@stephendunn I have the 2020 version unpowered into the Bakoon dac. I see Mark Coles has now introduced an even higher model called the Evo, not tried yet. His LAN cable was the best I tried as well.


@toetapaudio NA is near to you and they have a 30 days hassle free in-home audition. I am using their Eno series streaming filter/cable, along with their Eno usb to great effect.

@dlcockrum  Dave, welcome to the thread. Thanks for sharing the video.

Advance congratulations on being a  Nenuphar V2 owner (soon)!!!

@rsf507 Thanks for sharing your impressions of the Refined Audio room. As you know, show impressions run the gamut and what is "best" for one is not necessarily so for another. Your impressions are valid...if you have thoughts on how Jon may have improved his room, shoot him an email.

Some audio friends of mine were not at all impressed by the 2019 Axpona room and seriously questioned my choice in the Nenuphars way back then. : )
