Amazing improvements can be achieved using the Speedblock and Bigblock on electronics to reduce the mechanical resonances in transformers, power supplies, chassis's ect...
The effects are greater transparency, better image focus, wider & deeper soundstage and lowering of the noise floor.
The Acapella aluminum couplers work excellent between the Block and component to transmit the energy. We recommend that you start optimization at the end of the chain (amplifier) first.
