Recommendations for fast sounding cables


I've recently acquired a SEP amp based on kt88's and while it presents well in many ways it lacks the speed of my push-pull and ss amps which is typical.  Thus I'm looking for some nice and well rounded sounding speaker cables (non-biwire) and interconnects (single-ended) that excel in speed, tempo, PRAT, whatever you wanna call it to try to get some of the head nodding and toe-tapping back.  Transparency, detail, open soundstage are basic requisites as well.  I would also consider maybe changing out my psu umbilical cord, usb, and digital coax.  I understand that this will likely involve some or all silver in the makeup of the cables, and while I like a lit-up sound- an overly bright anything will usually get quickly replaced.  The budget is not high at $100-$300 new or used but may make considerations for something exceptional that fits the bill. I've gathered that some of the following may work- please feel free to comment on those as well, but I would also like to get some more suggestions.  Thanks!

Hate to say but you will never get what you are seeking with a change in speaker cables. Time to go back to solid state amp as others have implied or said. Save your hard earned money, sell what you have, and upgrade. Not saying SS is better. But for your situation, it may be better.
You might take a look at Speltz Anticables. The most ‘transparent’ cables I’ve personally experienced. And probably right in your wheelhouse re price. 
DNM Reson very coherent and balanced top to bottom.

What amp and speakers specifically? Wires may only be a partial bandaid if amp and speakers are not matched well.
Hey mapman- here's a subsequent post I put up with a bit more info, but with this setup in question out of the list would be JBL L100 Classic or Monitor Audio Silver 2 and likely Triangle Titus EZ with a Reisong A20. 

Thank you everyone for all the great suggestions thus far. In reading some of your comments. I now realize I should have qualified some of my statements and will first start with a list of my modest gear I am using for a better picture of what I am working with and some further explanation of my expectations.

The amp in question is a Reisong A20 that I bought new here cheaply on the Gon and was meant to be an experiment to see if I couldn't cheaply fill a void as I understand no amp can do all things which is why I keep a few on hand for synergy purposes. I've since upgraded the tubes to Gold Lion kt88's and some WE pre tubes. and run it with a Triode Labs pc. I may consider modding it someday as it is a good looking unit but I'm not there yet. It is surprisingly quite good and really isn't terribly slow with the L100 Classics which is 90db. I'm not here to start a flame war but I am squarely in the camp that prefers tube amps to ss for over 15 years and understand both have their virtues and non-virtues. I also understand that the most logical step is to get even more efficient speakers and will do that someday- but as I like to buy used, I've yet to come across a pair to bring home that I think I might like at the price I'm looking for. Since my suite of cables are quite competent though not awe-inspiring- I thought maybe I could gently help push the signal through a bit quicker by upgrading some cables in which all of my gear can benefit from- not just, but mainly the SEP, and really I'm not expecting miracles in the speed department. All of the recommendations thus far sound interesting and I will look into all of them. Please keep them coming, thank you
