| Digital crossovers? The DEQX gives you what I call "lowest common denominator" sound. I was able to borrow a friend's DEQX and try it in my system since people think it is the audio equipment of The Second Coming. Even on straight through settings (no correction appl... | |
| Accuphase CDP Owners - Straight to Power Amp?? What type of volume control is built into the Accuphase DP500? An analog volume control (i.e. potentiometer after the DAC), or digital volume control (i.e volume is changed digitally before the DAC)? | |
| Digital crossovers? These are good up to a certain level. Once you get beyond a certain price point the built-in DAC's in these units are not as good as aftermarket DAC's. The other disadvantage is that these are PCM only, so no DVD-A or SACD. Also, if you want to us... | |
| Quad ESL 2805 or Avantgarde uno Horn? So far nobody has mentioned this - but you need to consider your listening room. Both speakers are very sensitive to listening rooms but for different reasons. You need to sit ideally 3m (9ft) away from the Avantgardes. You can get away with 2m (6... | |
| 6X9 Car Speakers Rear speakers in a car are the same as rear speakers at home. They should only be used to fill in the sound, and NOT to be used as your main source of sound. I would not bother spending money on the rear speakers. In fact, in my car, I disconnecte... | |
| Customizing sound through digital interconnect Dazzdax, you and I and everybody else knows that cable, no matter what type of cable, can not improve the sound - it can only degrade it. As to how you judge a good cable ... well you listen :) I don't go by oscilloscopes either, I go by what I li... | |
| Wadia CD players direct to power amps opinions I don't know how the Wadia pre works, but there are only two ways which it can work: - as a digital pre. This is definitely inferior to an analog pre, because it throws bits away, compresses dynamic range, and brings the signal closer to the noise... | |
| Customizing sound through digital interconnect Dazzdax, think of digital bits as square waves rising off the noise floor. The noise floor can be raised by reflections and other random noise in the interconnect. The tops of the square waves can be smeared by skin effect. The noise is random, an... | |
| Customizing sound through digital interconnect Dazzdax, DA conversion is not digital, it is analog. This is not the same as computers, which is not time critical, and if the data is corrupt the CPU can simply request the data again. In a DAC, if the datastream is jittered, it will affect the c... | |
| Customizing sound through digital interconnect Dazzdax, digital cable is even more sensitive to imperfections than analogue cable. For one, the 1's and 0's are square waves, and square waves consist of the fundamental + an infinite number of harmonics (as per Fourier). So the frequencies trans... | |
| Why do amps sound different? Another interesting thread with great contributions by everyone. Is someone able to explain the difference between "current paradigm" and "voltage paradigm" amplifiers? | |
| Help with math and science of tri-wiring? Yes Cford, but on some speakers the impedance variation between the mid/tweeter and the woofer is quite different. The "nominal impedance" is an average of the impedance curve. My speakers can be tri-wired. Admittedly mine are a special case - twe... | |
| Thoughts on adding a Super tweeter . Depends on the horn speaker! Horns are designed to work over a fairly narrow frequency band. If the wavelength is too long to fit the horn, the horn won't effectively couple the motion of the cone to air. End result is - sound is attenuated at tha... | |
| Help with math and science of tri-wiring? Jsterrit, perhaps Jon Risch's website can help you? See here: http://www.geocities.com/jonrisch/biwiring.htmHere is another good article on the subject. I don't necessarily agree with everything he says, but he's right on at least two counts - cab... | |
| Help with math and science of tri-wiring? Actually, this is a very interesting question! I have never thought of doing that. KR4, is there a reason why all the wires should be connected to the same tap? I mean, on my amp ... the 4, 8, and 16 Ohm taps are just slightly fewer coils on the o... |
