An alternative would be to buy from a company like Decware or Quicksilver which offers a 30 day money back trial period.

I tried out Decware's ZSLA-1 preamp/attenuator this way and all it cost me was the $15.00 shipping charge to send it back.

As a side note, it turned out to be a real waste of time and $15.00 because I really didn't get to get a good feel for this product because, out of the box, it produced static in the left channel and I sent it back 3 days later for the full refund.

I live the life I love and I love the life I live.
