Seems to make sense to start a digital room correction (DRC) thread, so here goes. I was only recently able to set up an entry-level 2-channel system at home. I built an Overnight Sensations kit, added a Parts Express 10” subwoofer kit, and hooked up a JLH69 amplifier from Nobsound, a PLLXO from Parts Express, and a cheap-o Parts Express plate amplifier (for the sub) to my Gummy & Saga. This setup sounds pretty great for the relatively low investment. Just having the soundstage actually 6 feet in front of me vs. maybe a few inches outside my eye sockets is a dramatic improvement in terms of enjoying the music. @shotgunshane had some good things to say about the Dirac live DRC system, and that piqued my interest. At the same time my Raspberry Pi-based streamer was starting to get crashey and generally flaky, and I got gifted a Schiit Eiter. This perfect storm plus an unused 2011 Mac Mini made it possible to set up a computer-based media/streaming server. I’ve set it up with Audirvana+ (which I can remote control from iPhone), Spotify (also can remote control from iPhone), and Rogue Amoeba Airfoil (for when my wife wants to stream music to the Mac Mini via airplay). Enter Dirac live. I downloaded the trial software-only version on a lark to try it out. Daaayum! It makes a dramatic difference in integrating the subwoofer and improving the soundstage. I’ll try to add some more detail later in terms of room layout (VERY funky), speaker positioning (near field) and all that, but for now I’ll just say it’s all kinds of sub-optimal. Dirac live resolved a serious midbass peak, a lower midrange suckout, and some seriously 3-blob, flat imaging. On my near-term TODO list are re-doing my Dirac measurements with greater precision, and cross-checking Dirac’s theoretical improvements with what Arta actually reveals in terms of before/after. Thus far Direct live software-only has been stable and adequately performant on the aging 2.5GHz i5 processor of the 2011 Mac Mini, but I really want to torture test it a lot more before I claim that it’s reliable (and before I throw down ~$450 for the license).
