How did you test that? On my two pairs of 8330A (one pair with 7360A) using I toggled between the analog and digital (AES3/EBU) input with no discernable difference in hiss. This was with both analog cable connected and disconnected. I've not tested that using an AES3/EBU cable connected, though.
On one pair I've turned down the volume via GLM and the hiss is a little less after 10 db down or so. I've set it to 25 dB down to better gain match with my RME ADI-2 DAC FS that has auto reference level.
I've not heard the 8030C, but the hiss on the 8330A is only noticeable on quiet evenings about 70 cm away, and that is if I listen for it. But I do notice a little hiss when the 8330A is turned on. The sound character of the hiss is not objectionable to me.
The self generated noise level of 8330s is indeed lower than on 8030s.
It can be reduced even more by using the digital inputs - as now also the internal AD conversion is bypassed. And, in addition GLM offers you extended options to control the sensitivity which will further reduce the noise. If your digital source is providing the AES/EBU signal at full level for the highest resolution you should control the volume via GLM - and you will end up with levels of -30 to -20 dB.
I think it's really worth checking out - in addition you can profit from all of the advantages of the SAM technology and GLM. Doing a measurement at your listening position will make it possible to precisely use the internal DSP-filters to compensate for the influences of your room and the positioning - providing you an even flatter and reliable basis for your listening. All settings can be edited to your needs.
The GLM Set is 359 Euro on Thomann.de, do far less than 600.i think you should just start with those Adams T5V with topping E50 dac = 300 + 250€... They are perfect for gaming, movies and so on if you were to buy 8040 you would gain a bit more and precise low end a more precise mid (this however can be pretty pointless if your room is not acoustically treated ) you will get better depth and better high end (for example vocals on).
or you could go digital but 8330 costs 750€ per unit and you need GLM kit 600€ new (it adjusts the sound to your room so you get almost perfect response in mid and bass BUT depending on your room glm after bass neutralization can take away all the energy in bass region which you will need to add with external EQ like Eapo which makes it absolutely useless without Notebook/PC) and you still need to feed digital input to speakers so you wont need DAC but you will need something that takes USB and outputs AES. You can get something like this at eshop but it will cost another 200+€.
If i may recommend i would just buy Adam T7V 180€ x 2 = 360€ + Adam T10S (SUB) 430€ you can adjust volume to taste and E50 250€ maybe some cheap diffusers for ceiling and gg... Genelec for TV use is overkill at least to me because you will miss out a lot if you won't listen to Genelecs at near field position...
oh thats right you can use +3DB low shelf but that's not enough in my experience, especially when whatching movies and you want that cinema effect when lows are kicking in your chest without the need of sound deafening levels thats as you said a preference thing but glm is perfect imho for mixing mastering not for watching movies or playing games. again my opinion... i dont care since use PC for both listening to music and watching movies so EAPO is not a problem for me but for some users that just want to watch netflix from tv and use optical out i don't think GLM will sound enjoyable
I'm still undecided but I'm more inclined towards getting the 8030 or 8040
Are the 8030C and the 8030 CP the same model?
Thanks for the clarification haha
I wish you could get the black versions readily instead of having to have them custom-made in Finland then shipped out to you. Much better than the standard grey.Genelec have several color options for the 8030C and the P after C is for the Anthracite (grey) color and W is for white. Otherwise they are identical.
