Years ago I got the Audioquest Niagara 1000. Even without breaking in, immediately love its relaxed, sweet, juicy, smooth and liquid clear sound quality. When the new Niagara 1200 comes up, I was attracted but found no need to get another power filter. After reading reviews all over, I decided to get one (reviews truly are persuasive!). The Niagara 1200 cost a bit more, but looks way humbler than the 1000. Unlike 1000, the 1200 needs over five days of break-in. It was a bit dry, cold, forward and sharp at first. After running in issues improved to a degree. The 1000’s still has more easy going, friendly, warmer sound. One obvious advantage of the 1200 is lower noise floor, more vivid detail imaging etc. This is not to say that the old Niagara 1000 sounding ‘dirty”. I found best cable to connect the Niagara 1200 from wall is important to use AQ’s own. If you want the 1200 to support both amplifier and pre-amp, CD or DAC front end equipment, my recommendation is Audioquest’s Thunder. I would not recommend the one that’s a level above Thunder. I love the Thunder’s fuller bass foundation, dense mid body image, even though it’s the lowest model in class. As from Niagara 1200 to your equipment, it works well with other cable brands to your choice. As I am not writing a “full review” here, let me conclude it this way. If you have an aggressive system that tend to sound bright, hard and thin, the 1000 will do a better job. Otherwise, the Niagara 1200 should be a better choice. Both 1000 and 1200 are nonetheless great gadgets anyway.
