Power CABLES Suppose the power of an amp is 40W The current through the power cable is 40w/240v =166mA Most power cables are 10A current handling .166/10 x 100% = 1.6% is the amp current out of 10A cable too much cable capacity is been wasted now, a better cable will make much of a difference?

Interconnect cable shield is very important, many on audio forums think it's not required, some say without it they get better sound ,others say moving from analog line of ~600mv to digital line ~2v input signal it is not required,it's unreal, they don't understand why the shield is there?, they don't understand emi/rfi?.An unshield interconnect invites interference to interconnected equipment.Unreal!!... please comment...

unity gain makes a difference?, cable L and C make a difference?, cable R makes a difference? 1- unity gain, no way it makes a difference,all the gain is done by the amp. 2- cable L and C, I have tested many cheap and expensive cables and there has been no phase shift or frequency response issues,so no they don't make a difference,could be, there would be very cheap cables(rubbish) that would make my conclusion invalid but hey they exist because they are dead cheap. 3- cable R, no , because if there is a drop in signal , the amp has all the power to put it back up conclusion, a good cable is about quality and reliability.

Amplifier Class-B vs Class-AB I've been to audio forums and most people don't know the distinction between the classes and what are the benefits of each, Class-B could also be referred as Class-AB, but this is misconception, Class-B operates in Class-A for a few milliwatts, while Class-AB does in several watts,suffice to say Class-B aims at less class-a, while Class-AB at more class-a, what is the benefit of class-b, well it comes down to distortion, complimentary transistors in both classes switch at different levels,class-ab switching has more distortion because they're heavy biased in class-a and this causes distortion from class-a to class-b , the other thing of class-ab is less dynamics and punch when in class-a,although in class-a there is less distortion this is arguable in push pull class-a. Now let me mention the benefits of class-b, 1) few milliwatts in class-a this means more efficiency than class-ab, 2) faster switching because of less bias and this means less

MP3 Mp3 has the same frequency range and dynamic range as CD-audio, however what dumps is audio data (sample data) that make the least difference to the listener compared to CD-audio,thus mp3's sound quality is down to sample data which is debatable whether they effect audio too much again compared to CD-audio,anyway frequency range and dynamic range is the important factors not sample data because frequency range and dynamic range indicate quality and sufficient sample data.
