One of the most popular combinations in audio is the Sony 777 and Rollerblocks. Here's a set up using the Rollerblocks on top of an Ultra, which further enhances performance for unparalleled enjoyment of CD and SACD reproduction. Notice if you will the Large Couplers deployed beneath the Ultra. Since the customer didn't need to use them between his 777 and the Ultra's top (he had Rollerblocks), they were put to use in this recommended configuration.
