Looking for recommendations

As I continue my audiophile journey, my next step is speaker cable and interconnects.  I'm looking to bi-wire my Usher Mini-2 Diamonds to my Parasound A51, and to connect my Eversolo DMP-A8 as well.  Currently have a set of Blue Jean Cable speaker wires, and some generic XLR connectors for the streamer/amp connection.

I was about to pull the trigger on a set of Straight Wire Expressivo II Interconnects and a set of  Expressivo 3 IBW speaker cables (10 ft runs).  Cost is about $1600, so I'm looking for something in the same ball park.  Hoping to open up the details and soundstage even more (I'm impressed with the details I'm hearing now with this setup).  It's thanks to this forum that I bought the Ushers, and I'm looking for another great recommendation.  Thanks.
