The Perfect Room

[Jud]

I like to write long comments, but let me see how brief I can be here:

- If your sound is screwed up at a prior point, there is almost nothing you can do at any future point to save it.  ("Almost" because digital grants some slight exceptions to the rule, as in async USB helping to lower incoming jitter by setting the data to a new clock.)  This includes the room.

- The brain is a wonderful thing and is capable of subtracting room effects to let you know when your system is producing good sound.

- If your room is so bad that it makes truly great sound coming from your system lose its magic, then what are you doing living there?  (I'm actually more than half serious here - it was certainly a big consideration for me when my wife and I were going over the plans for our house.)

Some interesting comments here about the importance of the room.

My room(s) have a particular problem. Essentially they are three rooms in one. So my speakers share the bass between 3 rooms (simplistically speaking) but the treble is beamed down to the listening position without significant attenuation) anyway whatever the reason there is (or was) a big suck out in the upper bass region in my room resulting in a thin technical sound. I have heard transmission line speakers in my room reduced to tears (ok their owners) because they sound so anemic in the bass and upper bass region. Not at all to be expected of Tx line speakers. And then back in their own room sounding wonderful. As stated elsewhere I was extremely lucky to have speakers that (uniquely?) allowed me to tweak the positioning to boost the bass and upper bass output. I don't see how changes in the electronics could have reduced those effects significantly without tone controls (uurrgh).

BUT on the other hand there are substantial room effects here that were reduced big time by my XX NOS front end - I used to get a big standing wave down the length of my room with my old system but with NOS1 that has completely disappeared the sound is very even now walking down the length of the room and from side to side (even with W8).  So it is not straightforward.

I think Peter is absolutely correct when he says that if you want to hear how your system sounds go and listen outside the room. Things are not so clear when you get inside the room for sure.

I do agree with Bert that - the changes due to the front end (i.e. W8 vs W7) audible in any room because they are usually about resolution.

Wouldn't it be great if hifi was easy?

Standing waves are frequency related!

Hey Christoffe nice one - I would like a Rubens tube to replace our gas fire! I am sure I could rig something up.

This is a good idea for romantic hours with appropriate music via the NOS 1.
I will replace my open fire immediatly.

Less standing waves in your room with the same tune is a result of a frequency shift with the NOS1 to the positive of SQ.

Nice links Joachim. Everybody should dive into them. But :

Less standing waves in your room with the same tune is a result of a frequency shift with the NOS1

This doesn't make much sense to me ...

Paul had his reference system prior to the NOS1 with standing waves.
Listening with the NOS1 the SQ changed for the better without the standing waves.
Something happened. We can't alter physics and the only explanation is a frequency shift for the better unintended.
We know that a replacement of one component in our chain changes the SQ. (Mani with his Sauermann's and yours with the future speakers)

What super strange conclusions you can have.
Besides : So, when there would be a "frequency shift", don't you think the standing wave(s) will exhibit elsewhere ? I sure do.

Peter

In general my wife agrees with you. He, He

I wrote listening to "the same tune" ............... .

Standing waves doesn't alter in our room with the frequency.
What is your explanation that with the NOS1 the standing waves are gone in P's room? Placebo?

I didn't watch that YouTube. But with XXHighEnd standing waves diminish by far already.

Maybe when I have time I may spend a post about it, *again*. That's why I have no time for it now. Haha !

You should, because it shows the relation of the distance from the speakers plane to the wall and the appertaining frequencies.

The name of the company/site is Phasure ("phase sure") and many of us use "phase alignment" in XXHE.  That should give a hint what may be happening to the sound waves such that standing waves are minimized or eliminated.
