The heart of my system is really the Tetra 606's. If there is one piece that just speaks to me in everything I want form a speaker, this is it. Being a bass player like other famous bass players who own these speaker, I completely get it. It just gets bass right as well as everything else. Paired with these is something I have never done before, I used the same brand Herron Audio for most of it. I first bought the phono stage and was so impressed I bought the Line Stage and in turn two weeks later order the mono blocks.
