Ok, so I just arranged the sale of the preamp from my practice rig and my new preamp is still enroute to me. So, I figure, I'll just suffer and use my DI as an interim preamp in my house. So, I take my passive bass and plug it into my LA Audio DI2 Mk3 and plug that in to my power amp. If you are not familiar with these DIs, they have no eq adjustment, they simply boost the signal. So, I was expecting the worst. I figured that I could always play my other bass that has the J Retro preamp if this experiment didn't work. Besides, it is a short-term fix to keep me playing while waiting for my new preamp to arrive. With everything plugged in, I turned on the amp and started playing. Wow! I can't believe it. This totally simple setup sounded really good. Its only flaw was volume. It is loud enough for me to play on my own, but there isn't enough signal boost to play with a drummer. I won't abandon the new preamp when it arrives. I still plan on using it, but I have to admit that it makes me wonder if too much eq is bad for bass. Maybe all I really need is the tone knob on my bass and no other eq. It certainly is food for thought.
