The Naim Statement. About the same price as the boulder above, but at least you get a preamp (the middle slice).

Ooh - shiny

He doesn't say what the measurement bandwidth was. Which really makes it a very loose specification. The only hint is the very sharp mains harmonics in the noise plot, which are way sub-Hz in width. To get to -158dBV (-155.8dBu) from -107dBu on a 20kHz B/W you would need a measurement bandwidth of 0.25Hz, Shockingly badly specified.

The most significant issue with the THAT 1200 series of receivers is noise, -107dBu. It is dominated by the rather large values of noise-generating resistors inside (7k typical). With a good discrete design, or clever use of opamps you can get to -120dBu, which challenges measurement (<1uV in a 20kHz bandwidth).

Cooler is a relative term with the T2 Clone

I have mine on two separate shelves - in a stack it gets pretty toasty!

Have a spiffing day!

Have a truly superb day!

Have a great day, sir!

I had absolutely no idea that Robin Williams was such a keen cyclist.

Thanks mate - will download and have a look. The Ayre stuff is pretty awesome.

I have that on CD (well, now ripped to the NAS too). Great album.

I thought I had a basic grasp of the tourbillon, until I chanced on a 3-axis version. Just a pity the cages look so roughly finished.

I'll probably configure it single ended first. The two small boards can be bal2unbal or unbal2bal. So for SE these would be unbal2bal. Then rewire tonearm in a way I have not entirely thought through yet and go balanced input to balanced output. Then the small boards would be bal2unbal just to provide an unbal output if needed. Casework will come from here http://www.modushop.biz/site/ , at which point I will be financially punished as a result of the stupidly weak pound (globally) as a result of the clowns who voted us out of Europe.

Just put it on my favourites list on Tidal HiFi - will listen to later. Useless factoid number 37a: Mark Knopfler bought his first guitar from the shop I worked in on a Saturday aged 16 http://www.jgwindows.com/about-us .

Happy birthday!

OK - completed and part tested current input balanced phono stage by Borbeli (and Sigurd Ruschovski). Better sound good - cheap to build it was not. Need the casework and build three more shunt regulators (the thing with the black heatsink). For use with Garrard 401/SME/DL103(Zu Audio rebuild)

I'm not on Amazon Prime. Yet!

Strange Angels. In her earlier stuff it was either speech or vocoder. For Strange Angels she had to go to singing lessons. On other topics: The Ring. Saw the whole thing live three years ago here https://lfo.org.uk/ . Each part was separated by a day, so the whole thing fitted into a week. Awesome. My wife is not a Wagner fan, but she was in tears at various points, and latched on to the massive story arc of the whole cycle. And if you like Gould, and a very strange guy he was too, buy the boxed set of everything he ever did. 40 CD's. It is particularly interesting to compare his two recordings of the Goldberg Variations, one as a young man and one a year before his untimely death at the age of 50. They are very, very different. In all his recordings you have to ignore his grunting though.

I'm a real fan of Anderson, but I don't have that. I was frankly amazed that she is now 69. Where have the decades gone?

^This. The national news in the UK is reporting many people abandoning their homes and heading out of the storm's path.

Looking at the spec for the Rigol, you have a choice of 50MHz or a bandwidth limit of 20MHz. Since the noise voltage goes as the square root of the bandwidth, and assuming you have selected 20MHz bandwidth the noise voltage you measure will be 32 times higher than you would get for a 20kHz audio bandwidth. A-weighting applies a correction for the way the ear's sensitivity changes with frequency for quiet sounds.

Yes I can do that. They key is to measure over that audio bandwidth and the A-weight it. I'll give that a bash tomorrow.
