Just got AQ Niagara 1200 ...

I just replaced my Richard Gray's 400 Pro with the Niagara 1200. Stunned by the difference it made. I had the NRG-Z3 but switched to a Nordost Red Dawn. The Red Dawn is different from the NRG (to me) but not in a good or bad way really. One song sounded brighter but the other two sounded clearer. The Niagara is still breaking in so this may be a moot point for now but these tweaks do make a difference for sure.

If it were me I'd stick with the Niagara.I used to have PS Audio and it created noise issues rather than helping.

I will be downsizing my system and selling my Niagara 1000 soon, but not on this website.

Just moved from NRG-Z3 to Thunder off 1200. Listening, smiling and shaking my head! Now i'm on quality conductivity bandwagon! ... looking at Uptone Audio EtherRegen and USBRegen little boxes :) 

I started out with the Audioquest 1000. I liked it so much I sold my PS audio P10.
I eventually moved the 1000 to my home theater equipment and bought a Niagara 7000 for my Audio system.
