nbaptista Posted July 31, 2014 Share Posted July 31, 2014 (edited) I´ve bought a second hand a Kemp Lo Power for my amp, a Densen B 110. But searching the Web, I found most on line shops advice the Lo Power for sources and pre´s and the Hi Power for power amplifiers that need more electric current. Both cables share the same geometry, the only diferences are the diameter. Lo Power (5 conductors *0,75 mm2) Hi Power ( 5 conductors *1,5 mm2) According to this, do I need the Hi Power or the Lo Power is enough?This Lo power is definetely an upgrade to the standard cable.The Densen is a 60 watts amplifier Edited July 31, 2014 by nbaptista Link to comment Share on other sites More sharing options...

The issue, to my way of thinking, is that ... do the "Hi Power" cables have enough mm2 for ideal delivery to a power amp? For instance, what does "5 conductors of 1.5mm^2 each" mean? I suggest it means: 2x1.5 wires for 'active' (ie. 3mm^2) 2x 1.5 wires for 'neutral' (ie. 3mm^2), and 1x1.5 wire for earth. This is "under-powered", by my standards (for a power amp). I would say (for the ideal): the earth wire should not have less cross-sectional area than the other wires. the active and neutral (and therefore the earth) wires should be minimum 4mm^2 - and preferably 6mm^2 in cross-sectional area.

nbaptista Posted August 8, 2014 Author Share Posted August 8, 2014 (edited) The Kemp power cord is OK but is a bit laid back compared to the standard!Weird, no? Edited August 8, 2014 by nbaptista Link to comment Share on other sites More sharing options...
