There’s a super clean ‘93 GFA 5800 available now that I’m seriously considering. I will for the time being be using my Cambridge AXR100 as a preamp. It turned out to be pretty...

    RS4 speaker stands?

    First time poster and new owner of a great pair of RS4's. I have seen a lot of pictures of either rs4 or rs4b's that are slightly elevated. My speakers do not have the stand. I have also read in an old brochure that the stand was an option. My question is does this have a big impact on the...
