ML1501 - “Maedeup” NIGC Mono-block Amplifier (Revision 3.3)
The Maedeup is our premium reference amplifier.
-
Make no mistake: This amplifier is for audiophiles who want it all - without compromises.
The Maedeup is a real ‘green’ alternative to the many expensive, high-energy consumption, single-ended tube devices on offer.

-
The design brief was clear: The Maedeup should offer the absolute transparency, detail and sound stage capability of the Bosangwhas. However, in addition, it should also introduce into the presentation some sought-after characteristics of single-ended triode designs such as warmth and body.
-
Like the Bosangwhas, the Maedeup is based on the classic National Semiconductor LM3875 power op amp from the Overture audio series. At Musical Laboratory* this op amp is the key signature of our sound. We love the (relative) simplicity of this chip and because its internal architecture has been designed to support extreme sound quality - mostly Class A operation, individually current-sourced stages - not to mention the incredibly short signal paths which can be achieved with such devices.

-
In fact the Bosangwha internals were used as the basis for the Maedeup. What follows next is a process of voicing each passive in the circuitry until an optimum combination - based on the the original design brief - is achieved. At Musical Laboratory* we tried a large number of passive combinations - from the mundane, to the vintage, to the exotic, to the very-hard-to-find - to bring to you the musical performance you deserve.
-
Finally, we dressed the results up in two of the most gorgeous enclosures we could lay our hands on, which can be colour matched with Paeonia. The Maedeups can be ordered in :
- Gloss black with zen purple highlights and purple macrame knots (see picture above)
- Gloss black with red highlights and red macrame knots (perfectly matches Paeonia)
- Classic gloss black with black macrame knots (available soon)
