Ultra rare, hand made in Italy cables. The X-Solution is not their top of the line but when compared to some of the top of the line cables from its rival brands, it might as well be. Musical presentation was vividly detailed and fast. Bass was a bit tight for smaller bass drivers but with larger woofers, it was “thumpingly good”. It’s formula of using copper and silver and excellent EMI/RFI shielding undoubtedly played a big part. We highly recommend this cable. Compared to a similarly priced used Nordost Frey XLR cable we have for sale also, it was a no-brainer. The X-Solution was a clear winner by far.
