I have used NFB 28 for half year. Not a single problem occurs.
Very nice product. I did one firmware and driver upgrade.
Nice to pair with yamaha monitors set.
Mainly use it to watch movies and listen music.
I like sound using NFB 28 xlr cable connected to HS8 and HS8s subwoofer.
Totally I need 4 xlr cables. The sound is very nice compared to very high end headphones.
The volume can be controlled using universal remote to NFB 28.
By the way the white version of HS8 is sexy!
Honestly, all Audio-gd products are good value. From their lower offerings to their hi-fi beasts. They all sound good, especially the ES Sabre chips [and 1704 chips, of course].
The software maybe isn't perfect, but the price/performance more than makes up for it IMO [in general].
Wow, those new cases look really good.
Reducing the intensity, you may want to check with Kingwa, he should be able to advise, provided you are technically sound.
No issues at all with the ventilation spacing, i had similar spacing, and left it on all the time. Sounds good readily! or you could just move to the top tier of your rack anytime if you dont feel comfortable.
