What drives me crazy is people who seem completey unaware that the aspect ratio is set all wrong on their TV and they just sit there watching stretched or squashed people on the screen :mad: :mad:

(working in TV production) I am often surprised by the amount of (professional) people miss this / get this wrong before transmission.

Well, yeah. This doesn't mean anything though. If you're still only using the speakers internal crossover adding more amps makes fuck all difference. The whole point is that by putting a crossover before the power amp stage for a driver, rather than after it, you can have an amp running at the optimum range for the specific driver it's feeding, rather than having to amplify a full range signal that then get's filtered down by the speakers crossover.

these preamps have crossovers built into them: http://www.jahtubbys.co.uk/equipment
I'd like to have a play with one. it's not "high fi" of course tho, it is just for LOUD.
 
Some terms to try and help explain it:

Preamp - takes the various line level signals you have and sorts them out for you. In a big PA system this is the mixing desk, in your home hifi it's the bit that lets you select "CD", "Phono" etc

Crossover - Takes the full range signal and splits it into a different number of frequency bands. Sub may be everything below 100Hz, mid 100Hz to around 2K, Hi everything above that etc

Power amp - boots the low level signal from the preamp or mixer into something that can drive a speaker
 
then you want the bass signal to go through say a 30000watt amp power amp and 18 inch speakers because bass if more important, and send the middle through a 1000 wat amplifier and whatever other medium size speakers you have lying around, then all the treble through some car stereo amps linked to phone speakers so that it doesn't matter when they blow.
 
Exactly. Bass needs a lot more power than a horn, so by splitting the signal before the power stage you can optimise each amp for the load it will be feeding.

Think of it this way - if you have an amp that is amplifying a full range signal that is then reduced down by a crossover in a speaker you are wasting a lot of energy because most of what it's doing will be ignored. By only having an amp work on the frequencies actually needed you increase the power available to that driver and thus get more volume/headroom/quality etc

What in hooting heck is professional TV calibration?

Someone charging hundreds of pounds to come to your house with a spectrometer and calibrate the TV so it matches THX standard (which I know fuck all about, except that it's some kind of cinema standard).
 
Cardas patented, "Constant-Q" construction places the smallest of the Golden Ratio strands at the center of the conductor to reduce stored energy and conductor resonance. Cable resonance is further reduced with controlled propagation, Crossfield construction, matching conductor and cable loop characteristics with carefully computed strand layering

Bi-wired? Pah. TRI wired is where it's at.

That whole website is a treasure trove of bullshit :D

The metallurgical advancements and metal testing techniques that have evolved from this project are finding applications far beyond anything ever imagined. Insights into the basic conductor dielectric relationship have lead to a new frontier of understanding and an associated patent, but it is the dramatic silencing of the cables themselves and the completely unimaginable improvement in depth and clarity of sound that was the real reward.

Without it the 1s aren't straight, sometimes they come out like a j or even worse an s. Meanwhile the 0s are squashed and no longer maintain that oval shape so your stereo can't tell if they are 0s or Os. Disaster!

I just think of all those poor people using cheap USB cables to connect their printers and having to go through their print-outs and correct all that by hand :(
 
I've just realised I've been using the wrong kind of fuse. I need cryogenically treated ones.

Enter the HiFi-Tuning range of fuses, these replacement super premium fuses are hand-made and tested in Germany. The Supreme ranges of fuses are tip-to-tip of 99% silver combined with 1% 24 karat gold. This is similar to the material used in the highly desired Mundorf Supreme silver/gold capacitors. Mundorf developed for HiFi-Tuning a special silver/gold solder for use in the Supreme fuses.

The fuses have also been resonance-optimized to control vibration. According to HiFi-Tuning, "The drawing process for silver (or copper) wire causes micro cracks in the surface of the wire. The cooling process also results in imperfect crystal grid structures. Both of these 'deformities', relative to the ideal of a perfect conductor, result in surface distortion when current flows through the wire.

The addition of 24 karat gold fills the micro cracks and the empty spaces between the crystal boundaries to improve transmission properties, while also inhibiting the surface oxidation and tarnishing that will occur over time otherwise." These custom, precious metal fuses are also cryogenically treated. Finally, the Supreme fuses are treated with a proprietary quantum level process.
