Mirza what makes you think that your massive Classe reference amplifiers are not dynamic?
The issue you may be having may be solved possibly by changing your source perhaps or cabling?
If you want to increase a system's speed and dynamics often adding footers can help tremendously.
The Spectral sound is fast and clean perhaps your system is too dark and that is why it sounds less dymanmic to your ears.
We would need to know the entire setup before making any positive recommendations, but we would look at what you are trying to accheive.
Older Classe gear was very warm sounding the Nagra is very uncolored.
