Watts! How many do we need?


Got a new amp. Accuphase P-4600. It’s great. I love it. 
150 watts into 8 ohms, 300 watts into 4 ohms and it has meters so I can see wattage. Have them set on freeze so I can see the highest wattage during the session.

My Harbeth speakers are not very efficient. Around 86db. Their impedance is an even 6 ohms dipping no lower than 5.8 ohms. 

Playing HiRes dynamic classical recordings  ( Tchaikovsky , Mahler) at room filling volumes I have yet to exceed 1watt.. 

Amps today offer a lot of watts some going to 600 even 1200 watts. Even if you have inefficient speakers with an impedance that dips down to 2 ohms do we need all this wattage or should we be focusing on current instead?

I have a bunch, and I’m thinking I use almost all of them. 1000 each in my Legacy IV 2 Amplifier. It runs the Legacy Focus SE’s Mains. 600 each in my 5 channel Legacy IV 5. It runs my Side Phantom’s and Rear Deco's plus the Center Marquis. All are Legacy. Not sure about the 4 subs I have. They are Legacy Foundations and have 1000 each. I invite folks over and we play video Concerts. I try to keep the system humming at 113-115 DB with my Tripplet meter. It’s better than a true live concert. The punch is unbelievable. Favorite is the Eagle’s Farewell tour. Just killer. We are 10 feet back from the soundstage. 65-inch Sony Q-Led does the video. System never heats up, and we always play the entire two-hour concerts. Can lay your hand on the Amps and they are barely warm. Sometimes we pause as I get questions about the system and its impossible to talk. But I USE my system.

Anyone that listen at 113-115db are either def or stupid, or if doing it routinely maybe both?

If you are not def, is it then something you aspirer to be ?

Why would a music lover try to intentionally destroy one’s hearing?

As older we get our hearing for most people deteriorate and unfortunately for many it hinders their ability to function 100% in social gatherings and for some people they choose to redraw a bit from social life.

Also as it is now, there is nothing you can do if getting tinnitus which even is a much bigger problem.

i worry about the younger generation that blast music into their ear canal’s with in-ear headphones, I am guessing that most of them will have big hearing/tinnitus problems before they are 50!

Don’t get out much, do ya? Lots of folk go to a monthly concert. And they are played in the 113-115 range. Many times, much more than that. You think all those thousands of listeners at the live performances are going deaf? It better hurry up if it’s going to affect me. I’m almost 70 and have been around loud race cars my entire life.... (And a dash of music). You sound boring! But enjoy life however you want it, I know I have enjoyed the heck out of mine.

Boring? Not in the least, but who am I to tell a seasoned race car junkie with a splash of music exposure to boot.

Yea, I’m serious. Here is my in car camera view of one of the thousands of passes I’ve made in the last 25 years of driving one of these things. Loud? Most certainly. But I like music loud also, when its called for.
