TuneBlock Series 2 SE {Set of 3}

Manufacturer's Description:

At $299/set including tungsten carbide bearings, our flagship "Special Edition" (SE) TuneBlock represents the culmination of over two years of research and development. Building on the award-winning TuneBlock XT, the SE takes the XT's best-in-class performance to the next level.

The SE incorporates the following refinements:

  • Mass – Each TuneBlock SE has more than twice the mass of our standard TuneBlocks, a critical factor in getting the best performance possible.
  • Improved Bearing – Our new SE tungsten carbide bearing has 50% more mass than our standard tungsten carbide bearing. In addition, SE bearings have been cryogenically treated for increased hardness and molecular conformity. We are the only manufacturer to cryogenically treat bearings.


  • Recessed Base – A 2mm recess is machined into the base of each SE block, further isolating the block from your shelf or table. This feature minimizes a potential source of performance loss.

By incorporating proven high performance materials and an ingeniously simple design, the TuneBlock SE represents the pinnacle of footer performance regardless of cost. For customers who need the absolute best, the TuneBlock SE is it. Each TuneBlock SE measures 2.5" in diameter and is 1.5" tall. Exclusive high performance tungsten carbide bearings are included.

Boston Audio TuneBlocks are our award-winning line of equipment supports. Made from the same grade of carbon as our acclaimed record mats and finished with the same proprietary sealing process, TuneBlocks offer a level of performance leagues beyond their price. Completely expanded and refined in 2006 with the launch of the Series 2, TuneBlocks now offer more performance and application options than ever.

TuneBlocks utilize the uniquely low acoustic impedance of carbon graphite to efficiently drain mechanical energy from audio components, while simultaneously isolating the component from the shelf or table supporting it. You'll notice reduced transient smearing and increased resolution through the reduction of the components' noise floor. TuneBlocks also improve localization of instruments and create a wider and deeper sound stage. Use TuneBlocks with CD/DVD/SACD players, DACs, preamps, amps, turntables and even speakers ("S" model) to reveal detail and clarity you haven’t heard before. Unlike some other footer products, TuneBlocks offer gains anyone can hear without leaving a sonic signature of its own.

"...the tonal richness of the music eclipsed the previous standard set by the combination of Stillpoints on a Symposium Acoustics Svelte Shelf."
Rick Becker

Each block is machined from a billet of high purity carbon graphite (not molded carbon fiber) and contain between one and seven cubic inches of carbon, depending on the model. Once shaped, the blocks are finished using our proprietary sealant applied with an automotive-quality spray finishing system. The stationary bearing is used as a coupler between the component and the carbon block. This concentrates the weight of the component into a small area, allowing vibrations to be more efficiently drained into the carbon block. Equipment does not wobble on the bearing like other designs.
