Newer Class D and Icepower specifically meet the criteria, are becoming increasingly popular and are more practical for most, and may be undercutting the value of the traditional heavy, power consuming and expensive to build well monster amp, which was always a niche item to start with.
I know in my case I needed the high current, high power amp to drive my larger speakers properly and to the max. I considered Class D or traditional monster amp. I decided to go Class D and have no regrets. Every time I listen, the sound just blows me away.
In general, greater efficiency is the wave of the future. That can mean a more efficient amp to deliver the power and current needed as in Class D or more efficient speakers that require less power and perhaps also current. Either approach or even both in conjunction to some extent can greatly help bring an otherwise under performing system up to par
