Testing Regimen

Before we get to our testing, we need to look through our reference collection for an audio source and amplification hardware to see or rather hear what these speakers have to offer us. 

Below is a list of the components we decided to use for the listening tests:

Pre Amp: FSA Mass Preamp

Power Amp: FSA Big Joe IV 100 Watt Mono Blocks

All Cables: JPS Ultraconductor 2

Player Software: Foobar

Media: Free Lossless Audio Codec (FLAC)
