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

Thank you mrdecibel, and that's exactly what I post  "system (impedance) match" whether it's direct or with passive, which today is more the norm than the exception.
 There are just some here that are protecting their interests, like a dog with a bone.

Cheers George

Like mrdecibel said, the perfect world doesn’t exist.

Don’t cheery pick mrD, a perfect world does exist if the impedance’s are good, low output and high input (>1:10 ratio), and in most cases they are.
Go away now, you are so annoying.

You really have lost it, as I said 10k pot has at worst output impedance of 2.5k, a 1:10 ratio of that is 25kohm, so any amp with >25kohm or higher input impedance will be fine 
Please go back to school or stay off the *****, it’s effecting you really bad, seek help.
