You might wanna try that, iFi themselves are also saying multiple ones can neutralize noise better, although I wouldn't go further than 3 units as in my experience there is a thing as too much filtering which makes the audio softer. I'm getting three of them this Friday, if i hear an improvement I'll be very happy but if i don't I'll probably end up returning them. It really differs too from person to person, location, noise creating devices in house or out of the house etc.hmmm what i think of Qv2 in my system are nice touch i was very impressed by it ,firstly i thought it was just snake oil then the retail person which i knew just let me took back those for trial test say i could just bring them back if i don't like....but after i plug in those i realize my system sounded damn good the effect is better than i upgrading power cord....i heard things like vocal having more depth, soundstage is wider and small things like birds chipping in the forest or person when tying her hair i able to hear them before that...are not that pronounce.....i thought i was maybe because i knew i added those....so might be mind trick....so i ask three of my friend come to try and they could tell me what they heard with and without those the difference then i was convince to brought those.....now is on my system not gonna remove those.......then few months later i saw these ifi ac purifier which looks like QV2 so i decided to give it a try see if the effect were the same....but i only heard slight difference when using it so maybe because of using only one?
As always YMMV, it's always good to try some stuff.
