  1. I have to live in suburban Sydney, and my partner won't move out west. On the other hand I am allowed my own money! Then again, if I did have my own room, it would take about a week to be completely full of someone else's books.
  2. Oh, it's budget, is it? I always thought that was speaker size.
  3. Is that the only door behind the speaker? Careful...
  4. What they do is important. In this case, they appear to contain a substance that emits "far infrared radiation", or heat. I'd want to know how much heat, before I stuck one of these on a component that is already running very warm or hot.
  5. So, these stickers are coated with material that heats the audio components and scatters radiation around?
  6. And, wouldn't you hate to be the reviewer to comment on the excellent build of a product, only for your readers to complain about the part that goes up in flames a few months later?
  7. Why make the claim without evidence? And what is the difference between a subjective and fundamental difference anyway? Either the soundwaves have changed, or they haven't.
  8. It's not impossible for some capacitors to go through changes if the equipment has been powered down for a long time and then powered up again, or so I'm told. Then again, it could actually be your brain doing very normal things. A lot of "burn-in" is the listener adjusting to a slightly different sound. And have you been gradually changing the volume to get it "right"?
  9. OK, but it doesn't tell us what the DAC at the end of the MQA decode is receiving, which I presume is what Sime is talking about.
  10. It's not easy. You can find out the bit rate of the original recording on the 2L website sometimes. The more recent tracks are in DXD, 352.8/24 originally so full decoding of these tracks should be at 352.8/? (bit depth dependent on coding). The Bluesound only plays back up to 192/24, so you should hear 176.4/? in practice. You can of course download the testbench files and pay to download others at their site if you want to compare the MQA with the high bitrate original through your 2Qute, or 192/24 versions are available to play through the Bluesound. MQA are covering their tracks a bit with bit depth. It has to be well under 24 bit to cover the "folds" and other information, and they are apparently increasing the effective bit depth with dither, which is itself a compromise. One thing I haven't seen are distortion measurements for MQA playback and I do wonder if they are out there. So I presume that their answer is that it is blue light MQA - assured - and that the effective bit rate and depth are irrelevant at this point. And that may well be the case. Meridian are themselves bringing out new products with MQA combined with DACs that only go to 192/24 (that's as I read the specs, anyway) so presumably you have nothing to worry about with that maximum in the Bluesound.
  11. Thanks. That page was buried when I went searching for a page with a decent explanation. I've not found official instructions. This is a best guess and appears to work, as Tidal asks to use the MQA output: In the Windows control panel, choose Sound, select the Dragonfly, choose Properties, and make sure that all Enhancements are disabled and that under the Advanced tab both "Allow applications to take exclusive control of this device" and "Give exclusive mode applications priority" are both ticked. In Tidal, go to Settings, and choose Streaming. Make sure Quality is HiFI/Master, and that the Dragonfly is selected. If you get the Tidal settings wrong and an MQA device is discoverable, then Tidal will ask if you want to use the MQA device, and you can just say yes. On my machine the Settings button isn't available when you choose the Dragonfly, it just defaulted the settings to use MQA. You must, of course, update the Dragonfly with the 1.6 firmware. There's a button to start that process on the front page at www.audioquest.com.
  12. The Dragonfly's bottleneck is at the input, not the DAC. It supports only the USB audio 1.1 spec, so doesn't handle over 96/24 at the input, but the DACs used can go higher. This is why Audioquest have put the time into MQA. The Dragonflies become MQA "decoders" so you put in a rendered 96k MQA signal which it can handle, and get a higher rate signal out. If the signal is MQA encoded 384Kb, you get 384k out. Not true 384/24, because MQA doesn't do that. The initial descriptions imply that the 2L downloads at 44.1/48 aren't decoded on the Dragonfly. At the moment you need Tidal to hear decoded MQA on them, apparently. But there's no description on what is actually in the update that I can find.
  13. A bit more playing around showed that on my PC, it's exclusive mode apps that are running up the volume, not just Tidal (which needs exclusive mode anyway). I have a Dragonfly Red in the special DAC USB port on the back of my PC now, will report in more detail later. It sounds OK and so far I've found it narrows the stereo with some of my ripped flacs, and shows up some of the really bad tracks in Tidal HiFi. I'm saving MQA comparisons at the moment as I expect them to be more subtle than just the Dragonfly change.
  14. I have the same problem with Tidal in Exclusive mode on my home desktop, plus it continually defaults to 0 so I have to turn it up very carefully. It doesn't do that if it's not in exclusive mode. That's with internal sound, as well.
  15. Looks like AudioQuest have finally delivered the MQA update for the Dragonfly Black and Red. I may just drop my prejudice against the company for a little while and try one out. Is anyone here with one of these able to report? Looking at some Munich previews, it looks like Moon and Krell are also jumping on the MQA bandwagon.
