I have been enjoying the original Pico for over three years now and it’s a great portable amp which I have no plans of ending our relationship any time soon. Knowing first hand the overall quality that Justin Wilson, owner of HeadAmp Audio Electronics, puts into HeadAmp products I decided to sign up early for the Pico Slim to reduce the size of my portable amp and see if going with a digital potentiometer would make a difference for me. So I became interested to sign up to the pre-order and received it about 11 months later, I have been using it now for a few months (5/14/09 received 04-19-2010). Sure that seems like a long time to most people but in the beginning this was a concept that moved to a prototype and finally went into production, so this long wait time should not be the case with normal orders, but I have to say that this might be my last venture with pre-orders.
Contrary to what others have written, I like the overall performance of the original Pico more to my liking, although there is a size difference but not a problem for me and the channel matching difference may not be as good on paper but very difficult to notice a difference unless you listen at extremely low levels. Without further delay let’s discuss the Pico Slim.
