I think you summed it up in your comment about the
power amp:
"Heavy as hell. Powerful. Cheap"
I see folks like you all the time putting together
systems from catalogs and going for the biggest bang
for the buck and ending up with the same problem
you're running into. We've all done it!
You are not going to get great bass from a cheap
turntable.
What's it mounted on? It really depends on what you
want.
Where do you see yourself heading? Do you want
holographic imaging, high resolution inner detail, or
do you want to shake the house with warm bass? On a
limited budget?
You don't need all those watts so stop falling for
the numbers. Remember "heavy and cheap"?
Let's know where your head's at.
