I know many have newer models with these ribbons but I just ordered them for my FF3 SRE to replace the long BG ribbon and am curious on what to expect besides the more efficient drivers. Hopefully they will arrive next week and I am excited to fire them up, I am in dedicated room with Sonic Frontiers Tube Pre, Aragon amp for mids and tweets, SOTA table and Lexicon Multi. Thanks for any info, opinions or hints. Cheers
