Hello. I use since 1978 loaded with a Quad 405 and for 10 years in direct output of my computer and a sound card Sound Blaster X-FI, remisent nine for 3 years through Ebay-woofer-tweeter new medium of secondhand (copy remade in the usa) to cater to those looking for parts) .The sound is still as fabulous is the only forum that permetrait me to redo partitions bass guitar tuned !!! .Evidement The sound of L100 depends a lot on the amplifier with which it is used (and the listening room is also important). 405 being so transparent that the L100 remains neutral on all register.
Speaker also used in the recording studio.
The only enceite I could put at the same level are the Tannoy 38 (2 channels with built tweeter) but are more or at prices beyond reasonable
