  1. confirm this or not - the JB980 - you cant change the bit lenght 16 or 24 bit? any one getting a sony deck these days should also get a spare load belt from ebay as after all these years the tiny rubber belt that ejects the md is likely to be on its last legs?
  2. here is an interesting podcast on louspeakers and rooms that may interest some here. "Paul Hales, founder of Pro Audio Technology, talks about room correction—or as he prefers to call it, room compensation. Topics include some of his fundamental principles of room EQ, sound directivity from various objects such as violins and speakers, how microphones do not capture sound in the same way that human ears do, how sound interacts with small to medium-sized rooms, target response curves (including the X-curve), how conforming to the X-curve causes the sound to be louder and more harsh than it should be, his suggested modification to the X-curve, answers to chat-room questions, and more." interesting podcast - Pauls Hales take is that we live and move in rooms where we hear live music and sounds so rooms are not a hindrance to hifi ( get the earphones out? no ) but part of the experience as they would be in a live concert. He cites the example of how terrible a violin can sound close to without the support of the room where it is being played.
  3. added both parts in pdf format
  4. here are the parts part 1 Hi-Fi World 95 June 2016 Minidisc nostalgia.pdf part 2 ( updated ) Hi-Fi World 96 July 2016 Minidisc nostalgia.pdf
  5. rather interesting look back at our much loved system from HiFi World from 2016 "Today, Minidisc can still hold its own. I’m impressed at how much of a digital CD transfer’s space, rhythm and detail emerges intact - despite ATRAC’s data reduction ratio of 5:1 (or higher!). Even symphonic and chamber works fare better than one would expect, the depth and soundstaging of a good recording being largely retained. The caveat is that a decent external converter is used for playback; enormous strides in DAC technology have taken place over the past fifteen years or so. " The conclusion he comes to is that pump the data out thru a modern DAC and the system is still good see later post for pdf files
  6. well one question since Atrac is a discarding codec rather than an zip/unzip one are the resultant files actually decoded on playback unless they are encrypted?
  7. I dont know why you are taking issue with what I say as I am not saying any of the above which u are taking out of context and misreading
  8. yes was talking about normal Atrac - I know there are other more modern systems that remove redundant data that can easily be replaced on listening - similar ideas no doubt to how hard discs can be compressed. the op seemed puzzled at why atrac dont need uncompressing and presumably "superior" to eg Flac
  9. the compression only applies to reducing the size of the resulting file, where datas is THROWN AWAY - its not a zip/unzip idea. Atrac codecs used various psycho-acoustic facts like if 2 sounds are of the same frequency with one quieter than the other , you wont hear the quiet one so can be discarded without impairing the sound you hear- maybe a Martian could hear the difference but Humans cant
  10. another one at a low price in whats looks like to be good condition on UK Ebay - also this one
  11. a new low start price MZ-B10 on UK ebay worth keeping an eye on over xmas ( when people are away ? )
  12. if you can find any......
  13. it aint as simple as you think to replace the belt. is very easy to damage the mechanism. some one here already has...... there is a thread here on it if you search
  14. The sony MZ-B10 doesnt have tone controls unlike other of their models but does have 2 sound settings that emphasise voice - I think they added this to make the little speakers they have include half useable - and it works quite well even for simple vocal music ( it aint hifi more like a tranny ) - the speakers is the reason I like the portable as some times cant be bothered to get out the headphones.- that and the battery life ( the 2 panasonic AA i am using must have run atleast 10 hrs now and still the battery level says full )
  15. no never seen one of those - but seems to be an earlier version ( 2001 ) of the B10 ( 2003 ) - same sort of thing "business recorder" from the page seems to have stereo mic than the mono of the B10. also only uses 1 AA battery so wont last as long. No indication of the atrac type so presumably not R/S as the B10 has. UK Ebay has in the last few months had quite a few of the B10 at good prices - one a few days ago went for I think £51 - mine were no more than £60 each. so they can be got at a sensible price. matter of waiting and telling ebay to email when a new offer comes up
