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

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.

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.

This is an easy one for me, being somewhat of an Anglophile. London Reference pickup, Helius Omega Silver Ruby arm, Townshend Audio Rock turntable, Ear-Yoshino Acute 4/Dac 4 CD/SACD player, EAR-Yoshino 912 pre-amp and 534 power amp, QUAD ESL loudspeakers.
