    Rush fans

    And it's a song by Rush, in case the context is missed:): https://en.wikipedia.org/wiki/Lakeside_Park_(song) Thanks for asking, one of life's deep questions. Next up is where is "Closer to the Heart?";)

    Wharfedale Diamond 12.1 Review (Speaker)

    Any of those will do. I would get the Jantzen because it is cheap! These resistors are one of the simplest components ever, just a long length of high-resistance wire wrapped around an insulator. Mundorf is no better, it should not be a struggle to make such a simple thing cost-effectively...

    Replacing The Manufacture’s Jumper Bar

    No, that length of wire has no audible impact. You are falling for the oldest trick in the HiFI book. Try an actual resistor. That will actually reduce the treble output. Like this...

    Rolls SX45 Review (Analog Crossover)

    It certainly won't affect or fix the channel imbalance that was measured on the tested unit. The basic performance of each channel alone is decent. The problem is the integrated product, not the ingredients.

    Rolls SX45 Review (Analog Crossover)

    It's in the manual: https://www.parts-express.com/pedocs/manuals/245-1184-rolls-sx45-manual.pdf https://www.ti.com/product/RC4560 Does the op amp matter?

    Help fixing upper bass nulls, rear test panel didn't change much

    Nice room and setup. I assume the speakers and the mic didn't change position one bit between the measurements. The lower bass nulls are likely room modes. The nulls and peaks above 200Hz are likely comb filtering, like illustrated below: https://www.genelec.com/monitor-placement If so, the...

    Jbl 4329 teardown

    I have not seen the insides of the 4329, but have on other models. These hidden fastener lenses are typically mounted from the inside of the cabinet, access is with the woofer removed. If experience with JBL's larger speakers holds, the clearance is tight. I have some pictures of the M2 lens...

    Why the hate for Grado?

    They have mixed bag of measurements. https://www.rtings.com/headphones/reviews/grado/sr80e-sr80#test_321 I don't care for the sound, and even less for the fit and feel. Otherwise it seems they could be EQ'ed to my liking. But some like the design, and for sure everybody's fit and tolerance for...

    Speakers deconstructed

    Great question. https://www.monitoraudio.com/en/hyphn/uncompromising-performance/ They have a few exploded views. Plus images of handcraftiness: A history in photographs of the design phase of the project: A creation video, and an exploded woofer animation. The even featured the likeness...

    RME DPS-2 Linear Power Supply

    Yeah, I saw it in my inbox when I woke up this AM, right above the email titled "Bloodied Horses Gallop Through Central London", figured everybody was having an off day.;)

    Will Belden 1696A work with my headphones ?

    Aside from having a foil shield which is tightly wrapped around the center conductors, it has a very stiff jacket with an additionally stiff ground wire. So not what I think was suggested. The stiffness of the package would make for an uncomfortable listening experience. And be subject to all...

    Are passive radiator monitors true superior to ported, or are there any cons?

    Those are (IMHO) very good budget speakers. The passive radiators do provide bass extension that most speakers at this price point can't match. Polk has been doing passive radiators since ages ago. It's an achievement just getting a floor stander with two passives at this price that sounds...

    How Long Do Speakers Sound as They Were Designed ?

    Measure. I tend to measure my speakers out of the box. I may be odd that way. I used to work sales and installation, so it is a habit based on the surprising number of defective components companies sell us. It also allows me to monitor degradation. For instance, your tweeters have...

    Legal fund for Reviewers/Erin?

    So it's narrowed down to: Sample to sample variation from Tekton. Irreproducibility of impedance measurements, likely on Tekton's side. Online emotions. All of the above.
