I have been very happy with the Symposium Ultra platform, I use them under my EAD Pre/Pro and my Levinson 37 transport they come with coupling blocks or for over the top performance try Nordost titanium pulsar point or the symposium rollerblocks in combination with the platform.You can track them at www.symposiumusa.com ask for Peter He is great to work with and www.nordost.com for the pulsar points
