I told myself I would only get one iem per month, and I ended up getting three this month. The IE 600 and Ej07 aren’t even a week old, so there’s still tons of listening to do. The only other iem that I have my eye on is the Monarch mk3, but that’s still on back order on headphones.com. Other than that, I’m pretty happy with this collection :)
That is really really hard question. I guess I just listen to a song, and wonder how it would sound on this particular iem. I only use one Dac/Amp because if I was worried about the amp, I would go down another rabbit hole. My original plan was to get an all rounder, the u12t, then one that did bass really well, another that did mids really well, and another that did treble really well. I know it’s not specific. I probably wouldn’t have so many iems if there was a demo place near me, but unfortunately there isn’t, so I’m more or less buying blind. Obviously, I look at the all the reviews, video or written, to sort of get an idea if I would like it or not. I agree, it’s 100% not practical to own so many, but I don’t know why I haven’t brought myself to sell them on headfi or somewhere like that.
