Where to go (if anywhere) from NAC52?

If I sell the CDX/XPS then the money could go towards upgrading the 500.  The 500 serial number says it was built in 2000.  AIUI with the DR upgrade so much is replaced that a combined service isn't necessary - not sure whether that is true or not.

Upgrade & service is priced differently (higher) than just upgrade.  But is cheaper than service and upgrade done separately.

It's also worth considering a PS on the NDX.

I've always assumed it to be a thrown milk bottle (remember those)  & it lands 'half left' & 'back' in the soundstage,  & with the distance effects added its sounds something like >50m distant.

Yes - I've always envisioned it as a bottle of some sort.

Re the breaking glass agin:  BBC R-2 (Ken Bruce) just played Private Investigations so I perked up my ears & got set for a listen.  I was on iRadio & the BBC HLS 48kHz 339kb/s service.    Using the SPL meter on the iPad I had the volume set for around 70-75dB (keeping in mind it's a subdued & moody & not a loud recording)  the listening position was aprx 2.5m from the speakers.    The breaking glass was as I usually hear it, distant but very distinct & the SPL was around the 50dB area.    I Then fired the recording up from the NAS & with the volume at the same level & there was no obvious difference.

Just out of curiosity, I played it in the car a few days ago. Surprisingly, I could hear the breaking glass quite clearly despite the engine noise.

Did you hear the fragments of glass hitting the floor a fraction of a second later?

Yes of course,  I hear it as a live recording of a real bottle hitting a hard surface such as concrete or tarmac & the fragments of glass spreading out on the surface after the initial impact.     The cat on the other hand is a manufactured sound effect.

Perhaps you're only hearing the bottle-neck?  

I have always heard it as an (outside) light bulb breaking in a (now) dark alley with a cat (garbage-can-hunting interrupted ) and perhaps the cocking of a weapon via a private investigator not wishing detection.  But then numerous people on this forum who have never met me or heard my (very modest) system have implied (told me) I can't hear.  So take my mention with appropriate grains of salt.  And the knowledge I take a lot of drugs.  Plus my self-knowledge ranking is a mere # 42.  Ho-hum.  Back to the music.

I like this scenario of a bulb breaking or being smashed and then the fragments hitting the ground. The glass sounds more delicate than a milk bottle.

Phil

Defo a bottle of some sort;  I hear the impact that sounds like something much more substantial than a lamp bulb,  also the scattering of fragments is too soon after the initial impact (assuming if it was a lamp it would be 2 or 3 metres from the ground)     To open it up some more,  how about the click a few seconds after the glass,  was it cocking a handgun, a click from a briefcase lock or a door lock??

Yeah yeah I know,  I need to get out more  

Well it could have been a milk bottle thrown at the cat by someone trying to sleep! I’m playing it from the Sultans of Swing.

How would a gun cocking fit into the story? Not as an alternative method of silencing the cat!

An object will fall about 2.4m or 8 feet in 0.7 seconds.

The quite loud sound about 4 seconds after the fragments hit the ground sounded more like a door closing in a echoing environment. Not trying to prolong this though! 

Phil

Agreed,  not prolonging.      However with my mad scientist hat on,  the few gram fragments of a broken light bulb will take a lot longer than 0.7 secs to fall 2.4m.       Its a thrown bottle for sure.  

I just suggested the gun cocking was a bit of a tease (my buddy in USA is convinced)   For me, if the 'song' does contain a story, it's a private detective, seedy lifestyle, living on nicotine & whiskey.    I hear the click as a door latch.

The classical vertical distance from rest travelled by an object in a vertical (g)ravitational field is 

1/2 g t**2

It velocity is

 gt

Both ignoring drag. 

g = 9.81 m/second/second.

.............  and to do so is where you've got it wrong.   A sliver of thin lamp glass will flutter to the ground,  not quite like a feather, but air resistance drag would be a big player.

Thin glass from a lightbulb may have enough surface area relative to mass for wind resistance to slow it measurably, but the sound is not that of a light bulb, but is consistent with a bottle, possibly milk bottle. Aside from the frequency being different, a lightbulb has a characteristic sort of pop sound at first as it implodes due to the reduced internal pressure.

At the risk of prolonging this diversion, any thoughts on the tearing paper sound between the meow-like guitar wail and the glass?

My dogs didn’t bark. There is no cat. What glass?  I must need to upgrade my record player. I wonder what she’l say...

The tearing paper sound to me sounds like someone's foot dragging on the ground - like they had been walking, then sort of stopped with the foot meeting the ground and sliding a little.

The glass sounds very like a bottle - I had assumed a whiskey or beer bottle

I was merely quoting in a well defined circumstance (no drag).

The sound of the fragments tells the actual story - it is the sound of the heavier fragments followed by the lighter ones shortly afterwards. Low velocity drag on spherical objects is proportional to velocity while at high velocity the square of the velocity. You could always break a light bulb yourselves - I doubt if there is much time dispersion as glass is actually quite dense. 

Unless the Music was recorded in a real environment I doubt the glass was broken 50m away from the microphone. It was to create an illusion which Jeff tried to capture, and I merely liked.

For those that hear it loud and clear, if any have a spectral analyser can you measure what the glass break sound covers? That may help rule in or out HF frequency ear degradation, and point to whether is is mid or top that might be the issue.

Otherwise all previous thoughts/questions remain.

I'm rather enjoying this thread. Here's a jpg of the frequency spectogram, courtesy of the wonderful Audacity. Ripped from LP, definitely in left channel. For what it's worth, the "sshhh" noise to me sounds like a bottle being opened (fizzy drink/beer) and then the bottle being smashed.

But what brand of bottle was it?  I heard that it was a Stella Artois. Does anyone know?
