Best all British, except cables, system you heard or can think of.


I haven't heard such a top level system. Analogue source only.

Bass for the Quads I left out because that HAS to be American---the GR Research/Rythmik Direct Servo-Feedback OB/Dipole Sub is the only way to go! If it has to be British, the Gradient dipole sub will do.

Some German and French can be bright, I think.
bdp24, why not REL subs ? Should do well with Harbeth, but maybe not with QUADs
Mapman, I don't tolerate yellow badges. Please..
inna, the GR Research/Rythmik OB/Dipole Sub is a completely different animal than are sealed and ported subs, even really good ones like REL’s. It works well with all loudspeakers, but especially dipoles. A dipole sub with a dipole speaker, see? Siegfried Linkwitz designed his dipole speakers with an integral dipole sub similar to the GR Research/Rythmik, but without the benefit of the latters servo-feedback system.
