Is it important to long demo or own HIGH END gear to have a fair accurate view about it?

As a manufacturer we advise people that if they do not hear a significant difference within one listening session - probably within 5 minutes, then we will pay to have the item shipped back to us no questions asked.

@noromance - we want you taking our gear home to hear in your system.  We can show you the differences in the various systems we have set-up but you need to hear our components in your system to make your best decision always.

If you don't hear the differences almost immediately, then just send it back, no need to wait days or weeks.  We love this hobby and what our customers to always feel happy and that they make the right choice for them.  No questions asked.
