  1. That's interesting. Not having anything like the level of technical understanding of the digital audio capture and replay process, I'm not in a position to confirm or refute any of the article, but I found the language used was usefully understandable. I did want to question one thing though, as I may have misunderstood one of the few things I thought I did know about digital audio! One paragraph talked about the Nyquist Theorem, and says: In particular, the Nyquist Theorem revealed that a human ear, whose upper frequency seems to be capped at 20,000 Hz, could not possibly use signals sampled above 40,000 Hz. (This is why CDs and WAV files sample at 44 kHz, slightly beyond that limit). The fact that individual human ears can’t hear above that range — while bats can — is the warrant behind the claim that a sample rate up to 88kHz is useless unless you’re a bat. The paragraph seems to be talking across two different things here. I thought that the sampling frequency of 44.1KHz (or whatever) described the number of samples taken in a given time period (second) and was nothing to do with the frequency range captured. In other words, there are 44,100 samples taken each second of whatever frequencies are present in the source signal, whether that's 1Hz or 100KHz. Have I got that wrong? Is there a relationship between the sampling frequency and some sort of upper limit of what can be captured? I'd be grateful for some clarification. Jules
  2. Fully working, complete with fully functioning remote, and instruction manual. Also comes with original power lead. Slight scratch to front top of unit on right hand side (see photo). Unit has been used and well looked after all its life. Nothing wrong with it, but upgrade of kit forces sale. Looking for £40 but open to sensible offers. No box sadly so really this is collection only from Andover or Southampton, or can deliver within a reasonable radius for a cup of tea and a sticky bun!
  3. First play through (been in my "to play" pile for probably 2 years)
  4. Well that sounds intriguing... I have no problem climbing ladders. Worried about "extras" though...
  5. Gutted I couldn't make it after all, I missed out on all those fish fingers! Sounds like another very successful BO John, I shall look forward to hearing your refurbished 989's in full swing at the next one, hopefully. My weekend was spent doing slightly less exciting things.... laying out wiring for our new driveway lights...
  6. John, so sorry for the late notice but I'm not going to be able to make your bake-off tomorrow after all. We are having our driveway and front garden remodelled and it's taking longer than expected so far and the project is behind schedule. I need to lay the conduit and cabling for all the lighting and sensors this weekend ready for the concreting to be done next week, not the nicest of jobs but hey-ho, got to be done. Thought you might like to know in case you have a "reserve"list of attendees. Hopefully catch you at the next one. Jules
  7. Nothing like competition to drive down costs. Let's hope it doesn't also drive down quality of service (I don't mean the files, I mean the reliability, range, etc)
  8. https://www.whathifi.com/news/qobuz-says-no-to-mp3 Not being someone who subscribes to any online services, but I'd say it's a good move. Not before time, either!
  9. I really like that Hyundai - not necessarily from an aesthetic perspective. It's inoffensive but not exactly pretty. Mind you, I drive an i3 which is, er, challenging to look at so who am I to complain? I love the technology, and would have one tomorrow IF there were any refuelling infrastructure locally, and it didn't cost £70k. In two years time when I'm due to swap my i3 I'm hoping things will be a lot more advanced than they are now. If they are I would definitely consider making the swap to Hydrogen. One thing is for definite - I would never go back to a conventional petrol or diesel car for normal everyday use. They just feel exactly what they are - old technology. Worst case would be another BEV, which again will no doubt be more advanced than the current crop of models. The idea of powering your entire life on Hydrogen is very attractive, as long as (to David's point), the gas is created exclusively by the use of renewable energy, otherwise you negate the environmental advantages. And I agree it's probably a far better bet for effectively storing the energy generated by wind and solar to even out the peaks and troughs in demand. As long as there's enough Hydrogen atoms in the world to allow us to do that, and not cause a deficit in some other vital chemical!
  10. Thanks Tom, now that makes a bit more sense. On the first picture I thought they were about 30cm away form the rear wall! Out of interest do you have solid floors or suspended? I have seen one pair of C500's in the same finish as yours advertised for sale, but I'm hanging out for either the all-white or the white / oak finish. That said yours do look gorgeous. I'm making a pre-shortlist of speakers as potential upgrades from the C40's, from which I'll hopefully whittle down to no more than three pairs to audition. Naturally the C500's are straight through to the final shortlist (biased? Moi? Sacre bleu....)
  11. That's really interesting, and points to a much, much cleaner future than we currently have. And does beg the question, with all these advantages why is it taking so long to get this stuff to market? I'm assuming the answer probably involves oil companies, governments and self-interests... 360 miles is a decent enough range I would say. Well done Honda for having the balls to put this into production (shame about the way it looks, though). I'm fully on-board with this future. It's exciting. Whatever way things turn out, I think the one thing we can guarantee is that it's going to be very different to the present. And as soon as a car manufacturer is brave enough to make a massive hydrogen SUV I'll be at the front of the queue to replace my diesel one that's for certain!
  12. If you like the KEF sound you currently have, but just need a bit more of it, could you accommodate a larger pair of Qs? You don't say if you have any particular space restrictions except for the close-to-wall placement. I'd probably consider either a sealed-enclosure or a design with a front port like your current ones, rather than a rear port, given that placement. Not sure how the overall sonic signature changed but the larger Q90s were pretty capable in the bass department (my dad had a pair before the ceiling in his music room came down and trashed them - he replaced them with Castle Howard S2s). There's no Q90s on Fleabay at the moment except a damaged pair, but I shouldn't imagine they'd go for more than a couple of hundred tops, given the price of smaller models for sale there at the moment. Actually, thinking about it a pair of Castles might do the job nicely - transmission-line design gives an extended but controlled bass, and depending on which model you go for, you could actually choose something that's voiced to your preference as there were quite big differences over the years. My Series 1 Harlechs were great but quite forward sounding, whereas the Conway 3s I tried after with the carbon-coned drivers had a much darker presentation. There's a whole variety of models on Fleabay, Severn, Avon, Kendal, Pembroke, plus the standmount models like the Trent, up to about £300 tops by the look of it. Beautifully made and finished too, just watch out for any model using the translucent plastic-coned drivers as the cone can detatch from the surround and warp, giving a nasty rasping sound (as I found to my cost on my Harlechs - I'd have flogged you mine if they didn't have the knackered drivers!). I don't think you can get hold of replacement drivers any more, I tried. Have fun in your search, and get along to as many bake-offs as you can to listen to different sounds and be coerced into spending far more than you really want to Jules
  13. I absolutely love this. I currently drive 2 cars and they could barely be more different - one is a 4.0L diesel 7-seat SUV, but this gets used ONLY when I have a need for a big car to either move stuff, or move people. It's absolutely not a daily driver under any circumstances, sometimes it can sit on my drive for a week without turning a wheel, and then get called into action at the weekend for doing, well, weekend stuff The vast majority of my mileage is done in a BMW i3 BEV, which I absolutely love. It's not perfect, no car is, but on overall balance it's a superb bit of engineering that's a capable, reliable, refined vehicle that's both fun to drive and helping me do my bit for local emissions. But it's true that while the car suits my needs down to the ground, there will always be people for whom a (realistic) range of 100 (winter) to 160 (summer) miles between charges just isn't going to work, and of course also those for whom the simple practice of recharging is actually anything but simple due to the logistics of their living arrangements. I see hydrogen fuel cell vehicles as an answer to those situations that don't suit a BEV. Refuelling shouldn't be any more complicated than refuelling an LPG car I shouldn't think, and take about the same time give or take, which eliminates one of the main drawbacks of cars powered by battery (even the most recent models with 150kW charging capability) - time. For a lot of the time there's an answer to the time-consuming "fuel stop", which is to do it little and often. Everywhere you go, plug in and trickle charge - the supermarket (PodPoint and Tesco are currently rolling out chargers at every superstore and Extra), in public car parks, at work, at the gym, but of course that requires an installed base of public charge points that's an order of magnitude greater than we have at present. There simply isn't the current infrastructure to support mass adoption of BEVs, as I've discovered on a couple of occasions that nearly left me stranded. In principle every current fuelling station could supply hydrogen, and as mentioned in earlier posts there's the rather exciting prospect of having your own generation plant at home for the ultimate in convenience. So looking at one of the main points of resistance concerning adoption of electrically-propelled cars, that one should be covered well. The second issue is the question of range. I stand to be corrected here but as far as I'm aware, the last reviews / test I read of a Hydrogen fuel cell (HFC) in a magazine (Toyota Mirai) the range quoted was still something around the 250-300 mile mark? Can't recall exactly I confess. So that's still less than half the range a modern, efficient diesel car will do between stops. Now you may say, how many people actually need that sort of range? Surely 300 miles is enough for all except the most extreme of road warriors, and even then, assuming there's a public refuelling infrastructure in place, it's hardly going to be an issue to have to fill up twice as often. Thing is, we already have BEVs capable of 250-300 miles on a single charge, so unless HFCs can be given a significantly better range than that, they aren't going to answer that question. As both battery and motor technology improves, we'll see greater efficiencies and higher charge densities which will push the BEV range still further. And already the best ones are equivalent to many a petrol engined car anyway, and no-one complains at that sort of range in one of those. So at what point do you stop worrying about how far your car will go? 400 miles? 500 miles? How far do you actually drive in a day anyway? Really? Regularly, that is, not exceptional one-offs like visiting Auntie Mabel in Inverness (from your home in Penzance). Still, all that aside, I think HFCs are an exciting alternative to what we currently have, and it's a shame that it seems to be taking so long to get viable commercial models to market. I wonder if we will start to see alternative hybrid cars come to market as the initial models, featuring both a fuel tank / cell AND a smaller battery, so that you can use either method to drive the motors? So a similar sort of principle to the current hybrids available now, but using two alternative energy sources rather than hydrocarbon-based fuel. That might possibly be a stopgap until the hydrogen fuelling network ramps up. I'm well aware of the various arguments about the "true" environmental credentials of BEVs and I don't want to get sidetracked into that argument at this point. Suffice to say that every single action we take as human beings, from breathing and cooking to mining lithium ore or casting aluminium (and not forgetting jetting off around the world on holiday or buying a new pair of speakers) has an environmental impact, so unless we are all going to crawl back into caves and live on berries we are unlikely to ever have a very clean conscience environmentally. We can, however, take steps to reduce the damage done and to minimise our impact on this beautiful world we share, and the new age of transport heralded by hydrogen will probably be a significant step in the right direction. Peace, out.
  14. Hi Barry John's (Lurch) bake-off is on the 17th Nov so you may not get too many takers for another one the day before! 30th Nov or 7th Dec are good though, I'd love to come along as I'm only in Southampton. Jules
  15. Thanks Bob! F206 is now moving from the pre-shortlist to the proper shortlist. The 208 is significantly outside my price range unfortunately, new at least. Plus it doesn't come in white, which I confess is a major consideration for the purposes of maintaining domestic harmony
