Uneven speaker cable lengths? This will influence the damping factor of your amplifier, which will, again in theory influence the ability of your amplifier to have control over your loudspeakers, wihich would be a little diffirent for both loudspeakers.Difference of 1m both wa... | |
Uneven speaker cable lengths? Many people will tell you that it won't make any difference. On the other hand if you believe that cables affect sound then most likely this effect will be proportional to the length of the cable. I might not be able to hear the difference but I w... | |

Gainclone LM1875 class D chip amps LM1875 is 20W class AB amplifier. | |
RCA or Optical? Optical does not pick electrical noise or create one (no transmission line effects) but transitions are slow making it more susceptible to system noise, affecting threshold point and creating jitter.Coax has faster transitions making it more immun... | |
Asynchronous vs Synchronous In synchronous USB D/A converter clock comes from the computer. Usually D/A converter runs from internal clock that is synchronized with incoming USB clock by PLL (Phase Lock Loop) but it is less than perfect. This scheme is used in pretty much ev... | |
Directional speaker cables - switching direction Many believe that direction should not matter since we're dealing with AC current (charge flows in both directions). It might be a little bit more complicated than that, since energy is delivered only in one direction by the electromagnetic field ... | |
Bi-Wire Tuning Jeff, Belden 5000UP is a stranded bare copper cable - the worse to use in my opinion. According to Audioquest thick cables produce skin effect that changes impedance of the cable with frequency. Skin effect starts at gauge 18 (@20kHz). In stranded... | |
minimizing glare on TV screen Mark, I have 55" Samsung LED with very shinny screen. I don't see a lot of reflections during day because it is facing wall without window while brightness automatically adjusts itself to much higher levels during day (Samsung calls this "ECO"). A... | |
Does the Transport make a significant difference It can make it better because of better mechanical design. quieter power supply and better output stage, but it can make it worse if output slew rate is high (short transitions) and your coax or DAC is not perfectly matched. It is a system thing. | |
The first watts After transition from class A (both transistors conducting) to class B (only one transistor conducting at given moment) it is already linear and class name doesn't make any difference. Actually, increasing bias point to keep it longer in class A w... | |
Do I really need a preamp? "It depends" is the best answer because it involves a lot of factors including personal preference. Mentioned class D amps are in big part based on modules that have low input impedance (for many Icepower modules it is 10k). My class D power amp h... | |
Frequency range s of digital noise s Any cable can pick-up electrical noise including speaker cable. Shielding is based on skin effect and does not work for lower frequencies. The key is to keep cables as short as possible, since they become effective receiving antenna at about 1/10 ... | |
Frequency range s of digital noise s Pss, personal computer clocks might be in gigahertz range but computers also contain switching power supplies that operate in hundreds of kilohertz range and buses operating in hundreds of megahertz. In addition when signal is not continuous, but ... | |
Frequency range s of digital noise s Pretty much whole spectrum. Very high frequency can get in and produce audible frequencies by mixing on any non-linear element or by "rectification" in components, such like op-amps, that have different slew rate for positive and negative transiti... |
