High end stereo preamps? Worth it?

certainly, awesome very advance expertise you share herein. Soooo much brain energy being deployed.  This is complex stuff requiring many advanced degrees.

speaks to a need to improve the marketing efforts of high end hifi devices.  Basically, a large number have no clue what they are buying. They are comforted with expert reviews that seem helpful, and spending more money for incremental perceived value. Choosing a preamp is not easy!!! Marketing materials are horrifyingly tough to make sense of.  As long as boxes are built like tanks, weigh more and look pretty.

There are those who don’t believe that a top notch preamp can make a difference. To them, they haven’t heard the difference to make it worth it. Same goes for all bits are bits and cables are cables. Fine.

When you actually do get to hear the difference in your system, everything will click. I happen to love certain well executed integrateds but in my room, my speakers, my cables, etc a fine pre and a fine amp surpasses.

In a blind test no preamp can improve upon no preamp.

That’s an interesting claim. Have you actually conducted such blind tests? If so, please provide details and include the other components used in the test system. Then perhaps we can tell you where you are going wrong.

A great pre-amp can improve the entire system.  Especially in hi-end systems.  It was a day and night experience to drive my power amp with my DAC vs a matching pre-amp.  The power amp has such a low impedance that the DAC literally collapsed on it.  The DAC was never able to play loud.  The pre-amp on the other hand can drive the power amp until the speakers melt. 

Some more really excellent posts about how a quality Pre amp with system synergy absolutely enhances an already fine rig.  But to my point about not being able to site examples of science, I guess I meant that it is not easy 'to measure' the difference.   Nay sayers seem to stick to this defense; 'if you can not measure it, I can not hear it' and 'bits are bits' etc.  And, quite possibly, they can not hear it!  To me, measurements are important, but hearing is believing.
