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

Well said Erik, and probably what many others are thinking and don't want to admit.

Linear Tube Audio MZ2 with the upgraded power supply is around $1800. In my opinion it is the best bargain in Audio.
I've tried four different DACs direct and I've always preferred the sound with a preamp. 
I should point out that this idea of taste applies only when we're talking about reasonably well matched impedances. If you have a low impedance amplifier input a preamp may indeed be needed.

However given the modern high-current op amps in most DAC's, most can drive 600 Ohms. Easy peasy. 

Best,
