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.

Everything has to be taken with a grain of salt.....including what you say. For instance, I am not the Rick Schultz of High Fidelity Cables. I am the Ric Schultz of Tweakaudio.com. Even though you are wrong about this.....you are still worthy. You are beautiful....I love you.

All you have to do is to try something and listen to know whether it is "grain of salt" or high class organic honey. Sweetness rules.....I kiss you all so sweetly.

@ricevs My apologies for the mistaken identity and appreciate your understanding.

@stephendunn since you mentioned the Enleum, I just looked back the posts and realized that I have never posted about it. Recently I snagged one from a local audiophile buddy who was using it as a headphone amp. He has never hooked it up the speakers. I was not very confident that this tiny little amp can do any wonders compared to my modded LM SET. Well, never in the past I have been so wrong about audio the first time I have hooked up my system to the 23R. Just before I snagged the Enleum, I bought a new pair of Psvane ACME 805 for the LM and I had only played about 10hrs before the 23R took its amplification duty. So far, I have not turned the LM, neither I have the urge to do it. I will probably compare at some point but I can say that the sound from the Enleum is very satisfying.

I had a SR orange fuse laying around and it took the Enleum a notch or two up. Now a SR purple is on the way.....man, this hobby is just nuts :-)

I will update on what I find out on the CTD...
