  1. I've dealt with Andy quite a lot in the past. As you say, he's very thorough and professional. Cheers, Jason.
  2. There's a lot of things in life that can kill you. Some people are able to use common sense and manage to survive. Others need to be mollycoddled. Cheers, Jason.
  3. 60/40 Sn/Pb solder is still readily and widely available. Jaycar, RS, E14, Altronics, anywhere really. Cheers, Jason.
  4. It isn't that they're trying to rip you off, the tweeters in coaxial drivers are generally not replaceable (some are, most are not). When you buy speakers with coaxial drivers, you've got to expect have to replace the whole drive unit. As for availability, try overseas. The Kef importer to Australia changed in 2013 IIRC, and as part of the deal (as is often the case) the old importer had to destroy all of the spare parts they held in stock. Cheers, Jason.
  5. I reckon it's just deterioration over time Felix. I think these issues will become more prevalent with the use of cheap rubbish solders coming out of China. Always use the best solder you can find! Cheers, Jason.
  6. Very sad to lose such a great talent. The first time I saw the Rifles was Christmas eve 1985, when I was 17,, at ‘Evil’ in the Evening Star Hotel in Surry Hills, what a top night, with their last song being ‘We Wish You A Merry Christmas’. Jason.
  7. A good Sydney band from the late 70's - early 80's. Jimmy And The Boys - Not Like Everybody Else Cheers, Jason.
  8. A nice topic and great posts, thanks. I'm not trying to bust your theory, far from it, just a couple of points that might be worth discussion: 1.) Reducing the wire diameter to try to force the skin effect is interesting. The skin depth in Silver at 1kHz is only 0.002mm, so you'd have to be using inordinately small wire to make any meaningful change, and by that stage I suspect the current handling capacity of the wire could become a point to consider. 2.) Couldn't the drain wire (singly connected earth) feed the noise signal back via the common connection, with some frequencies in phase, some out of phase into the doubly connected earth? Therefore being both a help and a hindrance? Regards, Jason.
  9. How about the Sigma Turbo from about 1980? Or maybe various Saab 900's? Back at that time, the term supercharger included turbos, which was a turbosupercharger. Cheers, Jason.
  10. @Bunno77, There's a bit, and from my olde worlde spinning USB HDD. The dodgy phone noise-o-meter on my phone says 34 db. I guess in the dead of night you'll hear it, but if there's music playing, you won't. Cheers, Jason.
  11. I've just put together what I reckon is a ridiculously cheap way of having a very good sound quality streaming system, with storage, and library management, spending very little indeed. The system consists of an Intel NUC running Roon ROCK (dedicated Roon Core), a USB HDD for storage, and a USB audio device for headphone playback. The NUC is an old DN2820FYK, which is a Celeron machine. Roon says that this level of hardware won't run Roon. It does, with no problem at all. To the bare NUC I added 8Gb of RAM, and a 32Gb SSD. Roon ROCK is very small, so the 32Gb SSD still has 25Gb available for the Roon database. My 500 album library takes up 2% of this. so there's room for over 20,000 albums in the database. The 500Gb HDD has room for about 2,500 albums in FLAC format. Plus you can have all the streaming service albums as well. The audio device is an Audioquest Dragonfly Black, which has the ability to output full MQA. The ROCK can perform the first MQA unfold, and the Dragonfly does the rendering. Now, as this is not meant to work, I just gave it a bit of a stress test to see if it would fall over. With the NUC sitting there running Roon ROCK, I plugged in the Audioquest Dragonfly Black. There were some flickering lights, then the Dragonfly popped up as an output device on the Core. I selected it, and set it up to be an MQA renderer with the Core doing the first MQA unfold. This worked fine, with the purple light on the Dragonfly coming on when playing MQA material via the Tidal. All sounded fab through the headphones plugged in to the Dragonfly. I then enabled two DSP functions, Crossfeed, and Parametric EQ, and played with the EQ, with three bands modified. No stuttering, no problem browsing. No issues at all. At the moment, this low level of hardware seems to run Roon very nicely. This system cost me about $250 as I used mostly second hand bits, but if you just bought the NUC second hand, and the rest new, it would be: If I price it out: $200 2nd hand NUC with RAM and SSD (you can get i3 and occasionally i5 NUCs for this price, which would be even better) $69 1 Tb USB HDD $139 Dragonfly Black Total: $408 for a complete Roon system with storage for 5000 albums, complete with MQA playback. Not bad. A high end audio company would wrap this in a fancy looking box and sell it for $10k plus. Here's the complete system, just bring your headphones and subscriptions. And here is the browser running on the PC, and the iPad. Cheers, Jason.
  12. Thanks @Whites On page 40 of the 70 page insurance contract, it says that bikes are only covered for up to $2,000 in total, no matter how many are stolen. Minus the $250 excess. That means $1,750 all up. Lucky we're on the 'Premium' insurance, otherwise it would have been something like $200 all up! Cheers, Jason.
  13. I'm devastated. Both of my beautiful bikes posted above were stolen this morning from our garage locker in Kingston ACT. UPDATE: Luckily we found the Devinci where the thief had left it where he stole someone else's electric bike. Now just my lovely new Santa Cruz is missing. 2019 Santa Cruz Bronson CC X01 If anyone sees this reasonably rare bike around, please let me know. It has distinguishing features that I won't relate here. A word of warning. Don't think that your home contents insurance will cover your bikes. We'll only be getting about 10% of the value of these bikes back. Thanks, Jason.
  14. I'm sure you are trying to help, but your reply means nothing. I know they match the Onkyo cart, that's what I said in my original post. What I want to know is if there are any other carts it fits. The list so far: Audio Technical AT-UL3 Onkyo DN-64MCE Cheers, Jason.
  15. Hi All, I have a bunch of ATN-UL3 stylii for the AT-UL3 MC cart, but don't have the cart itself. I'm wondering which other carts this stylus might fit. I know it fits the Onkyo DN-64MCE, which I have. This Onkyo cart is not the same as the AT-UL3 cart. Is there a compatibility list or similar? I've not been able to find anything. Many Thanks, Jason.
