Bel canto monoblocks and power cables

I have ref1000m amps. These draw a lot of current when powered up not so much after. I use basic cords on those. Higher grade shielded cords on source gear. The amps power supply seems designed well to have power in reserve when needed. So I have not felt a need for beefier power cords. The amps are very efficient sound great and never break a sweat. Beefier cords not needed as much in some cases compared to others. Devil is always in the details.

i have 3 ref 1000m amps across my front in a HT configuration. I have used Crystal Cable, Siltech and now Purist Audio Designs (Neptune). I can def attest to a change in the tonality as i moved across the power cords.

it may be that the power cords you have chosen actually sound similar and therefore you didnt hear much difference. 

@thomaswv - Like you, I found good PC’s on my NAIM amp did not make an immediate noticeable difference - I had to find the right track that made the improvements more noticeable.

Those improvements are the micro details of the venue acoustics - now I know what improvement power cables make it is easy to hear and noticeable when you change back to a cable of a lessor ability.

I use the following DIY cables that I have compared to a few high priced products and found the others lacked the bass dynamics (slam) and very fine details of these

Check them out - despite their apparent complexity, they are pretty easy to build

Yes power cords can make a difference. But which ones? The only way to know for certain is to try them in your system. 

Consider going to THECABLECOMPANY.com read about their lending library. 

Also see  JPSLABS .com  Their cables are excellent. 

Thanks for the input. I’m going to try something I’ve never done...go backwards after a tweak, try the monoblocks again with stock cords. I absolutely hear a difference with sources, but with these particular amps I’m just not sure.
