Keith, why do you need to use the "small signal amplifier"? I have more or less the same signal chain as you with the exception of the signal amp. When I called Paradigm, they told me the X30 did add gain to the signal - is that not true? Which signal amp are you using, cost, etc? Did you try the BK out without the signal amp? What happened?

Hi Dave,You are absolutely right in that the X30 provides the additional signal gain. You do not need to use the additional amp inline (Radio Shack SA-155).
I have a Denon 4800 (200mv signal output) that had to have the LFE output amplified before feeding the Carvin amp. When I subsequently purchased the X30 and dropped it into the signal path - I did not remove the SA-155.
There are times that you might want to use the SA-155 depending on your environment. If I were to introduce more weight into our home theater setup (4x12 platform, two loveseats, four adults) - I would likely need to boost the signal as we now have both the X30 and the Carvin amplifer volume set to maximum.
Another benefit is that the SA-155 allows me to boost and enhance the BK output when listening to music. With the X30 and Carvin volume set to max, I need to adjust the Denon volume fairly loud to produce any noticeable BK vibration from the minimal bass at 80Hz and below typically found in CD music . With the SA-155, I can increase the output such that lower music volume settings can produce significant BK response.
It's all personal preference - but you're right - the SA-155 is not a required component.
