gives you direct access to three inputs you can define yourself. To select other inputs you have to use the input selection key that gives you the list of all inputs on screen you can select from. The Input selection through the app works better.
Input switching is quick and reliable. The sound- and picture-formats are correctly identified and displayed on the left screen.
The startup of the processor is sufficiently quick. There are two graphics on the screen when powering down. it would be nice if the user could customize them.

Conclusion:
The AT-600 is a great piece of AV-gear at a very good price considering the quality, connectivity and the fact that Dirac Live with Room Correction, Bass Control and Active Room Treatment are included. The build-quality seems to be very good, and the performance is more than satisfying.

As for any niggles, they are minor and few:
- DLNA-Compatibility would be nice, since the AT-600 has already the capability to play music-files from SD-Cards and USB-Drives and also has a permanent Network Connection.
- Not compatible with Logitec Harmony, but that is just a statement of warning to buyers that have a harmony system. Tonewinner cannot be blamed for Logitec abandoning its product.
- Allow for the reassigning of the symmetric outputs of the central Ceiling speakers as SW 2 and 3. This way a 7.2/3.4. system could be hooked up fully symmetrically.

Recommendation:
Go for it. If you have an extended AV-System and a tricky room that needs a good sound management, the AT-600 delivers at a price that is actually astounding.
