  1. Some say that they can detect a difference between real-time playing of FLAC versus WAV. If so, it is likely that the difference is minuscule and probably due to computer hardware/software problems rather than the storage type itself. I haven't experienced a difference myself, but my player software reconstitutes the FLAC file to PCM and then loads the PCM into a very large RAM buffer and is played from there. So, no chance of any interaction with the un-FLAC-ing process. In any case the computer power needed to un-FLAC a file is trivial. So, I would say "no advantag
  2. FLAC is a compression algorithm (analogous to, say, Zip, or ...) (plus a few other capabilities like storing meta-data, cover art etc.), for taking a music file (the raw material is PCM encoded digital data) and making it smaller, yet still retaining the original content. Nothing is lost, nothing is discarded ie. it is lossless. It is the whole point of FLAC that it makes the file size smaller by being cunning about the storage process. Of course you need an application to understand what FLAC has done so it can restore the file to its original bit perfect state before or during
  3. Further reading for dipole owners http://rtaylor.sites.tru.ca/2013/07/17/optimal-toe-in-angle-for-a-dipole-loudspeaker/ [Look who made a comment.]
  4. ???? All of my CD players over the years have been said to output 2v or thereabouts single-ended. With no amount of mathematics can I turn 310mv into 2v. Isn't the relationship between peak v and RMS v about 0.7 (or 1/0.7 = 1.4)? What am I missing? [~300mv was the number used for tape-in, tape-out, tuner and aux amp inputs on amps in the olden days] [Sorry, a bit OT but has been raised already]
  5. We have a 1920something pianola and a cupboard full of piano rolls. I'm just waiting for the day ...
  6. I have 3 copies of my ripped CDs, DVD-As and downloads on removeable USB hard drives. 1 in the "music" room - can play from this but never do. 1 in another room 1 in another house in another suburb in mum's sock drawer. Hard discs are all different ages so they don't all die at once. Rotate through them to keep them at least a bit used.
  7. Indeed. It is well-known that mastering non-classical CDs with excessive dynamic compression is not only destructive of an otherwise good recording but is also so common that it infects almost all CDs from about the mid 90s onwards. There are enough good'uns around though and some artists seem to have a well done catalogue. Be wary of "remasters" - normally only useful for playing in the car. One needs to be careful selecting which mastering one buys if there is a choice. As far as good cheap buys at the local op shop is concerned - if you live in the country then forget it. Y
  8. I had Acoustat III ' s (full range electrostatics) for 25 years then switched to big Maggies. Looking for a change at the time - in fact, I changed everything. After 10 years I am happy with the M's and if I were to change I would only go further up the M chain to the big daddy. In one word, the electrostatics are "fizzy" in comparison, the big Maggies are "smoother". Can't comment on the smaller M's though. I think that the M's get "richer" the bigger they get. Due to better foundational bass - maybe. In both cases they need good amplification; and as y
  9. Welcome David. Plenty of chatter here to keep you occupied. Some of us even have Maggies too - haha.
  10. Hi Leon, IMO room reflections are the NO 1 problem in every system and treatment is the best bang for buck. My experience (which may or may not be useful for you) is ... Important to get speaker placement right first. I measure to see where gross problems are. It's cheap to measure and then you can put effort into wherever 1t is required. Or you can do it as an adventure and just go for it. You can always toss it out if it hasn't worked to your satisfaction. I bought twice as much as I thought I would need - have used all of it. I
  11. Never made much sense to me either. Maybe ... just maybe ... it is to do with the membranes being stretched so tight that they simply don't move air and require you to put the boot in to sound good. Mine have 2 layers of magnets in a push-pull arrangement, maybe to drive the big membranes with greater excursion. Don't know though. [Sorry Ratbob, I didn't want to turn this into a Maggie thread.]
  12. They can't. I think that they refused to offer sets for review if the reviewer didn't promise. I suppose if one wanted to do a comprehensive review with numbers I think that you would have had to buy your own. Can't find my references now - probably somewhere on Planar Asylum. I think that it was Stereophile's review of the 3.6R ? that started the war. I think that Seigfried Linkwitz was also involved?? Below is a quote from Stereophile chatter, but there was more at the time. Not really stuff that either side would air widely. Maybe things have changed in the last 10 yea
  13. Indeed Magnepan are being a bit sneaky, Magnepan claim 86dB at 1m for 2.8v. But 2.8v into 4 ohms is actually 2w. So a more reasonable number would be 83dB/w/m. But this doesn't make much sense either when considering that a German magazine measured my model at 77dB/w/m. Could this be why Maggies seem to go better with arc-welder amps. They may well be largely 4ohm resistive but on the other hand are grossly insensitive. What is reality? I also understand that Magnepan won't allow measurements be published by the media, saying something along the lines t
  14. Maybe. Not sure, but... I think that one would need some attenuator thingo to get the amplitudes out of the bass amp and midrange amp the same. They would have different gain/volume otherwise. Not many power amps have volume knobs. The midrange amp would still be amplifying all of the input frequencies ie bass as well, so it would not have been spared some of its effort. The bass would be truncated at the speaker not before. The passive XO components in the speaker will still be doing exactly what they were doing before. One part attenuating bass the ot
