Pardon me, but your response looks like you're actually trying to justify their offerings. That would definitely change my assessment of this forum (i.e., if there are any discounts or representations of manufacturers' products not disclosed openly by admins and moderators)...to be honest...

Kaleidescape prices look to be ~10x higher than just ripping via makeMKV to general purpose external USB HDs. I think printing the volume directories of each external HD (assuming you have five to ten 4-terabyte HDs) and using those printouts like a card catalog is much more cost effective (I...

Storing a BD movie costs about $1 in external HD storage costs (and you can use the external HD for other storage needs, too.) A DVD costs about 1/3 that amount, and 4K UHD cost about $2 per movie (i.e., 2x larger movie files). In terms of monthly streaming costs from Netflix or Prime (etc.)...

This is one reason why I rip all my video discs to external USB drives using makeMKV, If you want to do 4K UHD discs, that requires something called a LibreDrive (a re-flashed Pioneer disc drive) to eliminate DRM, etc. (also available through links found at the makeMKV site). I had noticed my...

Referencing a previous post on another forum: I just noticed the news this AM: Technicolor Begins To Shut Down Operations I believe that most brands of photographic films have been discontinued by their manufacturers of late. Die-hard "analog-only" directors and cinematographers (e.g., Chris...

I just got a "ublock origin" warning about using the weekly emailed link to this thread. I don't plan on using those emailed links or reading more about this subject. Just FYI. Chris

FYI (only)... Here is an uncalibrated RTA (real-time analyzer) measurement taken in my listening room about 10 years ago, showing local peaks due to in-room laptop and HVAC/refrigerator noise sources. I'm aware that the 90 Hz and 197 Hz peaks came from the nearfield laptop that I was using...

Likely an HVAC fan. I've seen this often in released music tracks that I've demastered. In North America (60 Hz/110v), I noticed that this fundamental frequency is usually ~17 Hz and its harmonics (34, 51, 68 Hz, etc.). The EU will be 14 Hz, etc. If the HVAC system was on, try temporarily...

Most recently I upgraded to 77" OLED and 4K/UHD...without of course realizing that ~95% of recent big budget movies made over the past decade or so shot in native 4K digital format are of the "comic book hero" genre. So I've recently been scouring online sites for movies shot in native 4K...

See Some Attributes of Linear-Phase Loudspeakers. The above document is found at the Linkwitz Lab site. It's kind of a smorgasbord of references on the subject of minimizing phase growth in loudspeaker acoustic output. It isn't rigorous, but it is thought provoking. The first derivative of...

[EDIT (11/3/2024): When I started on my current setup in 2007, I had already spent 25 years with a pair of Magnapan MG-IIIa's and some Carver electronics (acquired in 1984). After raising a family and getting them educated, I started looking around for "the next thing". I wasn't too thrilled...

In this case, do not use "Estimate IR Delay", since it will move the peak of the impulse response several milliseconds to the right (in this particular case, only) and then you'll get a phase response curve that's miles long (in the vertical direction) in the plot window. When I bring up the...

Within REW, that's the "SPL & Phase" plot, with dark background (preferences: preferences:view:colour scheme-dark), then: graph: 1/12 smoothing, actions:generate minimum phase..., actions:unwrap phase. The scale limits are set appropriately within the field of the plot by the pop-up zoom...

Note that drop-off in amplitude response above 10 kHz. I'd set the microphone vertical position to be centered on the high frequency driver centerline to see if that downward slope in amplitude response is real. It looks like you took a measurement with the microphone off-axis to the highest...

Here is a transfer function plot from your REW measurement file showing the amplitude and phase responses in-room as measured by the microphone. Note the flatness of the minimum-phase response and the extreme cycling of the excess phase response. This says that you've potentially got very good...
