"ART DPS II didn't impress me"

Feature:
Gets a 6 because besides gain and output you don't have any other control on your sound. There are a couple of factory presets and that's it. You can't really tweak the sound to your liking.

Quality:
It's very well-made. If you decide to buy one, it'll last for a very long time. The preset selector is cheap and points somewhere in between presets. Say if "Piano" is at 2 o'clock it points somewhere between 2 and three.

Value:
For the value it's not bad. It's really hard to find a two-channel pre-amp for about $200. But then again you don't get the quality you would want. Hate to say it, but my PreSonus TUBEPre works way better, and it's $100, making two of them still cheaper than the DPS II.

Desirability:
The looks are deceiving. It's a poison ivy! If you have money to blow the DPS II will add a sexy module to your rack setup. But I'd rather get something that works good. I returned my DPS II.

Sound:
The sound is alright. Not as good as I expected though. Tends to amplify highs a little too much. If you have the slightest noise in your circuit it'll be amplified unbearable. Would work fine as a quick and dirty sound exciter for live shows. NOT recommended for studio use at all.

Support:
If you're a pro the manual's useless for you. If you're a novice the manual is useless too. It's the least informative manual I've ever seen. It's not written for beginners, nor is it written for pros. They've included some information which is useless in any case. I also tried to contact ART before I got the DPS II (which i returned) and never got any replies.

Overall:
I don't recommend this thing to people who can afford higher-end pres. In the end you get what you pay for. So if you can afford a PreSonus MP20 go with it and don't even think about the DPS II. Because of the noise, the only people who can use it are people with high end noiseless instruments, on an all-Monster setup. Then again folks with that gear can afford better one. Bottom line: if you buy it, make sure you can easily return it... just in case.
