What are folks using for the speaker cable with their Nenuphars ?
@debjit_g  I am using cables made by Scott Sheaffer. They replaced my Synergistic Research cables (which were also quite good).
Still haven’t built my pair, but I’d like to take another opportunity to suggest the tempo Electric solid core 99.99% silver in oversized Teflon jackets. That’s basically the purist, most conductive wire available in one of the lowest dialectic insulators. Other people may appropriately charge you for advanced geometry and terminations, but they’re not going to beat those basics no matter the price.

I replaced all the wire in my system with high purity solid core silver including all internal wire in my Coincident PRE speakers. Every step of the way things got more natural and refined. The tempo Electric wire runs all the way from my internal amplifier boards out to the speaker drivers. Not a touch of the brightness or thinness sometimes associated with silver.
Thanks @david_ten and @cal3713

@cal3713 what gauge and connector will you be using ? single or double run ? have you considered replacing the internal wire from the speaker terminal to the Neo 10 driver with the Tempo electric wire ?

Cal,
I’ve used various silver IC and speaker cable over the past 20 years. I’m currently using Ocellia silver cables the past 7 or 8 years. As with you I just haven’t heard the thin,bright or edgy sound supposedly attributable to silver. In fact the Ocellia is very refined, smooth, and organic yet quite open and nuanced. Exceptionally transparent/clear. Warmth rather than cool and sterile/clinical.

Interesting the improvement in your Coincident speakers as I know they use high quality 6N copper wire. Israel Blume (Coincident founder/owner) once told me he doesn’t care for silver. I respect his opinion but I’ve never had a problem with silver wiring.

IMO silver actually has a natural warmth (But not gratuitous).I’ve always been curious as to how my Coincident Frankenstein 300b and their Statement Line Stage would sound with silver internal wiring. But I’m very happy with both and left well enough alone.
