I am thinking to get this set up 8030's with iLoud Sub after buying a pair of faulty kh-120 ii recently
Do you produce mix or master? have you ever had neumanns to compare?
Hi h2opt. Sorry I have no experience with Neumanns. I can DJ poorly on a good day

No music production experience. and if I did and my opinion was worth listening to. I wouldn't be a guy who is using 2 of the cheapest entry level products in combos with one that has been recently released.
I choose the iloud as non GLM sub was out of stock at time and more expensive, and going GLM would have meant I would also have probably upgraded to 8331s at a total cost of 9 to 10 times that of the just the iloud taking shipping and tax into account at the time.
What I didn't appreciate from researching the 8030 on here was 8030 are very well built, solid 5kg each, have metal grills and have taken some minor to moderate spills with no damage caused. I would have expected damage to happen to if they were not metal enclosures with metal grills that all the cheaper alternatives seem to be (The neumanns look robust too with their grills and are aprox 10% more expensive than the 8030c here.) With these products, because of the high price performance ratio, (including the neumanns (if you buy new and not damaged) it is not going to be a bad purchase. If this system is an upgrade in price for you (it was for me) you will not be disappointed as the quality was a massive jump for $$$. and adding the iloud was a massive jump too.
A wee warning for others is. As with all speakers they must be placed at an optimal hight to your ears for peak performance.
Do not place directly on a desk. They need stands. And stands that don't have the tray extending in front of the speaker. 3 non Genelec table stand options for 8030c seem to be (in the southern hemisphere):
A concrete block sitting on a cork tile with either layers of cork or mdf/wood/ply glued to the top to get the correct hight. or a GRAVITY SP 3102 style stand with the top tray removed and replace with mdf/ply that doesn't stick out. or 3, The GRAVITY SP 3102 C B may also work with no modification at first glance.
.
Another of my learnings. The difference in quality of music file and components is now noticeable.
Please excuse the language, but crap in crap out applies to the 8030cs. low quality mp3s sound low quality.
Low quality dj gear (that includes any Pioneer DJ or AlphaTheta DJ gear that is not in their premium priced category) used with the 8030s has a noticeable decrease in sound quality.
A really handy feature of the iloud sub is the multiple inputs that I can leave always connected if I want to.(which I do) it means I never have to change channels via my dac or remote or my channel switcher unless I want to play pure vinyl outside of my dj setup or a cd player or old music server, which I don't tend to
I run a usb cable from my laptop to it for general listening,
XLR inputs to a Dourk mc103 pro channel switcher between DJ set up /DAC preamp, music server / analog setup (which I leave on dj setup.)
Bluetooth for my phone (or laptop) if I want to play and change music further away than my usb cable length,
Regards
