Hi Barry,
I will not be doing any more modifications to my system in the near future. I am in the process of building a pair of Gradient SW-63 look alike using two Peerless 830669 drivers per side. I chose the Levinson HQD for my avatar because it is my dream system but I cannot even afford a tenth of it.
On another note, I noticed that you are in Essex. I bought a lot of equipment from Chew & Osborne in Epping. Nick Osborne and Ian Purkiss were the soul of the store, fantastic chaps, very sad of its demise.
Cheers,
Horacio
