I don't know.. i mean the only thing that i am not happy about is the broken gain. All the other things don't bother me much.
ARGH.
Waiting for sellers response pics:
just for clarification, the mtx 2300(w) was available in black or white and was made in 1995(the ones with the fins, the pic of my amp) and the 2300x(w) was available in black or white and came out in 1998. Both versions are rated at 150x2 at 4 ohms, 300x2 at 2 ohms and 600x1 at 4 ohm mono and were very underrated.The x is listed as the one i posted on the http://www.mtxaudio.com website, they don't list the one with the red lettering as far as I can see.
I thought the 2300x was rated 200x2... but i may be wrong, it probably is 150x2 mine no longer has the sticker on the back.
