Great amp,especially for the price
I bought this ClassD Audio SDS440CS amp in Feb of 2013 as a replacement for my class A/B Aragon 4004, which had a channel go out. I needed a high powered amp that was capable of driving my lower efficiency (86db/1 watt) and low impedance (4 ohm) Magnepan 2.7QR speakers for both 2-channel music listening and home theater usage. After 5 months of ownership, I can say unequivically that this is a great amp for both purposes. Initially, I was concerned whether the 440, at 1/3rd the size, weight and price of the Aragon could properly drive my notoriously power hungry speakers. But this amp powers the Magnepans better than my older Aragon ever could. It's very powerful(440 watts@4ohms) and very dynamic while also maintainiing a very low noise floor.
This amp is neutral while being very detailed from top to bottom. This neutral quality is critical in tailoring your system to your preferences. If you want an accurate and neutral system, just pair the amp with a neutral and accurate preamp and speakers. If you prefer a warmer system, just pair it with a warmer preamp. I'm using a tube preamp with NOS (new oldstock) Mullard tubes and have acheived the sound I like; a touch to the warmer side of neutral. This amp passes along the slightly warm character of my VTL preamp without hindrance. If I wanted a more neutral system, I would use a solid-state preamp or a more neutral tube preamp such as an Audio Research.
Perhaps the most unusual quality of this amp is how 'green' it is. It consumes so little electricity to,run that I just keep mine turned on 24/7. Even after hours of high volume use, it only becomes slightly warm to the touch. I highly recommend the SDS440CS amp without reservation.
