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

I don’t understand why you keep posting that.
Because it was the original balanced power supply direct coupled (matched) complimentry jfet buffer that Nelson designed for the Lightspeed.
Afterwards it became (I believe the cruder) unbalanced supply re-configured capacitor coupled p channel jfet buffer (didn’t need to be matched) for the B1
Once again go away your stalking, also calling my product "thing"? you really need to see someone.

Cheers George
If you play digital, the MSB DAC can drive any amp, using passive analog volume control only.
