I'm a confirmed basshead (1000 Watt amp and 2 JL Audio 10W7 in my car)
If you put the right power on the the mad dogs they'll play everything you want and with plenty of punch. My FiioE12 is cheap but delivers that sound very well. I would imagine that some of the other powerful portables or desktop amps will do the same for the Mad Dogs
You are definitely a basshead! I only have a single 10" JBL in my truck driven by 600 watts and that is plenty! I'm also 52..............
Caveat to your last statement - they did not do it for me - only wish I had them when I had all this vintage amps around. It may have made the difference.
