Yeah, It looks pretty similar to the PARASex - both are based on the 6dn7. The new version is single chassis, whereas the old PARAsex was dual monoblock. What really sold me on the new SEX kit is there is no need for a preamp, which will require a high input voltage and it can be used as a headphone amp. BTW, the PARASEX kit was my first DIY project ever, and it is still running flawlessly. I hope the new SEX kit holds up as well.....Colin
