I've read some things discussing speaker wiring such as speaker reviews and their is always something like "the included cables are ok but you'll probably want to go and get something thicker." My question is why do I want some huge python of a cable? And what principles are used to decide what size is big enough?

ABX result of 2xCAT5 cables per polarity (4x8 wires/speaker) versus thicker 'lamp' cord (sorry didn't measure any gauge/diameter) (both 3m long)
playback: 'inherited' MPC (Dire Straits - My Parties) -> FB2k (24bit/dither/ASIO) @-12dB/replaygained -> M-Audio Delta 410 directly to poweramp (193W sinus power in 4Ohm)-> cables in question-> Infinity Reference standard II speakers (don't have impedance curve but I guess it varies from a near-short to 8-9Ohms). Recorded at one speaker binding posts using 20Kohm & 1Kohm resistors to adapt the signal to line-in levels for Delta 410 (http://www.hut.fi/Misc/Electronics/circuit...er_to_line.html). Needed to make sure that the speakers are sucking the amp dry *- attenuation was a bit too much for the line in (the sound is a bit grainy) - noise level was around ~60-70dB in Sound Forge 6, signal levels around -20dB, 24bit 88khZ. Removed DC offset, normalized to ~93%, resampled to 44.1 using Anti-Alias filter/4, noise shaped & dithered down to 16bit. * that's at normal-to-medium loud listening levels ------------------------------------- WinABX v0.4 test report 10/31/2003 14:49:30 A file: E:\30sec_2x2_cat5.wav B file: E:\30sec_big_cable.wav 14:49:48 1/1 p=50.0% 14:49:57 2/2 p=25.0% 14:50:03 3/3 p=12.5% 14:50:16 4/4 p=6.2% 14:50:56 5/5 p=3.1% 14:51:03 6/6 p=1.6% 14:51:16 7/7 p=0.8% 14:51:26 8/8 p=0.4% 14:51:46 test finished Should I upload the files in case someone is interested? The difference is more than OBVIOUS! edit: files uploaded http://www.hydrogenaudio.org/forums/index....showtopic=14732 edit2: corrected resistor values; added link to speaker to line-level adaptor This post has been edited by lucpes: Oct 31 2003, 22:49 |
