    Perhaps this could be the key to an accurate measurement.

    REW Measurements of AlleyCat's Room- Take 2

    There is no misunderstanding from my side. I just don't share your assumptions or those of Erin. Meta-reflection by the scientists about their own assumptions is, in my view, part of the scientific process. Extrapolating from anechoic or quasi-anechoic measurements to the real-world rooms of...

    REW Measurements of AlleyCat's Room- Take 2

    I agree, and therein lies the risk of interpreting the Klippel results in an absolute manner(as it is often done) Ok, I understand and therefore, there is no relevance to the graphs previously shared. It is your room and your user case N=1 I was indicating that low and high frequencies...

    REW Measurements of AlleyCat's Room- Take 2

    Klippel is one of the most powerful tools we have available (but it is not perfect). It uses near-field measurements and then extrapolates a prediction of the far-field response( I am not sure that the Tool graphs are derived from a Klippel, but I guess it is based on the same mathematics...

    REW Measurements of AlleyCat's Room- Take 2

    Erin's views are based on his work with Klippel. In the real world, the results might look different than the mathematical assumptions on which the Klippel predictions are based. Have a look at these graphs from an article by Tool. https://www.linkwitzlab.com/Toole-Room%20calibration.pdf It is...

    The 2024 Global hifi show calendar

    A perspective from Stockholm, Feb 2024. High-end Mässän 2024 was held in Stockholm 17-18 Feb, but not in City’s Sheraton hotel, which for years served as the main venue for the fair, but the Klara Konferens & Happynings Conference Center at Klarabergsviadukten 90, right next to the main railway...

    @AlleyCat why not, as a start, try a software solution such as Roon or a plugin to at least experiment with EQ if you stream or play ripped music?

    The 2024 Global hifi show calendar

    Axpona 2024 seems to have been a feast both for the ears and the eyes. Hopefully, some of the products on show will make their way over to SA as well. Some very interesting designs. https://www.hifipig.com/axpona-2024-report-part-1/ https://www.hifipig.com/axpona-2024-report-part-2/

    FS -DACs Fezz Buzz- An Early Bird offer on the Lampizator designed Equinox

    The Equinox DC is winning friends not only for its slick design but, more importantly, for its sound. "The Equinox is a fantastic sounding machine. It's not clinical, and at no time does it get harsh. Even on INXS some of their tracks can get too much. Vocals excel with the Fezz, listening to...

    REW Measurements of AlleyCat's Room

    The measured result is a function of both the speaker and room, plus the interaction. We should perhaps be careful not to isolate one of the components and attribute the in-room response measurement to it, i.e. the room. Could this not be part of the explanation of the measured results as well?

    QUICK REVIEW: Pathos Aurium Headphone Amplifier

    It's always good to get an excellent press cover, especially for products that do have a strategic price tag. "Before heading down to the lower level I revisited the ASONA room to listen to the new Dan Clark E3 closed-back headphones driven by a Pathos headphone amp. It was a very impressive...

    FdlSys - Sad news

    I am still shocked by the news, and it has been twirling in my mind just how sad it is and what a loss it must be for his family and loved ones, considering how he touched so many of us with his knowledge, attitude, and character. I last met up with Mike before I left Jhb last year, and as so...

    on-line scam

    That's on point. SARS and Customs are becoming more intent on closing loopholes. The APN process, which was activated in December 2023, is a mechanism to ensure VAT and Duties are paid.

    Listening Level (dB and Room size)

    This is another key to unlocking the topic under the discussion- Fletcher and Munson/ISO226(2003) "Arguably the main takeaway here is that our perception of tonal balance is dependent on the sound pressure level at which we are listening. In other words, how we set our monitor gain can...

    Listening Level (dB and Room size)

    I was at church on Friday with apparently the biggest pipe organ in SA, and the organist really ripped loose from time to time. I checked with my phone during one song, and the peaks were just touching 90dB where we were sitting, and the average, which was relatively loud, was around 75dB to 80 dB.
