Best Preamp - NO preamp... (?)


A few hours ago I decided to experiment and bypassed my highly regarded, excellent passive preamp and hooked up my PS Audio DSD DAC directly to the power amp.
There is no going back...
Every aspect of the sound has improved so dramatically that I'm simply blown away. I'm a bit shocked, playing CD after CD and I still can't believe it.
My phono stage has gain control as well, so it seems that from now on it will be disconnecting RCAs and plugging each in turn.
Since I usually do vinyl day or cd day (or week) anyway, the trouble seems totally worth it. Letting the cable settle in for a bit is not an issue.
Am I just crazy or are any of you doing the same?
Should I be concerned about damaging  the RCAs over time?
Thanks for your thoughts and experience. :-)

I almost always have two preamps in the signal chain
(opposite of what the op wants, instead of none, I add a second one)

My new preamp has has improved the sound of my amp by leaps and bounds. No question that using a preamp in this case is an improvement.
