US Amp Mods?

[Oak244 0]

Has anyone ever had or heard a modded US Amp? I am speaking to a guy who says he upgrades US Amps and when I asked he said he makes them sound clearer. Any idea what he means?

Crazy I know lol I may try it sometime just to see if I can hear a difference. I would propbably do it to the 400x since it costs the least to replace lol and plays the all important midrange. He did say he could not do anything to make a change on the USA-50 running my tweets, but the other 3 he said he would mod if they were his amps.
