Are integrated amps technically better than separates?
It’s so interesting that folks think they need a high quality power chord and expensive interconnects. Never mind that just inside the wall is the cheapest copper lines the contractor could buy. It’s laughable. Just inside your loudspeaker is usually a thin generic cable connection between the crossover and drivers. You need expensive cables because it makes you feel better. |

Ohm's Law isn't like a speed limit; it can't be broken. By comparison, the solid core wiring in the wall is fairly high performance in terms of voltage drops along its length compared to a power cord, but it is illegal to use Romex or the like for power cords. The effect of the power cord is measurable and with relatively unsophisticated instruments. So the onus is on you to explain why they can't have an effect. I've seen power cords rob a 140 watt amp of 40 watts of its output power. If you are suggesting that is not audible as well... sheesh! Its pretty laughable. |
@erniesch, finally someone with a bit of sense. Thank you.... AT MOST, a 12 to 13 gauge wire is enough for 99% of almost all home amplifiers/subwoofers etc, up to approx 200Watts RMS/channel. Its ohmic resistance will be no more than 0.02 ohms for a 10 ft cable and will allow EASILY up to 7 amps (and that is very conservative, max is 30) giving approximately 850 watts. And the skin effect will be negligible until about 5300Hz. Since mains is at 60 Hz, there is essentially no skin effect. Here is the chart: https://www.powerstream.com/Wire_Size.htm And for monster amplifiers like 1000 watts/channel, you can always have a dedicated 50 amp cooker/range cable installed but think... how many times in your life do you crank up that volume to that level for long periods of listening ? |

Feel better, never.. PC and interconnects can cost a few bucks and a little time too. It can almost make up for some of the inadequacies, you pointed out.. Glad you noticed why every little bit helps....Your learning.. Took a while for me too... Regards |
