Anyone tried JPlay?

Did I report elsewhere (can't remember) that with Dariusz's interconnect cables I was able to hear this for the first time, despite the fact I would have sworn BLIND that you were all imagining it before. :)

Obviously you don't want to get too hung up on these sorts of tests because they never tell the full story, but it certainly gives a very good indication as to the resolving power of what's upstream.[/quote]

Great to see that somebody else actually believes there are 3 notes there. Only Southsiders can hear it.It must be the air on this side of the city.

BTW, Tony, I think I figured out what the reason for being able to hear those 3 bass notes 47secs into that Shelby track on your system & apparently on nobody else's system. It seems to be got to do with room acoustics & intelligibility. It would appear that your room reverberations at that frequency are under control. There's a nice test for this - See here for more details http://www.whatsbestforum.com/showthrea ... ility-Test

Simon,
Can you confirm which bass note is ACTUALLY split into 3 - I can't remember which of these two it is - is it th ebass note just before she starts singing or the one before that?
I have a link here https://docs.google.com/open?id=0BzRUtX ... mVzRE1yUnM where you can download an excerpt of the 3 seconds before Shelby starts singing.
I would appreciate if you can confirm which one it is as I wanted to get someone to test it.
I don't have a room/system that resolves it or I would identify it myself - it was only in Tony's that I spotted it.

It's on the up-beat to the bar where she starts singing, so not the very final note before her voice enters, the one just before that.

I think.

Thanks Simon,
Now I can drive some other people mad with it & turn them off this Shelby Lynn track forever :)

Fantastic! "Everything I ever wanted to know, but was afraid to ask about that track!".............

definitely don't want to hear that track again for a while!!

Tony, if those bass notes are the ones I listened for when I was over with you, I found it almost impossiblel to hear . However there was a rim shot that was obviously better. Does this still hold.

I suspect that moving the speakers or changing the room around may well upset this - it is called room intelligibility. I don't know if the speaker position or furniture in the room had changed? You know the way some rooms are so reverberant that even speech is difficult to understand? Well this is a measure of intelligibility at the frequency range of normal speech. This sort of intelligibility analysis is done for recording studios & concert halls. Concert halls can be categorised into being most suitable to different music formats, chamber, orchestra, rock, etc - I read a paper about it somewhere, I'll try to find it if anyone is interested.

Anyway, our rooms can also be analysed for intelligibility using a MATT test - see here http://www.asc-hifi.com/matt-test.htm. According to the site "The objective of performing the MATT test in your listening room is to determine where you might move your speakers, listening position, and/or where to add acoustic treatment to your room to obtain the highest quality sound possible from the components in your listening environment. This is done by recording the playback of a carefully selected set of tones designed to evaluate the way in which a loudspeaker system operates relative to its surroundings."

When I read about room intelligibility, I remembered this 3 note bass in Tony's room & thought that it might well be this that is at the root of what we heard.
The interesting point for me is that all we did in Tony's was change from the Cyrus CD8 CD player playing the dreaded track to my DAC playing the same track, nothing else changed. Yet we heard what sounded like a single bass note being rendered as a 3 part sound. This means that the MATT test may be extended from just a room intelligibility test to a intelligibility test of the playback electronics.

To do this would require eliminating the speakers & room i.e use headphones, I guess - with good quality headphone amplifier & good headphones, it might be easier to control the variables?

The other thing that interests me is that this album has now been released on SACD - I wonder has anybody bought it? How is this part of the track rendered?

Hi Mick Not sure what you mean by rim shot. I have found it hard/impossible to pick out that single note since. At the time speakers were just about run in. The room was arranged differently and one sat very close to the speakers. Maybe this somehow allowed us to hear or created the conditions that suggested the note was 3. I don't know. Will try Johns suggested matt test some day but will try out the track after a stiff drink on my headphone amp.

John, have you tried the Linux drivers mentioned earlier?

Not yet - haven't had the time. But I have had emails from a number of people & they seem to work fine! They are also listed on the M2tech site so seem to have "official" approval :)
