I have owned the RS-1B for a long time and I had used Audio Research gear and it sounded very good. Several years ago, I bought a used pair of IRS Betas. These speakers put out a lot of bass, in fact too much even with the proper adjustments, it was just too much. I got an Accuphase D28 digital equalizer and it was magic after that. I am using an older pair of Krell KMA-200 on the bottom and Sonic Frontiers Power 3 for the top.
I have refoamed all the woofers recently. It was not particulary easy to do, but the prospect of having to spend $165.00 each or a total of $1320.00 easily made the decision for me.
If anyone is considering buying and IRS Beta or RS-1B, one does need to check the foam surrounding the woofer for cracks.
