  1. 1. Good locks on all doors and windows so they have to break something to get both in and out. Stereos are hard to fit through a broken window. If they are pros then they'll just smash the door. 2. Good insurance. 3. A security system that notifies you and sets off an alarm—and neighbours who are friendly and aware of noises, or you can spend a lot of money on a monitoring system that notifies the police. Be aware that false positives can be expensive. 4. Weapons as a last resort to protect life. (We have a "home is a castle" doctrine here—South Australia—but guns are very rare
  2. SGR Audio (Australia) has been using all analog (including in the user-adjustable signal processing) since they started making speakers and amps about 20 years ago.
  3. OK, thanks. I'll get right on it. It should help with global warming too, eh?
  4. I've decided that it's about time I started counting down the circuits rather than up—to give me more time to listen. Do you know if I have to reverse the direction of the planet's circuit around the star to get the whole effect?
  5. What I find interesting is that most 'just listening' reviews prefer the 'NOS' or 'slow filter' settings despite their oddities.
  6. Most analog pots do have some difficulty at very low volume levels, and this is more noticeable in headphone/IEM use. You could try a DAC or preamp with a ladder resistor volume control or possibly a volume reducer somewhere in the audio signal line.
  7. Depending on how much the two channels in the stereo amp have in common (power supply etc.) there may be a lot of benefit or almost none at all. Assuming a dual-mono internal circuitry for the stereo amp the only advantage I can see for mono block amps is shorter speaker cables as the amps can be placed right next to the speakers. The disadvantage is that cases, some connectors, and switch gear would need to be duplicated. As usual, it's mostly in the implementation.
  8. That would imply that headphones couldn't produce bass at all, considering that the room is only a couple of inches in all dimensions. Get a new acoustician.
  9. Pre-amp is always on even when "off". The designer says that it takes hours for the temperature to stabilise and give the best sound so "off" just disconnects the outputs. Previous amp (same manufacturer as above) turned off completely and was said to regain its best sound after an hour +- when the output transistors reached 60°C. It was temperature controlled to keep them at that temperature. New active speakers have a very low power automatic stand-by mode. I'll have to ask the designer/manufacturer what's that all about. I know the sophisticated computer control is a
  10. I've got a nice Finnish-->english translator that would work if there was a text version of that.
  11. I'm not sure how newsworthy this sort of stuff is—but it garners clicks, so... With every new chip, every new operating system, there's always something that the old versions won't do. I started programming on IBM System 360 machines and nowadays they are only in museums.
  12. Offer to buy a small TV to save space. (or a smaller lounge) Very few people can hear absolute phase. Try it both ways and see if you prefer one or the other.
  13. If I had a piece of software that would compress hi-res music files and make them sound better than hi-res when played (REALLY) then I'm sure I could make money just selling it. Wouldn't you buy it? Why would I need to foist it on everyone with no choice allowed?
  14. IMO just play what you like. The guy who designs and manufactures my new speakers has doubts about "mechanical" break-in taking very long at all. Woofers cycle at (say) 50 times a second and tweeters at (say) 10,000 times a second. They should wear in fairly quickly at that rate.
