pmdiaz23 ..... no offense, but as owner of a 286a I would have to describe the sound of that pre as such ...... imagine a completely transparent sounding pre and hook a mic to it.... then take a sock and put it over the mic and it will sound roughly like it would if you ran it through
a 286a.
If you're looking for "crystal clear" then I would strongly recommend
NOT getting a 286a.
I do still use mine
if I have to or sometimes as a pre for kick drum bc you can use the hi/low freq enhancer section as a pseudo EQ..... but honestly my Audio Buddy pre-amp is at least twice as clean and versitile as the 286a. Very colored (veiled) in a not-so-good way.
Granted they are inexpensive but so are a lot of other much better sounding and more versitile preamps. DMP3 VTB-1.
I have used the ART Pro Channel some and I found it to be very nice sounding (colored but not heavily) ... "warm" but clear and detailed... and has shitloads of gain. I used it on guitars, vocals, and keyboards (cranked and smashed .... fun sound) and it sounded great ....not transparent for sure but colored in a good sounding way.
I'm not entirely sure, but I believe the ART MPA is a completely different preamp design (someone correct me if I'm wrong) and have not used it so I cant say how it sounds.
I also own the ART VLA compressor and it is a great compressor used by quite a few of us here on this forum. Saying ART stuff sucks as a blanket statement is simply not true in my opinion.
I have not had a chance to use the RNP either but based on all of the the praise given on various forums .... sounds like a great bang-for-buck pre.
As for Focusrite.... I agree with Giganova. I had the Penta for a while and sterile is exactly the word I would use to desribe it .... apparently all of the Platinum series use the same preamp circut. It did have a nice faux tube saturation knob which I thought sounded really good although not actually tube-like. I guess you could say its very clean sounding but it just kinda seemed to make everything sound smaller and wimpier.
From what I've read the Grace preamps are know for their transparency and completely un-colored sound.
