Aether Audio Black Box or Nuforce Magic Cube ???

Well, I guess this filter is system dependent. I have the same amp as Ozzy - Pass 350.5 and prefer by large margin SCSS. With no filter I couldn't hear any big sound difference - placing filter I got huge 3D, very extended low frequencies, more dynamics and more transparency - you can see deeper in the stage. IMHO this magic cube is one of the best bargains on the market right now. If you can afford and place new Synergistic Galileo Speaker Cell in addition to cubes you will start to rediscover your complete music collection again...

Hi Ozzy,
You are doing right thing. It seems that SCSS filter is not for your system - otherwise you should hear very easy a big sonic difference right away. I think that right filter choice depends on amp-speaker interaction. I have electrostatic speakers with transformer based crossover so maybe that is the reason for different sonic results I got comparing with your results. I would like to ask you a question: How would you compare your Morrow speaker cables + Magic cubes vs Apex alone please?
Thanks
