and I have to agree Sweetie sounds pretty darn good on my HIP Heresies without a sub. But there was something almost undefinable nagging at me. It didn't sound bad. It just wasn't lighting me up like I was hoping it would. I think adding a sub might be one of those things you don't miss until you have it. Then you realize you needed it. We'll get to that later but for now why wasn't I more enthusiastic about the overall sound? Again, it didn't sound bad but there was something I couldn't put my finger on that just wasn't there. At this point I should tell you I used to be something of a cable denier or skeptic. I didn't think interconnecting cables could make a big difference once you reach a level of competence and you're using "adequate" quality cables. I realize that, like so much around audio equipment, terms like "adequate" are highly subjective and I'm opening myself up to criticism. In fact, I'll probably be excoriated-if not excommunicated-because I will soon be offering some cables for sale in the Garage Sale section but in my humble, admittedly biased opinion upgrading from my entry level cheapos to some good quality Audioquest interconnects delivered an immediately discernible improvement in bass on my Heresies without a sub so I can now confirm Sweetie's bass is "mighty good".
