How much do I need to spend to get a preamp that sounds better than no preamp?


Hello all.
I'm using an Audible Illusions L1 preamp and I think my system sounds better when I remove it from the signal path. Oppo BD105 directly to SMC Audio DNA1 Gold power amp. I have read that there is level of quality you need to hit before there will be an improvement in sound. I can't seem to find what that level is. Any ideas?
Thanks in advance,
Ben

You make no sense, can't see the forest through the trees, as usual.

Like I said:
"We have the voltage from most sources at more than >2v.
Most poweramps only need less than <1.5v in, (some even 0.5v) to make them give full wattage output to the speakers." 

There is no debate at all, as any **** can see.
