"We have yet to insert it into a system,
no matter how well-designed or expensive,
that didn't sound cleaner as a result.
The device is completely transparent,
introducing no sound of it's own
even though it has an active stage;
it's just that the rest of the system
sounds clearer, sweeter, better focused
with it than without it." −The Audio Critic.
