Nelson Pass makes a great sounding pure class A amplifier series with the prefix of "XA" that sounds exactly like the best tube amplifiers, but are actually solid state. They sound like tube amplifiers due to the class A configuration. Warning... they run hot as hell, because of the high bias, and your electric bill will burn a hole in your pocket as well. Their cost to watt ratio is very high with a 30 watt stereo amp costing over $5,000 and a pair of 60 watt mono blocks run about $11,000. The pair of 100 watt amps are out of sight for most of us, but go for it if you have the money. The wattage of this series can go higher than 100 watts. You can check these out if you are rich. In conclusion the XA series would be great for efficient speakers like horns, and for the rich with inefficient speakers.
