Description

Stage 2 – Wow!

Stage 2, takes the performance into an entirely diffierent level.  This is an upgrade service for any of the Cambridge Audio Azur 3xx evolution of integrated amplifiers, including the very first edition.  i.e. this is suitable for the 340A v1, 340A v2, 340A SE, 350A or the 351A. You send us the amplifier, maudifi upgrades it and returns it to you.

In addition to the improvements offered by the Stage 1 upgrade this maudifi upgrade adds more detail and delivers greater spaciousness / openness to the soundstage.  The clarity of voices in particular will surprise you.  After maudification (made-up word alert), this little belter will produce music close to the level of a high-end amplifier, for a fraction of the price.  Maybe even better than some.  Please see previous feedback.
