To pre or not to pre


Do I need a preamp?  I primarily listen to digital files from an Aurender server through a Mytek Brooklyn straight to my Pass amps. Some tell me that regardless of the Mytek control capabilities I should get a preamp.  Seems unnecessary to me.... am I missing something?

My biggest issue with the Mytek was it would respond to a static discharge by going full volume.

But I liked using it directly compared to some, not to others.

The Mytek Brooklyn was more transparent than run through a Parasound P7. Slightly so.

With my new Luxman set up, I can't tell a difference and prefer the convenience of the integrated's source selection.

So absolutely required, no.  Maybe a safety issue though! ;-)

If!!! you love the sound of your Mytek and have enough volume from it, why color it, reduce the transparency/dynamics with a preamp?
