    Beautiful Desktop Tube Rig of Japanese Lady Audiophile

    Several videos of Japanese audiophilia have been making their rounds on audio forums, but my Youtube recommendations recently surfaced this new video of a Japanese lady audiophile introducing her vintage setup. Incomplete subtitles, but Youtube closed captions + translation does a decent job...

    Voice Coil Offset for Midrange Inductance Linearisation - Dan Wiggins (Adire Audio/XBL)

    One of my favourite pieces of writing in audio, ever, was by Dan Wiggins (of Adire Audio/XBL^2 dual voice coil driver design fame). It is educational, original, and yet quite accessible. In it, he robustly justifies an offset voice coil (as measured on a Klippel driver test rig) for a wideband...

    Port Resonance Suppression: Inspiration from Technics

    You may have seen the measurements I posted here of the Technics SB-C700, a coaxial 2-way standmount. Despite being an innovative design with superior measurements to the LS50 (especially wrt directivity <7kHz, bass SPL and extension) for not much more cost, its market prospects were torpedoed...

    KS Digital Residence 505 (3-way DSP active with coaxial MF/HF and linear phase)

    KS Digital, a small German pro audio brand just released their first line of home audio actives. They do DSP actives with FIR phase linearisation, with manufacturing in Germany. They now have a 3-way floorstander with a SEAS Prestige coax (just about the best-measuring off-the-shelf coax... but...

    Broader Considerations and Limits of Harman Headphone/IEM Curves

    I was asked to write a three-part article series on the Harman headphone/IEM curves by an up-and-rising headphone blog. Being acutely aware that I could never measure up to existing articles about the curves and their experimental derivation from luminaries such as Sean Olive and Tyll Hertsens...

    Subtracting FRD curves in REW/VituixCAD

    So some of you might know I have a pair of SEAS Idunns that had a modified baffle (crucially the same CtC). I got VituixCAD-simmed diffraction of the stock baffle and the modified baffle. I want to subtract both curves to see the difference between the original baffle diffraction and the new...

    Speaker Measurement Shipping Bounty

    I threw out this idea off-handedly in an earlier post of mine, I believe in the KH80 thread when it emerged that Klippel has an open day in March for measurements. But I really have some speakers I'm interested in seeing measurements of - interested enough that I'm willing to pay (within reason)...

    Austrian Audio Headphones - Spiritual Successor to AKG

    After the acquisition of Harman by Samsung, much of the AKG Vienna team split off to launch their own company, Austrian Audio to manufacture microphones and headphones. I find this a more exciting release than the megabuck headphones from MySphere and RAAL recently, because they claim to have a...

    UK Travel Recommendations (audio and non-audio)

    I'll be based somewhere in the Midlands (probably the Coventry area) for the first few months of next year, but can travel throughout the UK. Does anyone have any recommendations, especially insider recommendations off most mainstream lists? I'm into craft stuff (especially leathercraft...

    FS: Modified SEAS Idunn - South-East Asia

    A long shot (especially since I'm not sure how many members are even near enough to pick it up), but my integrated amp shit the bed and I thought I'd take the chance to overhaul the entire setup, including my modified SEAS Idunn with the wonderful DXT tweeter. The crossover follows SEAS specs...

    Comprehensive turntable measurements by Hi-Fi News

    Occasionally I browse hi-fi magazines with measurements at the local Kinokuniya. Hi-Fi News from the UK (now part of the same parent company as Stereophile) does less comprehensive speaker, amp and DAC measurements compared to JA at Stereophile, but does comprehensive measurements for turntables...

    Spinorama Measurements of the Apple Homepod

    Sausalito Audio Works - an acoustics research consultancy that has worked with Audi and B&O (you might have seen their audio lenses on the Audi A8 or the Beolab 5) - recently released Spinorama charts of the Homepod. Performs just as one might expect an omni array to measure, with sidelobes...

    Looking for cheap, well-engineered streamer-DAC-preamp recommendations for XLR-input active monitors

    I intend to switch my current passives out for active monitors. I'd also like my rest of the digital setup to keep up with the progress (not in sound, but in amenities). I have a pretty clear idea of what I'm looking for: a wi-fi streamer (capable of handling common services like Spotify and...

    An impeccable source of loudspeaker measurements for dirt cheap

    Perhaps channelling German stereotypes, German pro audio magazine Sound and Recording has the best loudspeaker measurement regime I have ever seen. Audio engineer Prof. Dr.-Ing. Anselm Goertz takes demanding anechoic measurements from 4m at an acoustics lab. Their measurements include...

    Better late than never

    Hi all and Amir especially. Thought I'd just introduce myself here and begin posting. I'm a frequent browser of the site and an advocate of evidence-based audio reproduction (I detest the label "objectivist" for its confusing similarity with Ayn Rand and the relative vagueness of the term). I...
