I’ve got I special Rogue two-tube VT99 preamp that I will probably never sell. I think in the case of the Sphynx (being a hybrid tube/class-D design), it has to compete in a rapidly changing and improving segment with saucy new technologies (GANFet). That said, I pair my Rogue preamp with older Ice Power Class-D mono’s, and I also own GANFet monos (driven directly by a streamer), and honestly I initially couldn’t pick one over the other, they each have their strengths and weaknesses.. both are great, but I chose the Rogue Pre paired with my older Ice Powers as my daily listeners because I like to roll, and with the right tubes the top end is more detailed.. yet organic. Some slight noise might be a small issue given a sensitive speaker, but not in my case. It’s very quiet from where I sit.
I think many buyer’s might worry about older class-D products.. whether it be Hypex or Ice Power. Also, selling audio gear in the months leading up to Xmas is a bit challenging given the potential buyer’s wife may not like seeing a present showing up for them right before.. I think many may hold off a couple mos. However, I’d also bet there are people out there somewhere pining for an affordable Sphynx. Some people just want a reasonably priced vessel to roll what has now become a particularly expensive NOS tube inventory.
