I'm pretty new to this; I finally decided to dabble with a decent set of cans and I managed to grab a set of HD650s in the recent Massdrop order for December, and I grabbed the Magni 3 / Modi 2 Schiit Stack to go with it. Mostly I'm looking for anything obvious to do/look out for. So far, it certainly sounds great; bass is clearly down compared to my old non-amp'd PC-360s, but I'm not terribly surprised by that. Things I've noticed: -Headband is tight; assuming this will break in over time. I vaguely recall the PC-360s being this way when it was new. -Less bass, but bass sounds great (and scales with volume) -It's pretty wild being able to crank the volume knob and to not hear any distortion. -I'm already hearing new things to old songs randomly, which is strange. What I did for setup: -USB cable to Modi -RCAs over to Magni (just some basic ones; hoping to find a good short set at some point) -Plugged in, installed drivers from schiit's site, rebooted. -Set Modi as default audio device, set audio to 32-bit 192000Hz under advanced -Set Windows to 100% volume and adjust volume via the Magni's knob And that's about it. From what I can tell, people argue if burn-in is needed and I'm probably in the camp of "it doesn't matter". I assume I don't need to worry about trying to set anything in a software EQ? Volume set to 100 and just let it ride? Any stuff to watch out for would be helpful. I'm also not trying to buy a shitload of cans now, but who knows :lol: Thanks dudes!
