Do you like the sound of your RF-5's? If so, you'll love RF-7's. []
I'll be interested to hear your comments on the RF-7's compared to the Forte. I had Forte ll's breifly........Heresy's breifly......Chorus's breifly.......all side by side with RF-7's. Amped them with tubes, solid state and pro-amps.......three different preamps......vintage, tube and solid state......and to my ears the RF-7's were much more to my liking for many reasons.
Of course it's just my opinion and my taste in music.
If you're happy.....and used to the sound of the RF-5's........you'll fall in love with the 7's. They do however, like a lot of power to make them shine.
My second vote would be for KLF-30's...........awesome rock and roll speakers. [Y]
