A great interconnect between Soulution 751 and 725

In my view, your best upgrade is to take advantage of your components' balanced design and connect them using balanced XLR cables.

The quality and transparency of the Soulution components are one of the best in high-end audio so that lower quality cables would bottleneck its performance. I suggest starting at least to the level of Siltech Classic Legend level - this is what I own and my electronics are near the Soulution 3xx entry level while the 7xx is their top of the line.

Siltech and Crystal cables are in the same league , I guess

@renatocomes , Take a look at Audio Envy.

Don’t let the very affordable price deter you, they are very good performers
