You can build your own for under £800 using PCBs from
DiyAudio /
DiyAudioStore, chassis from Modushop, etc.
Here is a thread I started after I finished my Pass F5.
I totally understand if you want something already finished though. It's a lot of work, but a lot of fun to push through one of these builds. The funny/sad part is I am considering selling my Pass F5 amp and BA2018 preamp (designed by a Pass employee) and I haven't even finished the preamp. The problem is the amp puts out a lot of heat, kind of like having a toaster on in the room the whole time you are listening to music. Might not be a problem in some places where you heat year round, but in Valencia it tends to mean having another fan on, or worse, A/C.
