Thanks David for the advice.

ricevs, I’ve been there and done it 30 or so years ago. I agree it does make a difference direct wiring. As a Cube dealer I’m not going to recommend as this would inevitably disqualify the warranty. It might be possible to specify when ordering but doubtful? Manufacturers make compromises for commercial reasons.

I’m not convinced about Bybee though, I have some but not tried with Cubes. 

@ricevs what is this super wire ? Any link ? I have contemplated changing the internal wire of the Nenuphar to a better solid silver wire but just didn't get to it. The internal speaker wire looks a bit flimsy and think a better wire could definitely benefit.
 

 

 

Btw, I have been using a pair of Fidelium speaker cable for some time now with great results.

Also have been playing with a pair of SR latest CTD (Carbon Tuning disc) - placing a purple disc on the speaker cable did not yield any change with the Nenuphar, which is contrary to what others have reported with speaker cables. Might move them into the speaker, near the banana post to see if the results are different. 

It is not just one thing that makes a differerce....it is everything you do. better wire, removing the sound of the jack connection on the speaker, removing the sound of the WBT binding posts, adding the enhancment of Ground Enhancers and the Bybee thangs.....it is five things.....

You just change the wire and you only get one out of five. I have not played with the Bybee thangs but I am getting a pair in shortly to try on a single driver speaker here.......but I doubt that review and this one are wrong:

He only heard bass changes....not mid and treble.....but he liked very much what he heard.

I have never liked silver wire. I find it too silver sounding.....forward and bright. I have straight wire bypassed WBT rca connectors......and the silver ones sounded "more detailed and forward" than the straight wire. Maybe some dull system could use this coloration. Right now I am using the 14 gauge VH Audio wire that is cryoed OFC stranded wire in foamed teflon.....I remove the outer clear teflon cover. Sounds really great.......I am sure there are better wires.....but which one?

You can see a crossover I made for someone that has this wire and also the quarter inch nylon bolts and nuts to secure his speaeker wires (Fidelium cables with biwire adapters.....will have more pics of his system up later today). Be sure to scroll all the way down the page to see the latest large pic of the updated crossover. Incredible speaker.....out of this world great

I will soon have pics and description on this page that shows an open baffle system using the top of the line Lii Audio drivers with added super tweeter.......and even more ideas and pics down the road.  Please bookmark page and follow along.  I think you will be amazed and what can be done......and for so little..

@debjit_g I too have been experimenting with the Carbon Tuning discs.  The purple ones placed on my Shunyata Alpha V2 speaker cables brought the highs more forward, irritatingly so for some recordings.  (I've certainly forgotten about irritating highs with the Nenuphars, something much more common with the Voxativs I've auditioned).  But on some recordings I kind of like the forward highs.  Be interested to know if you find another application that makes an overall positive impression.

And I'd like to add a follow up to my comparison of the Enleum 23R and the Decware Zen Triode 25th Anniversary amps.  It seems that the 23R was not burned in all the way when I wrote my original review.   It has opened up considerably more since my last report, better dynamics, even more detail, especially in the mid range and mid bass, and more air.  And richer tone.  To my ears it clearly bests the Decware Zen with every type of music I play.  And especially, as I mentioned before, with big orchestral works which expand the walls of my listening room as if I'm inside some virtual reality headset.  It is hard to believe it all comes out of that tiny box.

@ricevs  One has to take what you say with more than a grain of salt.  Your High Fidelity cables are living proof of your expertise.
