Auralic Merak Monoblocks (200W/400W)

These were purchased from Addicted to Audio (Australia's authorised seller) about 5 months ago. 

They work flawlessly and produce a really incredible sound, which I would describe as powerful, precise, elegant and neutral, but far from col or clinical.

 

Each Monoblock is rated at 200W in 8ohm and 400W in 4ohm (continuous power). Both are fully balanced. They incorporate an innovative hybrid design (half way between class A and D, at least this is my understanding), in which the advantages of class D amplifiers (small size, efficiency, zero heating) are paired with those of class A/B amps (high energy storage, massive power supply, and great control on all speaker types, including difficult loads). Each monoblock has a linear power supply and 56,000uF capacitors array and can store up to 120J of energy, while remaining 90% efficient. This means they run stone cold even with low impedance speakers at high volumes

They have a circuit (which can be bypassed) that switches the amp on or off when a very low input signal is detected (or not detected), while keeping the output stage on at all times. This results in the amps being always ready to sound at their best (no need for any warm up time), while consuming virtually no energy when at idle.

These have only balanced line in, and each of them has a low level line out that can be used to send the signal to active subs or more amplifiers.

The exceptional quality of these mono blocks is confirmed in several reviews. Here are some examples:

I purchased them to drive my Magnepans 1.7, a notoriously very demanding speaker, which they did beautifully. I have now sold the Magnepans and do not require these anymore, plus I am moving to a larger house and I need to cover some extra expenses.

The original boxes are missing but given the small size, contained weight and simple shape these can be packed up professionally and safely posted anywhere.

This is the 230V version, but should be fairly easy to convert to 110V.

Buyers pay shipping and PayPal fee (3%). I can ship with your preferred courier.
