I traded up from the 300cx to the 400cx within 24 hours of purchase simply because, upon home audtitioning both amps, there was a discernable improvement to the dynamic range and detail retrieval from my Thiel CS6s.
That was back in 2002 and I have no inclination to change this system (KCT preamp by the way CASTed to the 400cx).
The CS7 has a similar load and frequency profile to the CS6.
To my ears there is a real difference afforded by the additional power, and this is apparent even at low listening levels.
Hope this helps.
