RIP someone or another
Wow. Back in the day he and Khrushchev were responsible for the world coming within a hair's breadth of nuclear Armageddon. Love him or hate him, he certainly left his mark on history writ large. RIP.

The Headcase Stax thread
{pet rant mode} = on It was summed up by my boss years ago; in earlier days he was a racing driver, and he used to describe such people as "all dust and wheelspin, but no forward traction". The world is full of them - bullshit merchants with the appearance of glossy form, but no substance at all. Grinds my gears. {pet rant mode} = off

Downsizing Speaker Setup
That is the only problem with the LX-Mini, it absolutely looks like a drain pipe and rubber coupler. The trick is disguising it to look less like what it is made from http://www.linkwitzlab.com/LXmini/Gallery.htm

Downsizing Speaker Setup
It really shows how many outrageous speakers I've subjected my wife to over the years that she thinks the LX521 is a distinct improvement on what has gone before! Maggies, Martin-Logans, Podium 1; Quad ESL57. So yes - I can see where she's coming from!

Downsizing Speaker Setup
It may seem perverse to consider building something, but these http://www.linkwitzlab.com/LXmini/Introduction.htm take a lot of beating, and can be built for not much more than $700 for drivers and all hardware, and including the DSP crossover. And you need four channels of amplification, which of course costs some more. Such as https://emotiva.com/products/amplifiers/xpa-gen3 for about $1k, but there are many options. You can get a kit from Madisound https://www.madisoundspeakerstore.com/2-way-speaker-kits/lxmini-linkwitz-lab-speaker-kit-pair/ for a number of kit options. Someone who had built a pair came along and we did a shoot out between the LX-mini and my LX-521. Apart from a comparative lack of bass, the imaging and neutrality were just as good.

Farage is a dangerous fucker. And his involvement with Trump underlines that in spades. He has cultivated a cheeky chappy, beer drinking, man of the common people persona as head of UKIP (the UK Independence Party). But scrape the surface and you find that he made his money out of being a commondities broker. So not so much a man of the common people really. But, considering that UKIP have one single MP (out of 650), he commands a wholly disproportionate level of publicity.

Three days after the Grinning Man, we went to the (London) Old Vic last night to see Glenda Jackson as King Lear. There are actually two productions of King Lear in London at the moment, one with Jackson and one with Anthony Sher. The Jackson one was the real deal - with Celia Imrie as Goneril, Jane Horrox as Regan and Rhys Ifans (he was Spike in Notting Hill) as the Fool. It was uncut, starting at 7pm and ending at 10:30pm. Jackson has returned to the stage aged 80 after 23 years in politics as a Member of Parliament (Labour party). Another standing ovation. Absolutely stunning; a review here https://www.theguardian.com/stage/2016/nov/05/king-lear-review-glenda-jackson-old-vic .

Went to see The Grinning Man, a dark new musical based on a Victor Hugo's book The Man Who Laughs. This is at a small theatre called the Bristol Old Vic, the theatre that has been open the longest in the UK, opening its doors in 1766. The director of The Grinning Man is the same guy who directed War Horse It was bewilderingly good - I am still reeling at the whole experience. It was the last night - and it has only been running for one month. But that will not be the end for a production that was several years from first concept to the stage. I would say it was certainly destined for the West End, and for Broadway - For me it had more impact than Les Miserables, and deserves real success. A standing ovation, and tears shed by the audience, and oddly by the cast - although that was probably final night blues. There was a silent movie made of the book in 1928, and the story of facial disfigurement was the inspiration for The Joker. http://www.bristololdvic.org.uk/grinningman.html- Do you hear what I hear?

The definitive version, from the concert tour we saw. It has just reduced me to tears- Do you hear what I hear?
For me the thing that was causing a phasey sound in the bass was the chimney above the fireplace. That gave an organ pipe resonance at 30Hz and harmonics (60, 120 etc Hz). Cured it by stuffing the chimney with a load of old clothes that I'd been storing up for gardening etc in. I was keen on using Monster Traps on the rear wall http://gikacoustics.co.uk/product/gik-acoustics-monster-bass-trap-flexrange-technology/ which were very affordable. Unfortunately the WAF actually went negative, something I did not think was possible. That was very much a one sided discussion- AOIP (Audio over Ethernet) or is USB dead?
Excellent links, Grahame.- RIP someone or another
What a truly rotten 24 hours. Leonard Cohen, Victor Bailey and now Robert Vaughn.- RIP someone or another
^This. RIP, far too early. Here, in full flight in solo bass of what has become the jazz standard Birdland https://www.youtube.com/watch?v=q9UCBsXI4LI- Do you hear what I hear?
I have not, but have heard they can work well - the microphone in a smartphone seems to be of very high quality with a rather flat frequency response. I'd have to poke around on the web to substantiate that, but recall I've seen this written down. But I bought my XTZ unit a decade ago before smartphones were the palm sized high grade computers they now are. If I were doing measurements starting right now I would certainly research what the capabilities of my phone were and what were the best apps.- What are you listening to Part the Third
The two disc 180g vinyl of Famous Blue Raincoat (20th Anniversary limited edition) has some tracks that are not on the CD. Which came as a pleasant surprise when I played it. In the liner notes is a copy of a letter she sent to Cohen in 1956, when she was 9, about Song For Berndette. And also Cohen's reply. Just shows how a kind reply can have lifelong musical repercussions. Just tried to find a price for these - of course no longer a current pressing, and which now changes hands for $2000. Holy carp. - Hifiman Shangri-La, new Electrostatic
