Wish I had my old equip
Hi, I guess we'll stick to digital formats!
No,No,No! Audio note 300b single ended pure class A amp, black box moving coil stylus on any decent turntable (Cast iron platter) preferably English and that goes for the speakers too.
Just have to let it warm up a bit and don't have the amp or turntable on any surface prone to sympathetic vibrations.
But to the point I believe WAV's are the best but most people including myself are perfectly happy with any MP3 file at a reasonable Kb's rate.
But and a big but, many software programs for some reason just extract the data and do nothing else to the file. CD/DVD players have complicated software to equalise the sound built in, you don't know it's doing and what it's doing is making it sound better.
If you like to store your music collection to a digital media then fine but download a free program called Mp3Gain and it will correct the amplitude of your music, just research the program please if in doubt it just sounds far less distorted and all you need to do is adjust the volume a little higher.
Many burning programs will 'normalise' the tracks before burning, the same thing really and if making yourself a CD for the car you don't want to be adjusting the volume all the time so normalise the files beforehand.
As stated above you can't always get the track you want at a good bit rate or a WAV file, I once DL'd some music for someone and one of the tracks when normalised had a gain of 136 Db!
If I had not checked it would even on a measly 4.8 K rig probably would have left the guests wearing speaker cones.
Low end PA speaker sensitivity, how much sound it kicks out per watt.
100 Db output measured with a 1Kh sine wave at 1 Watt input with the microphone 1 meter away in an anechoic room.
So to get 101 Db I put in 2 Watts, to get 102 Db I put in 4 Watts, to get 103 Db I put in 8 Watts, to get 104 Db I put in 16 Watts, to get 105 Db I put in 32 Watts, to get 106 Db I put in 64 Watts, to get 107 Db I put in 128 Watts, to get 108 Db I put in 256 Watts, to get 109 Db I put in 512 Watts and to get to 110 Db I put in 1024 Watts! It's a Logarithmic scale you see and as you can see very easy to run out of power and thats why your headphones work so well I suppose.
Regards.
