I recently changed the internal wires (which is like 20awg ?) of the Nenuphars with Vhaudio. I am using KLE banana plugs on the speaker end but after break-in the sound is just so much better and fuller. My rest of the system produces very detailed and lively sound (due to Lampizator DAC) and hence some recordings that has stridency or hard edges present has mellowed down without loosing anything. All in all, the upgrade proved every bit worthwhile. While the VHAudio upgraded wire with ofc copper conductor sounds as good as it does, I am tempted now to upgrade to even better wire, maybe silver. It looks like the internal wire might be the greatest weak point of this speaker depending on the rest of the system.

@ricevs I would love to try some of those purifiers….

If you really want to get a big boost then you need to solder the internal wire directly to the voice coil wire......and bypass the banana connection altogether......costs you nothing. Mundorf has some new wire called Angelique.....that I will be playing with.....it is an alloy of copper, silver and gold that they have been working on for a long time. Probably sounds great inside the Nenuphar and soldered directly to the voice coil wire.....of course, for those even more experimental....you will eliminate the WBT binding posts and clamp the wire from the voice coil wire directly to your speaker wire using Nylon hardware. I will have nylon hardware for sale real cheap on my site soon for this purpose.

The one time free pair of Muisc Purifiiers is gone.....the person who got them knows who they are.....sorry for you slow pokes....he he.

Anyone can "try" these Music Purifiers......I give you 30 day money back.....and in fact, if you do not like them and want to return them for full refund (including shipping)........I will also send you $10 to mail them back.....so you lose not one cent.

Debjit I did used solid core siltech wire to replace the internAl wire of  my Norh Speakers. The improvement is so huge.

@ricevs i wasn’t looking for a free pair. I would really like to try it out if they aren’t exorbitantly expensive (I don’t really know what they the cost). Anyway, I could have easily hardwired the wire straight to the voice coil but didn’t do it for two reasons

1. I want to first evaluate the best wire and experiment before soldering/desoldering things. I don’t really like hit iron touching the voice coil often.

2. I have been contemplating v2 driver upgrade.

 

btw, I am aware of the Mundrof’s new Angelique series. I went to Partscon couple of days back to get the 15.5awg Mundrof Silver/Gold for a power supply project where I saw those.
