    New tube Schiit

    If they're gonna have a sophomoric name -- I'm gonna lean into it. Schiit's got a new (?) vacuum tube headphone amplifier, using an actual tube (twin triode) with actual plate voltage (100 V), actually cheap ($149). Do we know anyone who might want to test one...

    A-ha! So this is the guy! David Gleason: World Radio History

    An amazing and hyper-useful resource for us all. I hope it remains as a service in perpetuity. I've long wondered about the back story, because it is such a mammoth undertaking. https://tvnewscheck.com/business/article/david-gleason-builds-a-digital-archive-worth-honoring/...

    "PureArtFi" LS-6 loudspeaker - is this on "our" radar?

    Just saw mention and some positive feedback on this new (?) loudspeaker project, and wondering if anyone here knew of 'em and/or were paying any attention to this? I did a quick keyword search here & didn't see anything, so I figured I'd take a chance and just ask...

    HiFi bon mots (or is that bons mot?)

    There's a current thread at the Polk forums discussing a video review (by good ol' DR, in full disclosure! :facepalm:) of the 'vintage' Polk LSi9 loudspeakers. https://forum.polkaudio.com/discussion/198948/danny-at-gr-beats-up-on-the-ole-lsi9 The following comment appeared in that thread. I...

    Since Audio Research is off the market -- anyone want to buy a loudspeaker company? :)

    https://www.bizquest.com/business-for-sale/custom-speaker-manufacturer-brooklyn-new-york/BW2084589/ Ohm is for sale, it appears. Pretty reasonably priced -- about the same price as a decent house on a decent sized piece of property here in 2023. ;) I actually have a pair of Ohm Walsh 2s in...

    Another vintage "Monkey Coffin" loudspeaker reboot/update/retread: McIntosh brings back their ML-1

    Bringing you yesterday's products tomorrow seems more and more to be the default business plan for "new" loudspeakers. https://www.mcintoshlabs.com/products/speakers/ML1?utm_source=newsletter&utm_medium=email&utm_campaign=ML1announcement Some entertaining chatter about this "new" product...

    Bittersweet coda to a true rock 'n' roll (well... OK... punk) love story

    https://www.yahoo.com/entertainment/remembering-john-lydon-and-nora-forster-punks-greatest-love-story-once-i-make-the-commitment-its-forever-202649546.html Certainly a sweeter story than Sid & Nancy.

    Vintage loudspeaker musing: those boomy 1970s sealed box loudspeakers -- and a suggestion :)

    I realize that some of y'all are fortunate enough not to remember the 1970s. This thread topic may, or may not, be for you! ;) I was just reading a thread at audiokarma which contained a link to an "explanation" of sealed (and, by implication, acoustic suspension -- as opposed to other sealed...

    By request: Any appetite for/chance of a "vintage electronics measurement and discussion" section?

    So, there's been some back-corridor murmuring about vintage hifi and ASR* and, as sometimes happens, I come to this place, hat in hand, as something of a de facto spokescreature. I.e., don't kill the messenger, OK? ;) There's a moderate, persistent interest in hifi of old, even here at ASR...

    Well, well -- another cheap, weird little amplifier product from another company with a weird name.

    https://ampapa.net/products/a1 [emphasis added] Kinda makes you wonder how many carelessly designed products they've been responsible for, doesn't it? :cool: Snark aside ;) It's cute, and it's cheap, and it has tubes. And the company has a fashionably ridiculous name. I wonder if they're...

    Polk is having a significant "F&F" sale at the moment

    Not sure if it is kosher to post this here*, but I just saw this at the Polk forums and I wanted to share it somewhere. :) Polk is having a "friends & family" style sale -- Polk forum members only, it says... but that's a pretty low bar (don't ask me how I know this). Ahem. :cool: As I think...

    Class D (PWM) amplifier archaeology

    So, I'm a scientist, not a historian, but I am still fascinated by history... and I crave context. You all know that the late Sir Clive Sinclair is regarded as the purveyor of the first significant PWM amplifier products for audio. https://www.vintage-radio.net/forum/showthread.php?t=81139 A...

    So -- I see there's now a "Denafrips" loudspeaker

    https://www.vinshineaudio.com/product-page/denafrips-poseidon News to me. Of interest to any of you? I dunno. :) It's not terrifyingly expensive.

    "Playing" (or converting) SHN files?

    So... I just discovered some interesting music on an old backup portable HDD that is in the form of "SHN" files. I guess this were some sort of early lossless file format( "shorten"?). At any rate, I don't seem to have any s/w that can either convert or play them. A google search turns up...

    Saw this and thought of ASR (and others') speaker testing methodology (Altec loudspeaker content)

    Of audio, coffee, experiments, and blind testing :)

    We have a problem at our house in the wintertime with the large, aggressive songbirds known in the US as bluejays. They peck at the paint on our house. Why do they do that? I hear you ask. They're hungry (so to speak) for calcium. A couple of years ago, in an attempt (only semi-successful) to...

    Thought this was a cute project: ersatz "McIntosh" pp EL84 stereo amplifier

    Saw this... umm... Someplace Else... :p and thought it was cute/clever/interesting enough to share. YMMV, of course. https://lensprojects.com/2022/03/03/a-tube-stereo-amp-built-in-the-style-of-classic-mcintosh/

    Why did nominal loudspeaker impedance migrate from 8 to 4 ohm?

    Upon reflection, ASR seems like a good place to pose this question: Why did the world's loudspeaker manufacturers (or, perhaps, more to the point, driver manufacturers) migrate, inexorably, from 8 ohm to 4 ohm nominal impedance for their products? Is there a theoretical or practical up-side to...
