What Matters and What is Nonsense

I’ve been an audiophile for approximately 50 years. In my college days, I used to hang around the factory of a very well regarded speaker manufacturer where I learned a lot from the owners. When I started with audio it was a technical hobby. You were expected to know something about electronics and acoustics. Listening was important, but understanding why something sounded good or not so good was just as important. No one in 1968 would have known what you were talking about if you said you had tweaked your system and it sounded so much better. But if you talked about constant power output with frequency, or pleasing second-order harmonic distortion versus jarring odd-order harmonics in amplification, you were part of the tribe.

Starting in the 1980s, a lot of pseudo scientific nonsense started appearing. Power cords were important. One meter interconnects made a big difference. Using a green magic marker on the edge of a CD was amazing. Putting isolation dampers under a CD transport lifted the veil on the music. Ugh. This stuff still make my eyes roll, even after all these years.

So I have decided to impart years and years of hard won knowledge to today’s hobbists who might be interested in reality. This is my list of the steps in the audio reproduction chain, and the relative importance of each step. My ranking of relative importance includes a big dose of cost/benefit ratio. At this point in the evolution of audio, I am assuming digital recording and reproduction.

Item / Importance to the sound on a scale of 1-10 / Cost benefit ratio

  • The room the recording was made in / 8 / Nothing you can do about it
  • The microphones and setup used in the recording / 8 / nothing you can do about it.
  • The equalization and mixing of the recording / 10 / Nothing you can do about it
  • The technology used for the recording (analog, digital, sample rate, etc.) / 5 / nothing you can do about it.
  • The format of the consumer recording (vinyl, CD, DSD, etc.) 44.1 - 16 really is good enough / 3 / moderate CB ratio
  • The playback device i.e. cartridge or DAC / 5 / can be a horribe CB ratio - do this almost last
  • The electronics - preamp and amp / 4 / the amount of money wasted on $5,000 preamps and amps is amazing.
  • Low leve interconnects / 2 / save your money, folks
  • Speaker cables / 3 / another place to save your money
  • Speakers / 10 / very very high cost to benefit ratio. Spend your money here.
  • Listening room / 9 / an excellent place to put your money. DSPs have revolutionized audio reproduction
In summary, buy the best speakers you can afford, and invest in something like Dirac Live or learn how to use REW and buy a MiniDSP HD to implement the filters. Almost everything else is a gross waste of money.
I love this. I know it’s been beat to death but I do love the balls of it. Let’s face it. The recording is where it all starts. If it’s crap you can’t make a silk purse out of a sows ear. If it’s a fabulous recording- the studio/hall, the microphones, the mixing board, the tape or digital, the final production....now we have something. From there it’s your speakers and the room they play in. You can converse about cables and such but the yield is much lower. Make your room right, your choice of speakers right and enjoy the music. The rest is fiddling. Nomex suit on. Tuning out. 
+1 I agree 100% with OP.

S P E A K E R S are F A R more I M P O R T A N T than nonsense from tweakers ! ! !
