Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure

@david_ten David, no I have not reached out to Grzegorz. In a hindsight I should have but most of the time these types of mods are not encouraged by manufacturers as it indicates a weakness in their products. Now that you mention, I will write to him and report back if I get an answer. Thanks for the suggestion.

@debjit_g  Debjit, I think he will be open and helpful. I would not be surprised if one (likely more) of their clients has provided feedback on wiring choices. You never know... something you happen upon might find application on their end.

They are probably at the High End Munich 2022 Show...in other words, it may take longer than usual for a response.

@debjit_g eager to hear what you think of the "music purifiers" and also very interested in your changing out the internal wire.  Want to hear more about optimum wire before making the leap.

To add to the wire discussion: I bought a pair of Silversmith Audio's Fidelium speaker cables on a 30 day home audition.  I only have about half the burn in hours they recommend (50), but I have to say they clearly leave my Shunyata Alpha V2 cables in the dust.  Clarity, detail, layering, depth, and maybe most surprisingly bass have all taken an engaging, totally musical leap forward.  They are 1/4 the price of the Shunyata Alphas--pretty shocking really.  Number of reviews out there.

I have the Fidelium as well. Clarity of this wire is in spades. I will also be trying some DIY cables out of pure copper (ofc/occ) after I have some understanding from Grzegorz (per David's suggestion). The good part is due to the low power requirement the Nenuphars don't need too much heavier gauge to sound good.

Here is the before and after
