An interesting experience with power cable.


I’ve read a lot about power cables throughout the years and finally took a leap of faith and bought 1 silver-plated power cable. Of course I immediately plugged it in my amp and turn on everything for a listen. I could hear a tiny improvement but honestly was underwhelmed. I plugged the basic cable back into the amp. I plug the upgraded cable into my DAC for fun.

 

WOW, immediate and significant improvements. I gained a substantial amount of smoothness and sweetness and perceived clarity was also improved. I have alternate the upgraded power cable into the amp a few times, each time I get the same results, underwhelming, not as dramatic as if the cable went into the DAC.

 

So that was unexpected, I’m not saying power cable for amps are not significant. What I’m saying is, if you have only 1 upgraded power cable, the rest being stock basic, then plug it in your DAC, you might be surprised as well. Thanks for reading fellas.

 

Very curious to get a 2nd cable for the amp now.

@carlsbad That is possible. I do have a monster of an amp in terms of size. 90 lbs and it has a 2,000 watts toroidal transformer in the supply or something like that. I suppose that’s a lot. One thing I have to note is with the new cable into the amp, it doesn’t sound like it’s lacking in power, it seems to my ears that the amps are more hyper-focused and felt like I’m hearing the shortcomings of my upstream, in this case the dac. The thing is I can't imagine the basic stock cable can be less "undersize" than the new one I bought. 

 

@gammamike Yea $500 is too expensive for me right now. I have to remember what you say in the back of my head. I’m currently looking into acquiring the dac that is supposed to pair with my amp, some sort of current injection technology. Thanks.

@williewonka  Thanks for the plate of knowledge and the effort you gave. I've saved Audio Envy into my audio log book. 

@carlsbad  Those tube amps can draw a lot of power don't they. 

I believe mine is 8 gauge, not sure. it says "8AG" idk what that is.

 

@audphile1 I've never heard the difference with cable break-in but I don't refute the idea. Mine is probably at 70 hrs. 

@boomerbillone Thank you. I'm gonna say something related. I have known the BMC audio brand for less than a month and I have massive respect for the brands and the products they make. I own their amp. Their USB1 (active) cable is also highly praised by a reviewer (John Grandberg) I highly respect. Bmc also makes a nice power cable for their amp that is a bit pricey at 600 euro. Something I would buy in the future. 

 

I think you should take a look at the USB1 cable at 300 euro. 

@ghdprentice Hi GHD, please read the above post as it has some information you're asking about. 

I have the BMC S1 amp that I absolutely adore, gorgeous to look at and still seem to have more to offer with its designated DAC. BMC also sells a power cord for 600 euro. 600 euro I can muster, 2k for the Hurricane, that'd take me years. And definitely with a lengthy trial. 

 

Right now when it comes to cable, the action USB has my biggest interest. 

It has recently come to my attention that my amp has something that might've affected my experience with power cables. But first I want to confirm that my experience with power cords have been very positive. All stock cables the sound is meh. Worse than meh. Pc into the amp the sound is better but still a bit rough and edgy. I've left the cord in the amp for a few days to listen to music and banish the thoughts of cables but always reminded the sound is meh and I'd go out of my way to put the power cord back into the dac instead. Beautiful sound.

Ok so I found out my amp came with the synergistic research blue quantum fuse pre-installed. That might have affected my experience in some way. Reading up on the fuse was interesting and it's nice to be told that X component will dramatically improve your sound.

But every time SR releases a new fuse they say this fuse is the biggest jump in performance they've ever had. Going to purple = biggest performance jump ever. To blue to orange = biggest performance jump in the history of the company. Reading about it got old real quick and made me a bit skeptical 🤣
