There are two groups of audiophiles I believe on this subject. # 1. is the high efficient spkr. low watt amp guys.#2 are the low efficient spkr. high power guys. They both have good reasons why one is better than the other. I personally like somewhere in between,20-70 watt tube amp and 89-93 db spkr.The more efficient a speaker is,the louder it will play per watt, some believe the high efficient is thin and bright. Some believe the low efficient needs gobs of power to get them to sound good. You will have to come to your conclusion on this. Kind of like tubes vs solid state.
low efficiency speaker vs. high efficiency speaker?
What are the advantages and disadvantages of high efficiency speaker vs. low efficiency speaker? Does it mean that 93db efficient speaker will sound better than 86db?
