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

Since you have the Ayre there for use in your system, the relevant opinion is your's. 

We await the results of your evaluation.
@georgehifi When you continue to cherry pick comments from an article that clearly favors active circuitry its disingenuous to say the least. Are you trying to make Nelson a liar??

Repeating it all over and over does not make it right- it just makes it trolling.
Ralph I’m not trolling, you can stalk me all you like, would you like me to start returning the favour?, you "try" to present facts your way, and I’ll do them my way, with whoever/whatever proof I have.

George, sorry, you're not fooling me. Endlessly spouting the same thing over and over, especially when you know you are leaving out important facts, is one way trolling is defined! The result of trolling is that someone has to correct your misrepresentation- and then we go on and on, around and around. That's classic trolling.
If you are such an admirer of Nelson then don't make it as if he is saying something he isn't. That seems disrespectful to me at the very least.
