  1. Here's a video (audio only) that I made of the HomePod in the Apple store. It opens as I'm recording with cupped hands behind the earpiece mics, to screen out some of the customer/store noise, then I back off from there and remove the earphones from my ears so the sound is no longer binaural (i.e. the soundstage collapses). Unfortunately because of the store's background noise, I had to be closer to the speaker than what I would have liked, and thus much of the power and projection of the speaker's sound isn't captured well here. https://www.youtube.com/watch?v=OuOYdtW3sJ0
  2. I finally got caught up this evening on my backlog of reviews, so I ripped Disc 1 of my Silverman/Mozart Sonatas by IsoMike on SACD. I ripped the CD layer only, and converted the 16/44 WAV tracks to FLAC using Foobar2000 and the FLAC v1.3.1 codec. The compression was to 36.5 percent of the WAV size, i.e. the totals: WAV: 697115244 bytes FLAC: 254379988 bytes Since this is essentially the same type/technique/content density as the Silverman/Chopin IsoMike DSDs, and since the IsoMike folks made this SACD and its CD layer using the correct conversion software, it's clear that the compression to 23 percent that I got from the JRiver-produced WAV files is very short on 16/44 content.
  3. You get two things with the AMBEO - each worth at least $300 USD (IMHO): A very decent IEM, and a really good binaural recording system (using your Apple i-device) with microphones that capture hi-fi sound. This review has only a few sentences about the binaural recording - the bulk of the review concerns the IEM/earphones. http://www.hifiheadphones.co.uk/community/threads/sennheiser-apogee-ambeo-iem-earphone-binaural-recording-rig.4519/

  5. Here's a unique earphone with pewter earpieces. This design had me thinking (no pun intended) of Grado's porous-metal earcup housings that they use in some of their full-size headphones. The idea here is similar - to reduce resonances in the driver housings. U.S. made, the MSRP here is $179, but I don't know at this time what the international availability will be. http://www.hifiheadphones.co.uk/community/threads/thinksound-usp1-pewter-earpiece-iem-earphone-review.4518/
  6. After one week of ripping several solo piano and violin/piano SACDs (16/44 CD layer only) to WAV and FLAC -- those SACDs by the same recording company that made the original DSD files -- my FLACs ranged from 31 to 40 percent of the WAV size, or at minimum 40 percent larger than 320 kbps MP3s. The only CD where I was able to compress FLACs to MP3 size was a CD containing long silent pauses within the music, which was unlistenable in any case. I've concluded, with unexpected help from two expert sources, that the DSD to 24/88 FLAC software I purchased is either defective outright, or it intentionally embeds a stealth form of DRM into the conversions. I was not able to pursue this further outside of ripping these SACDs, because information was being withheld by persons who were offended by my questioning the validity of the conversions.
  7. I have a major DSD conversion issue, and my experience (lengthy) is described below. I think I have everything covered, with input from many experts. The key issue is some extremely suspect conversions being done with a top-rated software player and converter. http://www.hifiheadphones.co.uk/community/threads/flac-conversions-from-16-44-wav-files-are-smaller-than-mp3s.4517/
