A mistake spending too much on amplification?

I was wondering if I screwed up by spending too much money on amplification? I have been upgrading my amp/preamp for awhile now (I started with a CODA Unison, then upgraded to a McCormack DNA-125 and EE Minimax, then to a Herron pre, and now mating that with Sixpacs). And, although there are subtle improvements, I am not hearing any night/day improvements, even when I go back to the CODA. And the CODA is much cheaper!

Does this mean I outpaced my speakers? Kind of like putting a supercharged turbo engine in a car with bald tires? Speakers are VS VR2's and Soliloquy 6.3's. Anyone have a good estimation on amplification costs relative to speaker costs? Sell the better amplification; use the money to buy better speakers?

The behavior of either a piece of electronics or of a loudspeaker can be described in terms of its "transfer function". The transfer function is the sum total of everything the device does to the signal as it passes the signal on.

A purely electrical signal consists of variations in but two domains: time and magnitude.

But a loudspeaker's output has variations in five domains: Time, magnitude, and three dimensional space.

So a loudspeaker's transfer fuction is far more complex than that of a purely electronic component, and the loudspeaker therefore has much greater inherent opportunity to screw things up (which it takes full advantage of!).

Cutting to the chase here, in my opinion speakers make the most difference.
