Probably get some dislikes for mentioning anything mainstream but I really like RF's Power series amps in recent years. They are rock solid and over rated. So is MTX's high end amps like the Elite series. I still have my Elite amp, thing is a beast and 10% under rated. They replaced the Elites with something else, no clue on em but their fugly.
For subs...I have never found a sub that literally impressed me over any other since the early 90's to be honest. Their subs, with the right application most any can sound pretty good. Some just handle rated or higher than rated better than others and some do better in smaller enclosures than others or have better SQ. I think the basics of speaker technology has pretty much been down pat for a very long time. With the right setup, any sub can pound, even Pyle. Seems most every brand, someonehas won a sound off or two somewhere.
edit: I meant under rated.
