The concept of the EX-888.1 was even further perfection in the quality of music reproduction that made the success of the EX-888. The improvements consists improve the input stage and a number of crucial components for the quality of music reproduction including high-end connectors.The EX888 is an amplifier using KT88 power tubes and 12AX7/12AU7 tubes for pre-amplification.
We wanted to achieve with the EX-888 an amplifier with an exceptional sound that honours the legend of tubes but also benefiting from a reserve of power that allows easy association with the majority of speakers in the market. To achieve our goals, we used a proven pattern but with some unpublished parts (including a so-called "anode follower"), which allowed us to reconcile a low rate of reaction against (ensuring maximum power) and a very low level of distortion (less than 1% with a gradient odd harmonics characteristic of achievements tubes).
We reviewed the main inputs stages now using a symmetrical assembly. More generally, we have increased our specifications to improve, refine tolerance components used. We also optimized the operation of preamp tubes with the addition of damping rings to the total removal of all micro phonics effects.
Finally, the quality of transformers used both for power supply and for output stages have been a more careful quality of manufacture.
