powercord for a Symphonic Line La Musica


I am looking for a power cable for mijSymphonic Line La Musica integrated amplifier. My CD transport (CEC TL51x) and DAC (wadia 12) both use a NBS dragon fly power cables, I also tried one with the amp but I don't think it is a good combo. Maybe I am expecting to much since the power cables on my DAC and transport gave a real improvement. Should I expect less of an improvement for my amp or should I use an other power cable for my amp. I am looking for something that doesn't break the bank. Brands that I can buy here are NBS, Shunyata, KEMP, Nordost, Cardas and maybe some other brands. Should I move futher up in the NS series? I didn't like the mine/serpent much.

Any advise is welcome.

Thank you for your reply Rich,

I was thinking to spend up to €400,- for a cable. As a reference I paid €200,- for a single NBS dragon/fly. I have been looking at 2nd hand NBS cables but I am a bit confused. There seems to be a NBS, monitor and a active series but I don't what is the difference between them.

And yes I am very happy with the Symphonic Line amp, was able to buy it for a really good price otherwise it would have been way out of my price range.
Check out the new Reference series of PCs from Tek Line Cables. I am using both the microReference Xtreme and "The Reference" if you can afford $750 PCs, The Reference would be my recommendation
lots of good pwr cords in your price range--400---1500 dollars---good luck you really have to try cords in your system--let them break in at least 2-3wks before making any judgements

As far as I could tell I can buy Tek Line at the their website and nowhere else. I prefer to buy a cable at a dealer new or second hand because I would like to try the cable before I buy it.

How good is a Shunyata Copperhead compared to a NBS dragon/fly? I have read mey good things about the Coperhead, but I am a bit reluctant to believe reviews.
