yah they'll have the same prices sometimes, and sometimes different, thats how business is, lol someone gotta be better at some point.
So in terms of the Alping MRP500 amp.
Honestly, yeah it's pretty good,but I wouldn't recomend it, it's quality isn't the greatest. for $299 you can get such a better amp, even if you didn't mind spending a little more on a JBL that would be perfect. Plus, in audio terms, it's Signal to Noise Ratio is very very ****ty, you won't get clean bass from it
I'm going to PM you with an offer of something

And see if you like it !
PMing you now
