Hello there !
Here we are, I have received, set up and calibrated everything so I can start sharing my experience with you

I apologize for my english that could be a bit strange sometimes, i'll try my best !

Installation and setup
Genelec setup
- The speakers (8331) are pretty heavy with their stands, it is not very easy to manipulate them, I need to be carefull when doing so. The 8331 take some space on the desk
- The subwoofer is not too big, I like the size of it compared to the neumann one which is bigger
- Installation of the calibration system is not difficult, RJ45 cables were delivered with the speakers and i really like the fact that you just have to plug the GLM set to one speaker, then each speaker to an other one.
- I can put the GLM set on the desk, keep all the stuff connected and re-calibrated whenever I want to.
- The speakers didn't work until I calibrated them, I don't get why but it could have been anoying without GLM set (it must be possible to use them without GLM anyway)
- You just need the cables of your basic setup to calibrate them (4 XLR cables in my case)
Neumann setup
- The speakers (KH 80) are pretty light and easy to manipulate, I put them on iso acoustics stands and it is quite stable, not as stable as the Genelec but really easier to move. The KH80 take quite small space on the desk.
- The sub is quite big, it is not too much but I feel the difference with the Genelec one. The Neumann sub should have more power so it is understable i guess
- Installation of the calibration system is not a pain but way more difficult than Genelec. I got to buy RJ45 cables and plug each of the 3 speakers to my internet box which is on a corner of the room.
- I cannot re-calibrate the setup as easily as the Genelec because I have to unplug the XLR cables between the DAC and the sub in order to plug the cables between the audio interface and the sub. I also had to install a software to install the interface USB drivers but it was easy to do.
- The speakers were plug and play, I didn't have to calibrate them or whatever and I could have easily listen to music without any calibration.
- You need more cables to make the calibration (4 basic XLR cables as Genelec, 2 symetric jack to XLR for the connection between sub and interface, and one more XLR from interface to microphone)
--> In my case I globally prefer the Genelec setup for my use on installation and calibration setup, but the Neumann setup clearly also has good points.
Calibration
Genelec setup
- Calibration cut a lot of bass in my case, sound is way less boomy and more detailed
- The software is easy to use, I easily found online documentation where I wanted more informations. The main functions are easy to use but the software seems to have sooo many features. I'll need time to try everything.
- Everything on the soft is described, I have the feeling it is not only done for pro but also for newbies like me
- I can save several setups on my PC, then switch from one to another (I have one calibration for my desk and one for my couch), switch from one to another is easy while the GLM set is plugged on the PC and the speakers are plugged to it with RJ45 cables.
- The calibration is pretty quick
- I can easily see the calibration which is done
- I can store the calibration in the speakers, but I also can use a software calibration on Windows while storing an other calibration in speakers for other uses from my phone for example (a bit useless though)
- I can store a dB reduction in the speakers, so it won't be too loud even with my phone
Neumann setup
- As with the Genelec the calibration cut a lot of bass, sound is way less boomy and more detailed
- The software is quite easy to use, but I didn't easily find the online documentation I wanted to
- Software has a bit less explanations than the genelec one, but it's very okay
- I haven't find how to save a setup and switch from one to another, I am not sure it is possible. For now if I want to change my position I would need to re-calibrate the setup so I just don't do it
- The calibration is pretty quick
- I can see the calibration which is done and the calibrated curve, but I can't see the "uncalibrated" curve at the same time
- I have to store the calibration in the speakers, I cannot save it on my computer (or I didn't find how to do it)
- I cannot store a dB reduction in the speakers. I would not miss this feature if i had not tested it on genelec speakers, I miss it on Neumann though. I had to remove the Genelec dB reduction to have the same sound level from both setup.
- I've heard there is an iPad application where you have more options with the speakers, I feel sad this is not available on Windows.
--> Genelec is clear winner for me on this. GLM software is really well done and have a lot of options.
Misc (stand by mode and power consumption)
Genelec setup
- The on use / waiting for sound power consumption of the setup is 17W. With high volume it goes up to 18/19W
- I can set the stand by mode to switch after 2 minuts
- The standby mode is removed as soon as sound goes in the speaker, it takes 4/5 seconds to wake up and make sound
- Stand by mode power consumption of the setup is 2W
Neumann setup
- The on use / waiting for sound power consumption of the setup is 40W. With high volume it goes up to 41/42W
- From what i've read I cannot change the stand by mode timer without the iPad application, default timer is 90 minuts without sound to set the standby mode
- I haven't wait long enough to set them in stand by mode, I put them on OFF when i stop using them, but I will try tomorrow and edit this message if I can
- Documentation says the power consumption of the setup should be less than 1W in standby mode, I haven't tested it yet though
--> Genelec is again clear winner here. I know this part could be useless for a lot of people here but I personnaly do care about this. The fact I cannot change the standby timer on Neumann annoys me a lot. I also find the KH 80 to be quite warm while they are plugged in.
----
I know I haven't talked about the most important thing yet : the sound quality. The fact is I need a bit more time to test them and give you a feedback.
For know I cannot say one setup is better than the other one, I really like to listen to both and I need more time to find the + and - of them.
If you came here for sound only i'm sorry ... I'll hard try them and come back with more stuff to tell, feel free to ask me anything you want me to try (or even songs to check details etc etc).
Stay tuned ! ;-)
