First sorry for my poor English, but i'm not sure if what I just found out is what I think it is. Quick backstory, I'm planning to buy studio monitors (KRK ROKIT 6) and I wasn't sure if I can just connect them to to iMac headphone output with Dual RCA to Stereo Mini PW-MP-05 http://www.planetwaves.com/pwProduc...feet&sid=fbd4b275-4ab4-4005-8168-ccf21791d9a4 or do I really need an external audio interface, get now just Focusrite Scarlett or wait and save up for apogee one or element. I have most of my music in 16bit 44.100 khz alac anyway but starting to get some 24bit 9600 khz. Googling only found out people saying external DAC is must because computer headphone outputs are very bad, but then I found this Apple page https://support.apple.com/en-us/HT204392 that says The headphone output supports a stereo data stream at bit depths of 16, 20, or 24 bits per sample and at sample rates of44.1kHz or 48kHz, or 96kHz and more specs. (interestingly for iMac Pro just "high-quality sound", so is iMac Pro DAC downgraded?) So maybe for now it's fine and not very expensive dacs like Focusrite Scarlett may not be that much better, and I can save up for apogee one with which I could use then the same Y cable.
