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!

I'd like a recommendation for cables that make Johnny Cash sound like Hip-Hop.  Just can't get there.  

Point being, I can see cables affecting tone.  But the speed of light is what it is.  The closest you could get would be whatever frequency range you associate with "fast" could be emphasized. 
Cables will not speed up your system plain and simple.

In terms of a what a good cable will offer - more inner detail, air, extension, tone, and dynamics - NOT transient speed. That said - I’m a big believer in silver cables. I use audiosensibility signature line.

Your digital front end is where you need to focus - the DAC and streamer/transport are absolutely critical for transient fidelity and speed/timing (PRAT). This is where you should be focusing.

The major characteristics of digital as you move up the chain are in regards to timing, and jitter. This means : transients, PRAT, staging, imaging and detail. Simple changes like using the i2s input of a DAC will help in this regard. The power supply to your digital gear is very important as well. 

This is how you will be able to optimize around your amp (assuming it can ever be "quick" enough for your needs)
One reason why manufacturers and audiophiles cryogenically treat cables 🥶 is because they sound faster. They also sound smoother and more musical. 🎶 I would go as far as to say if you’re not cryoing your cables you really can’t compete. In fact everything should be cryo’d. No, it doesn’t make the electrons or photons run faster, it’s like a perception thing. 😳
I had the Speltz Anti Cables in my system for about 5 years. Previously used MIT 700+ and it was like a cool Canadian front came through with the Speltz.
I then switched to the Mogami cabling and I heard what was missing with the Speltz. Signature of the Speltz is mostly aimed at mid treble.
The Mogami (inexpensive but excellent cabling) brings in more layers of the audio spectrum. Perhaps you’re missing detail and mistaking this for sluggishness?
Both cables are cheap enough to try.
Ok, I'm being pulled back in.

@AG-  My dac has a separate power supply is r2r and uses 4 -12at7 gold lion tubes and me thinks it is pretty tits.  I've been on a deep, deep....very quite deep dive on transports the past few weeks and agree this area of my system can use a booster seat as I stopped using a cd transport some years ago. 

@tweak1- pretty sweet that you were able to goose up the prat factor so much with Wire World Electra 7 PC's- I definitely want to try those cords and am on the hunt, thanks for the tip.  

@arro222- Maybe?  However, my body will usually gyrate in one way or another if the tempo is right. In some of my research, I think all of my gear will likely benefit from tweak1's suggestion of  Wire World Electra 7 PC cords (nice science that makes sense to me and I may spring for the silver edition)  the Snake River Audio Boomslang and the cables from Audio Envy look enticing as well.  I've never been one to focus on cables TOO much and am cautiously wading into the murky waters of audio cables.  I haven't looked at the other suggestions yet but will in time.  In my opinion, my cabling is just decent, but I know for sure they are not delivering all that may be possible therefore can be improved upon and maybe just enough for what I'm after...maybe.   

@geoffkait-  I didn't know cryo'd cables made things sound faster- thanks for the tip.
