  1. That doesn't follow my understanding of things. iTunes has it's own sample rate converter that is separate from core audio. Or more specifically, iTunes uses core audio, but it doesn't use the system settings at any given point, it calls the libraries to set bitrate on startup, and if you change settings after the fact, then you'll get itunes resampling followed by default sample rate conversion which can be worse. http://lists.apple.com/archives/coreaudio-api/2008/Jan/msg00273.html
  2. Mr. Reading Comprehension, I never said it was just for itunes. But if you do what I said, it will have iTunes actually do the upsampling when it's playing back.
  3. To get bit perfect output on the mac: In the application "Audio MIDI Settings" which is in the Applications->Utilities directory, plug in your optical cable, set the output to digital output, and set the bit rate of the digital output to the rate of the files you're going to be playing. Then launch your playback application. That's all there is to it. You also have the option of letting itunes do the upsampling, which it does a pretty good job at doing. In that case, just set the sample rate in Audio MIDI Settings to the rate of your choice (probably 96/24). Then launch the playback application. If you launch the application before changing the settings, you get much worse results.
  4. I'm amazingly lazy, but it'd be easy enough to verify. Take a digital recorder. Hook it to the mac's optical out. Record a track. Transfer the track back to the mac. Invert it, and then sum it with the original track. I'm not going to do the work, because I'm happy with the sound I get from my mac, but if you're concerned about the bit perfection of the mac, it's easy enough to test.
  5. Apple did some tweaking with core audio at one point, but certainly current versions of os x are bit perfect if you set them correctly. You have to start itunes after setting the bit rate, and then everything works hunky dory.
  6. I'll take you up on that If you can mod an srd-7 to 620v for me, that'd be great, and I'd probably actually mail off your lemos Actually, those are going out this week, I promise
  7. Ok, the hunt begins.
  8. My signed/limited copy of Snow Crash came while I was at canjam!
  9. What would be the best cheap solution to powering the esp950s?
  10. An Error Has Occurred! You are not allowed to view the Downloads
  11. I'm interested in the 007t. My esp950s need something like that
  12. I'm going to need to talk to someone about a nice but inexpensive 620v stax/koss amp
  13. I watched 6 episodes of firefly on the various planes this weekend, and I'm sold. It's a good show. Some extremely funny moments. The acting in the first couple and the movie was terrible, tho.
  14. Vicki's R10s weren't at all bass light. They were quite nice.
  15. I sometimes use the butane one. Works ok.
  16. I'd just drop the 1/4 adapter in the mail and be done with him.
  17. Just replace unbalanced ins with unbalanced outs
  18. Here's how: buy inexpensive gear that fits in the budget. Listen for a bit, sell it. Keep proceeds in a paypal account. Always buy with the account linked to the bank account, always sell with the other one
  19. So I can get the VaughnMod TooleAudio Balanced Mosfet Preamplifier back from the jam of cans.
  20. Stranger starts better than it ends, so don't let it end
  21. That's a nice lens

    Child model. Like for the gap. They like using ugly kids too.
  23. I got a luxman integrated amp for $100 that I'm VERY happy with. When I check ebay occassionally, there are similar deals to be had. Here's one, dope
  24. We'll be outsourcing the casework, for sure.
