Can't remember for sure and would have to take them off. They are screwed into the mfg feet in the bottom. Lector wisely uses only three feet so the player sits without rocking. The cones are supported directly on a BD Shelf which is supported on an air platform then a very well reinforced oak rack. I am sure others have different ideas about support and isolation, but this combination works for me. I view the support as letting the player do what it does with out disruption, whereas I think tubes and cables can be used to more actively achieve a certain "sound" whatever that sound is to you.
This is thinking out of the box. I put my tube cd player on a sofa cushion and everything improved the highs,imaging and bass response.It cost me nothing 'just used from an old couch I don't have anymore. Just kept a couple of the cushions.Lokks like old yellow foam used from old cars from the 70's interior usage.
BUT WORKS
I think a leveled player is important as well, so the sofa cushion intrigues me. I had the walker audio valid points and replaced with the Finite Elements cera pucs-very happy with sound. I do agree that power cord, line conditioner and interconects-balanced for me-are the foundation, and then, isolation. All work together with synergy and then, when it all clicks-along with a great cd player, preamp, etc, digital, well, finally sounds good. SACD does blow my mind. Not always the emotional connection that vinyl gives me, but a very pleasing, musical experience.
