  1. Correct; old models. The 3 was the DEQX more than 10 years ago but has since been superseded by the 4 and the 5 and the "Pre" variants. The 3 had a max input of 96k so a sign of its time. There were purchased-separately-add-on digital-out board and 2 versions of a balanced-out analogue board for the HDP3. Plug-in daughter boards. I had a HDP3 and I'm pretty sure it had 2 families of filters (48 and 96) and (44 and 88). All input is resampled to, and processed at, 96 in today's models. The sweep tone, measurement and filter generation were all done in 96k (48k in really early models). The 44, 48 and 88 filters were then numbercrunched from the 96 version. But got me thinking ... Get a 96k filter and numbercrunch it to say 44 (as was done in the HDP3) Have a 44k input and numbercrunch it to 96 (as is done now) Same conceptual process but in inverse. Nothing to be gained, is there? Both a result of non-integer crunching. [Which is why I don't bother getting my MSB transport to integer-resample CDs (I play CDs exclusively) to 88 as the DEQX resamples to 96 anyway so it may as well do it from 44.]
  2. Not tempted by anything much at the moment. Content with what I have. My MO is to start again from scratch every decade or two. Yes my 'lifetime' was maybe a little flippant as everyone builds up from a lower base step by step to get somewhere where they are happy. But I think about taking big steps; gets a bit of hand-wringing and anxiety out of the way. Haha; and at my age my current amps may well be lifetimers .
  3. The amps that I ended up with were the only ones (that I tried) that did the job that I needed. The others sounded (mainly) strained and crystalline including some other well known and highly respected brands. Probably hard to pick between anything if all they are playing 300Hz at 60dBSPL, but push them a bit harder with music at preferred level into recalcitrant speakers and differences are there to hear. Horses for courses. In any case I would prefer to run something at a sweatless half rat power than something huffing and puffing to achieve the same result. I would be tempted to have the so-called arc welders in any system irrespective of speakers. Buy once; lifetime purchase; sure beats (and is cheaper in the long run than) regular to-ing and fro-ing with lesser amps.
  4. I reckon that they have missed the most important feature ie the triangular braced design that supports the height (mine are over 2m tall) by utilising a rod or two from the top back down to the feet behind. And I most definitely needed spikes to get through the carpet to the concrete beneath, otherwise they just floated on the carpet and moved with the slightest touch. With bracing and spikes they are absolutely rock solid and is probably the best thing that I have ever done. Image is just as solid and pinpoint as the speakers themselves. I tilt mine using a chunk of wood from the garage; no expense spared! Mine are tilted forward at the top because of the height. Looks a bit precarious! Not sure that tilting has made any difference, though. I can understand why a commercial operation doesn't do the triangular trick, 'cos they can't be sure where the existing screw holes are. With DIY one can make the bracing rods exact to the existing screws. A really ancient photo (I think that these may be my older MG3.6R) but you get the idea...
  5. It's the English language again. You can interpret it both ways. I reckon that they wanted to say that they are increasing (improving) the performance and are doing so by decreasing sound transmission. So increasing and decreasing sort of mean the same thing depending upon what is being increased and decreased. --------------------- On room acoustics ... One must be careful about what one wants to achieve in an audio room. There is a very marked difference between sound-proofing and good room acoustics. Sound proofing keeps the sound in by reflecting it back into the room, making it a lot more difficult to control, whereas some of the best sounding rooms deliberately let the sound escape to the external world never to return. Light flimsily constructed rooms are often the best acoustically. Concrete bunkers, which might be great for the neighbours, need not apply.
  6. Yep. Which is what I do. I rip with dbPoweramp (Windows version with reference add-on package containing the HDCD decoder) which will do the expand to a 24/44.1 file. The Mac has no HDCD decoder of any sort (that I know of).
  7. Maybe, probably not, can't tell. There are too many releases where the engineer didn't understand the engineer understood but did it incorrectly because of secrecy of instructions the engineer understood but decided to only partially implement the features the engineer didn't do anything at all except use Pacific Microsonics hardware Hydrogen Audio calls recent ones "zombies" since they are likely to be by people just using Pac. Micr. hardware without any attempt at using the HDCD features. ie. looks important on the packaging and will turn the blue light on but is really just a normal CD. Then there are those mastered using the hardware but since there is nothing turned on they do not advertise the fact. There are of course HDCDs that are done correctly, but not many. There almost certainly isn't a non-HDCD version to compare the HDCD version with, so I guess one will never know if a particular HDCD sounds better. No point in comparing a HDCD played as a normal CD to the same HDCD with expansion because the HDCD has been modified at the ADC stage and is by definition not normal (it has had the HDCD digital amplitude and compression filter(s) applied to it). The expanded ones (as played by a compatible player or by appropriate software) should have an increased dynamic range over what one may expect from the mythical standard CD of the same thing. like lots of other hi-rez things the end quality is likely to be a function of the person doing the mastering rather than the medium used.
  8. Yes, me, a long time ago. https://www.stereo.net.au/forums/topic/51488-hdcd-disks-revealed/ A promising technology that wasn't really done correctly by many of the people using it. The result at the time (with my HDCDs) was that many were just normal 16bit CDs that turned the blue light on.

    The Ashes

    Yes. Practice is one thing but having the technique to swing the ball and to do it with control is another. The English bowler James Anderson is a master of swing but can barely take a wicket in Australia. Interesting to see how Starc will go in this test.

    The Ashes

    There are 2 major manufacturers of international standard cricket balls. Dukes is an English brand and Kookaburra is an Australian brand. Their method of production is a bit different. Dukes have more prominent seams so will swing in the air and deviate off the pitch more than the Kookaburra. Dukes are used in test cricket in England. Australian batsmen tend to have more trouble with these balls since they are not used to the extra movement. Conversely English bowlers have trouble with the Kookaburra ball when they bowl in Australia because it doesn't move enough for them. White balls are made by Kookaburra. White leather gets dirty more quickly so they have extra coating to preserve them. It is said! that the white ball swings more than the red ball. The manufacturer says such is not the case. They say that both balls are made exactly the same way on the same production line. It must be an optical illusion or different atmospheric conditions that causes a difference if there is one, which they deny. It's the old opinion vs. fact argument. Power cords , anyone. As an adjective, "red ball" cricket is a term used to describe test and first class cricket and even Saturday afternoon at the park cricket. "White ball" cricket is the description of limited over cricket which is often played at night where the white ball is easier to see under lights. Because of the nature of the game and rule differences, there are different strategies, tactics and skills involved in playing limited over cricket - a bit crash and bash. Test cricket is much more nuanced and the game can swing back and forth over the longer playing time. Even long periods of apparent nothing can be quite absorbing.
  11. I have a suspicion that "digital out" PCM over SPDIF (Toslink or coax) from a DVD-A will be down-sampled to 48K maximum if the original is say 96K. It's part of the DVD-A and SACD licensing not to let hi-rez data escape into the uncontrolled world where it could be copied/pirated. If a transport is sending say 96K to any miscellaneous external DAC then the transport manufacturer is being particularly naughty. I reckon that an external DAC will be presented with 48K; ie roughly the same as a CD but most likely with a different mastering, which is most likely the advantage over CD. [Your BIL is right in that hi-rez can be transmitted via HDMI (or via proprietary connections) but there are rules about that too and the digital stream won't get to a miscellaneous external DAC. In any case will the 48K be any worse than the 96K? IMO its the mastering that matters most which you are getting whether it is 96K or 96K down-sampled to 48K.]
  12. Item: A box of 78rpm records from the 30s?, 40s?, 50s? Location: Newcastle/Hunter Valley Price: Free Item Condition: Various, of course. Probably what you might expect from 70+ year old records. Reason for selling: Give away to interested local collector. Payment Method: Pickup Only Extra Info: Records from my parents and probably their parents deceased estate discovered when clearing out the house. Packed away in the box in 1971 judging from the newspaper wrapping. It appears as though each record has been wrapped individually. There is a wine box full, so I guess about 100 or so. I unpacked the first 10 to give an idea. Seems to be popular music of the time.

  13. My "deluxe" CD is awful too. So is "Lungs" Deluxe CD. Avoid. In fact all of Florence appears to be heavily compressed. http://dr.loudness-war.info/album/list/album?artist=florence+%2B+the+machine
  14. I have them too. They are Vicoustic DC2 They come in a 6-pack and are about RRP $700 They are white grey or black. They seem to be denser than normal polystyrene. [Tobes types faster than me.]
