Nearly all manufacturers do not advertise/exhibit their product measurements? Why?

holmz , It was stated correctly that this is a thread about measurements. Why not post some to discuss? It is a starting point, not a destination, OK?

Yeah - it could be interesting, but it is a lot easier to measure gear than an in room system.

 

If you look at my system profile I posted the in room measurements. If you read the system description you will see links to my components as well as some specs for my active speakers.

I only see the before/after measurements and the paradigm active reference mentioned. Are they doing the EQ themselves? Or is that happening elsewhere in the chain?

 

This isn’t a contest, this is a chance to compare ideas and obviously no one is perfect.

Your room measurement were nice to see the other day.

 

 @fleschler is starting a build I would love to be able to do, did you check it out?

Just now, but only a thick, door and another shot… so far 2 pictures.

 

He is building a room from the ground up and he posts measurements of the room, great stuff. BTW, your system doesn’t load properly when I check your profile. There are some "banging" systems I can’t even imagine in the virtual systems area. It provides inspiration for me personally, I don’t know about anyone else.

So yes, some not so much.

 

It took NO time to tell the difference once all fiver or six (I forgot) of his Pangea power cables were replaced with GroverHuffman cables.   Furthermore, my pre-amp was substituted for his Audio Research SP-28 and walloped it.  He decided to change the input tubes (6NG/6H6) as suggested from another audio engineer friend and that resulted in sound very similar to my pre-amp.   THERE IS NO NEED TO MEASURE OR BLIND TEST OBVIOUS SONIC DIFFERENCES THAT ARE SUPERIOR. 

Actually that is exactly what (and why it) should/could be tested.
I have never seen a fraction of an iota of measured difference presented in the cables, so it would be very interesting to know that they could be picked out consistently, and then why/how they are improved... Like “What is the mechanism that is at play here?”

 

You don't get this so stay off the Audiogon site.  My friend is so happy, he can hardly contain his joy and like me, listens at night for 2 hours or more.

We have two hypothesis:

1. It is psychological
2. it is real
   1. And maybe it cannot be measured.
   2. and maybe it can be.

I am interested in # 1 and 2B.

… ditto for anti vibration footers as well.

How to measure a room is a great topic for a new thread. All I would say is whatever software you use get a good calibrated mic. There is DSPeaker, miniDSP, TrueRTA, REW, and of course Audyysey, DIRAC and ARC.

If this is a rabbit hole you don’t want to dig you can have a calibrator do it remotely such as www.accucalav.com:

As for checking out virtual systems there is a text box beneath each one with a link "read more" which expands it. The links I mentioned are embedded in the description of my system.

As for the topic of "blind testing" it just isn’t necessary or practical. Look, I drop a component in the rack and let it break in for a few weeks. I take it out before the 30 day return period expires. If I can’t tell a difference send it back. If my face freezes in "grinrictus" I leave it in. The people who argue about blind testing are just using it as a crutch to win an argument. Look, you need a panel of "trained listeners", you need the proper setup to switch quickly, and lets not go there. If you insist the best you can do IMO is buy a ABX Comapartor from Van Alstine but without a panel of trained listeners it still amounts to a "Pepsi Challenge" to my ears.

 

@amir_asr ,

Funny how you regress to passive/aggressive mannerisms when you get called out.

Put the multimeter down and try listening with your ears. You might be amazed at what you discover.

Go ahead and tell me that my "boutique" audio setup sounds the same with a $30 power cable and a $500 power cable. Go ahead and tell me that again.

See, here's the rub. Once you know better, you know. And no one can convince you otherwise.

So quit trying to "save the world" from itself, and try listening to the music. 

Your channel is a joke, pandering to fools who are desperately trying to convince themselves that their $500 (insert piece of equipment here) is just as good as a $15K (insert piece of equipment here).

You ought to be ashamed of yourself, really.

 

BTW- If your room is difficult and you want a top shelf reference Earl Geddes is a fantastic resource, check this out. The title is home theater but the principles appy to two channel as well. If you use a sub check page 236 for setup tips. Earl's PhD thesis was on bass management in small rooms:
