Power Cables on Subwoofers do Matter

I read an opinion somewhere on this site that swapping the power cable on a subwoofer has a minimal effect and may not be worth it. I have a very different opinion. Power cables can completely transform a subwoofer’s performance.

I have an SVS SB-2000 powered sub and my preferred power cable, a Zavfino Fina, has made it sound like a different animal altogether. It has much more punch, freq response linearity, and liveliness. The manufacturer included power cable makes it sound slow, bloated, and almost out of tune just because it’s sloppy, in comparison. The only drawback to the Fina is that slam below 30-40 hz is a little recessed but it’s not major and is still clearly my choice. I also compared five other aftermarket power cables from other components in my system and they ALL had a different effect on the sub. For testing, I used various crossover points and most of the testing was with the loudspeakers off in order to isolate the sub for critical listening.

Cheers!

The current is sourced from a transformer placed somewhere far away outside the building. Then it passes several long cables to the building main panel where is distributed through other cables to each apartment or whatever place. Then it goes in the home distribution panel and then to each plug

Shhh....don't be tossing reality around like that.

Too bad Zavfino doesn't offer a 90 degree IEC. Thats the only way it's going to work on my REL. With the REL in the corner behind the left speaker there is absolutely no room for a straight IEC back there. The cheap freebie just squeezes in there. 

Same with the aftermarket Signal Cable REL Speakon link. I ordered a right angle Speakon to put on it so it can fit.

Voodoo makes high quality right angle adaptors that you can use.

@gladmo, the svs sub does not use the standard connector on their plate amp. I have the smaller SB 1000 Pro which uses a C7 I think it's called. Does Zavfino give you the choice of connector.

Also the Fina you mention is 14AWG which is considered a bit lightweight  for power amps. Why did you choose this instead of their 12AWG version? I realise of course that the heavier cable will cost more.
