Hi All, I picked all this up some time ago but I already have a great pre-amp so is this worth building? It came with all the bits to complete the two pre boards with headphones out.

Have you searched? John Brodskie (sp?) sells these boards along with the documentation. You could contact him and ask for some help.

Sorry I was not detailed in my question. I did a lot of research but I'm trying to find those who have built one to tell me how they sound.

I have built two, they sound very nice, well worth building.
From my experience the Aikidos work well as a headphone amp for high impedance 'phones and SOME low impedance 'phones. It's not entirely a question of impedance value. E.G. AKG 701s don't work that well with Aikidos I've heard, but might with a version based on the ECC99 tubes in the picture.
The two boards at the bottom of the first picture are mono line stage/headphone capable amps. one or the other, depends how it's configured. These would make a great line stage or HP amp (see proviso above) and the Janus regulator would be good for powering them. I think this is the Janus with the built in rectifier, filters and filament reg.
Yes, most definitely will the Aikido and Janus make a good sounding line stage. Tube dependant of course. It might even surpass your "great" preamp. I lean towards the Aikidos with 6DJ8 for a clean, fast sound. 6CG7s (a nine pin version of the 6SN7) will sound more tubey, in my experience.
