  1. Two things (in addition to bodily parts) that nobody is allowed to touch in my house: My bikes My speakers Well, yesterday I noticed one of the speakers had been moved. I knew I heard something was wrong, but it was easily confirmed from the pattern on the wooden floor. My wife (I haven't yet had a chance to fill out the divorce paperwork) gloated that she had moved the speaker a tiny amount two weeks previously while cleaning (as if), and that it had taken me this long to notice. Never-mind that in that timespan we had a few other things going on, like the Rel subwoofer flaming out, the car's transmission flaming out, and other demands. The cleaning excuse seemed implausible. If ever I need to hide something from my wife, I just put it in the vacuum cleaner. Not to mention the mountains of dog hair. The house is a perpetual standoff, and I usually flinch first and do the cleaning. So I think she moved it just to fuck with me, which, after age 50, has taken the place of ... well, never-mind. She seems to think it is funny that I re-allign the speakers with a laser measuring device. Now I have to re-callibrate the room correction. At least she hasn't questioned why I had the back-up subwoofer stashed in the garage.
  2. Greetings! I'm a grad student at MIT, and I'm working with a startup here that's developing a new high-end home stereo system. We're looking for feedback on the latest features of the system, and would love for you to take this quick 5-minute survey. I'm happy to answer any questions you have about the survey or the technology we're developing, so do don't hesitate to ask! https://dsc4026.sawtoothsoftware.com/xYXqPLYNTC/cgi-bin/ciwweb.pl?studyname=xYXqPLYNTC -Ben
  3. Hello I've read a lot about this very interesting theme "RoomModes". One helpful instrument is a calculator like http://www.bobgolds.com/Mode/RoomModes.htm My room has not a rectangular shape the ground plan is more like a L. So what dimesions are essential? Calculators ask only for room length and width? Any thoughts appreciated.
  4. Hello, The system: MacMini with Audirvana DAC LessLoss 2004 Pre-amp Nagra PL-L Power monoblocks Nagra MPA Speakers Vivid Audio V1.5 Subwoofer JL-Audio F112 (with dedicated power line) The problem: Even though these are all high-end components with an amazing resolution and a sound I love, I'm fighting with the fact that the system's performance is being very limited by my current living room. I tried several full range speakers and they all had serious bass problems. Apparently my living room is the culprit. So I decided to go for a pair of monitors and a good subwoofer with room calibration. That kind of made it bearable to listen to music there. But still... my system doesn't sound relaxed. Thanks to the subwoofer my main problem is now with the higher frequencies. I find that when I start raising the volume, the music quickly becomes tiring and confusing. So I end up avoiding music with lots of dynamics or feel tempted to start lowering the volume. But this is not acceptable for me. An acoustics specialist went to my home and after measuring the living room, said its proportions are very bad for listening to music. He said the first thing to take care of were the first reflections but I have a window on one side and a sliding door on the other, both right where treatment should be applied, which makes it a hard case. Still, he said I should install diffusion panels on the back wall and on the ceiling. I'm very reticent to invest so much money into something which will have a serious aesthetics impact and without the possibility of testing it. The salesman is suggesting that I buy Amarra iRC saying it probably solves a good part of my problems. But not only I'm fond to Audirvana, I also don't like the idea of being stuck to Amarra. And then I heard about Dirac Live. The questions: 1. How much of this will Dirac be able to solve? Will it reduce the impact of first reflections for example? 2. Won't the Dirac algorithm reduce the quality of the result (detail, etc), since it's transforming the information? 3. Would it still be advisable to put diffusion in the back wall for example? (I consider putting it in the back wall, but I really would like to avoid installing it in the ceiling, even though I hear it's much more important there) 4. Will Dirac Live (2 channels) work fine even though I have a subwoofer or will I need the full version because of it? 5. How will Dirac's room correction relate to the subwoofer's room correction? Should I turn of the subwoofer's room correction? Thanks in advance! Nuno
  5. Audirvana and Room EQ Wizard

    Greetings! I've been reading alot about integer mode on the Mac lately. I tried bitperfect, but it couldn't enable integer mode on a Mountain Lion laptop, but Audirvana did. When I finally got integer mode activated, I noticed an increased bass response almost immediately. I remember turning up the gain on my subwoofer last night, and I was definitely turning it down on the same songs after I got this working. I subsequently read somewhere (i can't remember where) that increased bass response is typical when activating integer mode. I have a umik on the way and my master plan is to run RoomEQ wizard to get some recommended parametric EQ settings, then use the AU ParametricEQ in Audirvana to implement it. I'm trying to find the holes in this plan before I start buying stuff so now I have a couple of questions. I purchased AudioHijack and Bitperfect before I had this all figured out and now it looks like Audirvana will do what I want, but want to be sure before the trial finishes. - Room EQ Wizard doesn't look like it will work in integer mode and I don't think I can use pre-recorded test tones with it. Since its recommended EQ settings will be based on a non-integer-mode measurement, will that incorrectly EQ Audirvana if I use the Audio Unit eq plugin? - I believe AudioUnits is a Core Audio function. If I activate an eq plugin, will that pull Audirvana out of integer mode or out of the iZotope thing? I'm basically trying to decide if I can do this all with software or if I need to get an external EQ.
  6. I just came across the Dspeaker Anti-mode 2.0. I am intrigued, because it has an USB asynch input and a digital output. So basically it can be used as USB-Spdif converter including room correction. I like this idea. I also like that they are correcting only up to 150 Hz or so. But... Does anyone have experience on how well the usb-spdif conversion part is implemented? How transparent it is? I am a bit worried seeing that it only has a toslink output. I would much prefer a properly implemented XLR or RCA output. Any thoughts? Are there comparable products that take an usb input, do room correction in the digital domain and output either usb or spdif?
