I miss my Loudness Button and Tone Controls....

The SAE Parametric Equalizer in the early seventies was considered to be a very high end piece of audio gear. I used it for a while until I figured out that if a loudspeaker can’t do a particular frequency to your satisfaction, you can’t force it to sound better. You can emphasize it, but you can’t correct it (if that makes any sense)?.

Very interesting post... Thanks especially this part:

You can emphasize it, but you can’t correct it (if that makes any sense)?.

In the case of "mechanical equalization" of a room it is like in "electronical equalization" also, we cannot CORRECT a defect in the speakers/gear interaction or in the speakers alone, but we can put the emphaze on some frequencies range that will compensate without correcting the specs and defects or limits of the  gear itself...

You’d be amazed on how well a good a higher end receiver can sound once “professionally “ calibrated using its built in eq (parametric in my case.) Those built in auto eq systems don’t hold a candle to a manual professional calibration. When done properly, the results, ime, have always been better vs bypassing the tone controls or equalizer. Of course, bypassing tone controls is the way to go IF your room acoustics are near perfect, but that’s rare in most cases.

A high end receiver can never give the sound as a good two channel amp.

Do receivers really count as high end audio?

Do receivers really count as high end audio?

Certainly not less "high end" that an alleged high end amplifier in a non treated and uncontrolled room for me...

Acoustic trump any design of a singular piece of gear in S.Q. improvement /price tag RATIO...

High quality sound means more than just a high-end quality design of an amplifier .... No ?

They are not EQUAL expression and equal realities, save perhaps modulo acoustic methods...

To sound good something MUST be well embedded in his working dimensions: mechanical,electrical, and especially acoustical...

Then owning a very good receiver does not means a low sound quality  "de facto"...

But a good receiver comparable to a good amplifier are not so much numerous indeed...

The very good Kenwood receiver i one times own was inferior to my Sansui amplifier on all counts...

But i never compared them in a well controlled environment for sure... It is my deduction...
