Opinion: Turning Off the Filtering


Hi Everyone,

Just wanted to share with all of you some of my thoughts and one of the ways in which I most enjoy listening to music.

Have you ever spend a day in a noisy office, trying to talk to others? Or in a room with terrible acoustics, having a discussion? Have you felt yourself tired and exhausted after that? A lot of times our brain is working to filter out sounds in order to process words. To find the symbols which make up language in spite of the noise, reflections that we may find ourselves in.

This is what I most want to get rid of when I listen to music. It is why acoustics and speakers with dispersion control are so incredibly important to me. I want that utter ease, that ability to turn off all that processing and just listen. You may not have noticed this yet, so I'd like you to think about this, see if you can notice your brain shifting modes.

To me the best systems are the one's that are like being in the great outdoors. That feeling you get when your eyes can see for miles without interruption, but for my ears and brain instead of my eyes.

Is this you? Or did you not know this was you yet? :)


Best,


Erik

When I listen at lower volume everything is better including imaging.  A little bit more volume and sound becomes tiring.


To your last point, yeah, often I read exactly this and I want to suggest room acoustic fixes first, but nope, the poster runs off to buy new interconnects or starts shopping for amps << sigh >>

I think that our brain compensates for a great deal, and there is a lot of training we subject ourselves to which allows everyone to hear differently. This isn't just taste, but a matter of repeatedly growing neurons to process sounds in a particular pattern. They have done interesting experiments with training people to see upside down. The brain is doing a LOT of processing and wiring between our sense organs and our perception.

Going to shows and interacting with other audiophiles has really made me aware of this. So many people can go and sit in a poorly treated room and really get into the music. I cannot. I cannot wait to get home and clean out my ears.

The number of rooms I can listen to in any given show are a handful. One of the best sounding rooms to my ears is the Magico listening room. My home is nothing like that, but that is what I strive for.

Of course, headphones have a big advantage in that the room acoustics are removed from the equation and you are listening purely to the driver and distortion, so headphones are one way of hearing this effect, but you hear a lot more too.

Large surface speakers like ESL's and long ribbons, any speaker really that can control dispersion so that room effects are minimized are also ways in which this is improved, despite many ESL's having horrible frequency responses.

Best,

Before they discovered Transient Intermodulation Distortions (TIM) in 70s they made quite a few horrible SS amps. Internal overshoot of transitions was so bad that output transistors were going into momentary saturation causing tiny gaps in music. Again, brain was compensating but longer listening was very tiring.


This was before me, but very interesting. We take this all for granted. I don’t think it is even possible to buy a linear or switching amplifier this bad anymore. You would have to deliberately build one.

Dr. Leach’s paper in 1976 addressed this problem by naming a number of circuits that were important in the design, and that was the blueprint and standard for decades.

what do you have for a system currently ?
Hi Riley,

My speakers are all custom made. My living room is a pair of these:

That’s just half the equation though. Room acoustics are vital. That all comes from GIK Acoustics

Electronics are Mytek Brooklyn DAC, Parasound P7 pre, and ICEPower Class D amps.

IC’s are pure silver, balanced custom cables. Speaker wires are 12 guage stranded copper, nothing special.

Best,

thinking the system is very clean sounding, is bass a problem or no ? is it border line almost hot on the top end ? or do the speakers mellow it out ?
