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'd agree with most of that, though the room the recording is made in can be corrected quite a bit through microphone placement and post-processing.  Still, you're right in that the ultimate limit is always going to be in the quality of the recording.  

I've been toying with the idea of trying out a Class AB or A/AB amp in my 2-channel setup, I realized that all I've owned has been class D (well, my computer integrated is a BASH amp).  But I'm leaning towards doing some physical room treatments first.  I have been using Dirac Live in that setup, and it made a big improvement, especially in the clarity and quality of the bass.

I use Amazon Basics interconnects, which are well built and inexpensive, and Sewell Silverback speaker cables, which are 12ga OFC and come pre-terminated with nice banana plugs, and are also inexpensive.

I’d disagree about electronics being more important than speakers.  I’ve demoed B&W 804 D3s powered by an Integra receiver running through a Magnolia switchboard and they still sounded excellent, and a clear step up from the CM10 S2s even with what would be considered a big electronics mismatch.  

Can electronics sound different?  Sure, and tubes in particular can introduce euphonic distortion that many find pleasing.  I’ve heard some tube amps that sounded great, and I may play around with one in one of my systems at home, but they’re not necessarily more accurate (which may or may not matter to the individual listener). 

Still, tubes aside, once you’ve found an amp that’s capable of handling your speakers’ load (which will be more demanding for difficult to drive speakers like Revel Salon2s, certain electrostats, or a notorious amp killer like the Apogee Fullrange), you’ve found enough power to drive your speakers to the desired dynamic peaks in your room, and the specs on the amp are good enough to not introduce audible crosstalk or noise, the differences between electronics should be pretty slim, other than DSP features which can have a dramatic effect on the sound.  

The distortion introduced by speakers and room effects will be orders of magnitude greater than that introduced by electronics.  Spend the money on the speakers and the room, and enough on electronics to drive them without limitations.
