For the amplifier to be stable, you need a load on the output stage at RF in order to damp any oscillation stimulated by induced RF. The load is usually a Zobel or R-L or both. What Naim did was to factor the cable impedance into the design of the network. The advantage of doing that is eliminating some passive components between the output stage and the loudspeaker. But in order to take advantage of it, they need control over the cable impedance.
With Spectral + MIT, the Zobel network is in the cable rather than in the amp.
This isn't bad design, it's just a different way of approaching the problem, by looking at things as a system.
