Anticipating that I would upgrade my Krell Studio DAC to a Denafrips (which doesn’t come with a power cord), I decided to buy the power cord first. That way I could break it in before the upgrade and my DAC comparisons would be apples-to-apples. I saw a review of some power cables from Passion For Sound on YouTube. The SUPRA LoRad 3x2.5 Power Cables (eBay) were about $100 for 1.5 m. I wasn’t prepared for how much improvement they made to my digital playback. I tried the cable on my Rowland preamp and again was quite taken back at the improvement (I bought another of the same power cable). I’ve owned that Krell DAC for 30 years and for the first time, I actually like my CD collection. I decided to keep the Krell. I just now checked eBay and those power cables are even less expensive now than when I bought them. They are the most cost-effective upgrades I’ve ever made to my system
