Audioarts 4100 and tc electronic 1140

[Bmxrider799]

I am looking To buy a parametric pre amp and i was wondering if any one had any info on how the Audioarts 4100 or 4200 stacks up to the tc electronic 1140 or 2240 or the Furman pq3 or 4 because there is an audio arts 4200 I am able to purchase but can't find much info on it. I found one review comparing the Furman pq3 to the Audioarts 4100 but I was hoping to find some more information on how well the audio arts works to boost and amp into high gain
