Meier Audio Corda Monoblock

Dunno whether this'll interest anyone here, but I thought I'd post it anyway...

This little beast is a 40 watt monoblock power amplifier, from Meier Audio, the company that usually produces headphone amplifiers.

They cost about £1,000 per pair, so they are not cheap, but claim to offer performance heard only in amplifiers costing several times their cost, despite the relatively modest 40 watt rating into 8 ohms...

Is that meant to be 175W @ 1 Ohm?

How are their headphone amps regarded?

"but claim to offer performance heard only in amplifiers costing several times their cost"

Heard that before

 

Perhaps its not designed to go down to 1 ohm?

Their headphone amps are pretty highly regarded. With that being said, I was not really too keen on the HA-1 for the money it cost when compared to the X-Can which for me is more musically enjoyable. But I havent heard the higher ones.
