I did a search, and I didn't find anything related specifically to this. I actually have two questions really.
I was enlightened to what impedance is and about how impedance imbalance occurs with a splitter. This can be solved by having both sources on at the same time, but I don't really want to have to think about that.
I've been looking around at potential switches, and this one seems to be of good quality from a decent manufacturer.
My concern and question, however, relate to what I read on a page related to another, similar switch.
In the third blue box down, to the left of the model and price, you'll see mentioned about how a "ground loop isolator" may be necessary if their switch introduces noise. After reading this, I started looking at various 3.5mm GLIs, and I happened upon a review someone gave one that mentioned, while the product did work at getting rid of or reducing the noise, it also somehow affected the bass.
I'm doubting that person is an audio professional of any kind, and maybe they just think they're hearing a change. But this still got me thinking of whether or not the GPI could be affecting the signal's quality.
So, what do you guys think about the first switch linked? Should it do the job without affecting signal quality? That second page says the GPI usually is not needed, but do you guys have an opinion on that as well?
Secondly, I have an ODAC, and was wondering if the output from that is safe to split in this way to both my computer speakers, which have their own amp in the sub of the set, and my O2 amp. I know the ODAC is meant to be a headphone DAC, but does it matter in this case? And, again, can this weak signal be split?
I'm a bit of an audio nub and just getting into this, so take it easy if anything I said seems obvious or obviously wrong.
