Musical Fidelity A1 - Sugden A21, how do they compare?

Many Sibelius owners have asked me how the Musical Fidelity and the Sugden A21 compare, and I was very curious too! Both amplifiers are Class A and have a similar outputs and feature sets. However, the Sugden A21, with a phono input is more than twice the price of the Musical Fidelity A1 at 3,400EUR versus 1,600EUR for the Musical Fidelity.
