Sera una Noche 45rpm EP of three selected tracks!!

This beautiful, Extended Play 45rpm 180m disc, presenting three of the best tracks from the first 96kHz recording of "Sera una Noche", was cut to lacquer by Len Horowitz on his legendary 1950 Scully cutting lathe with Westrex cutting head. Entitled simply, "Sera una Noche 45rpm" the disc contains (on side A) two versions of Gardel’s "Malena", the first with Pedro Aznar on vocals (7’ 38”), and the second, a haunting, original instrumental track of the same (5’ 06”). Side B presents the profoundly mesmerizing, "Nublado" (11’ 22”), arguably the killer track of the whole session, which was recorded in the little Gandara Monasterio church in the Argentine countryside, approximately two hours outside of the capital of Buenos Aires.



After Len’s “on the fly” lacquer cutting, the lacquers themselves were immediately sent to Quality Records Pressings for Plating, Metal finishing, stamper production and 200gm pressing.

Tape Hiss is about all you have gotten right on this one frank, time to upgrade, I dont hear what you are talking about on any of the tracks, there is the usual camcorder dynamic overload, expected from stumps, he didn't vet the recording and had the level up too high.
Looking at the waveform now - from about 4 mins in, quite distinctive characteristics there - I'll work out the right combination to look at and compare ...

To make it very easy: there are two percussion instruments struck repeatedly through the clip - I don't know what they would be, variations of a bell. One has a soprano tone, the other is like a contralto, much richer harmonics - the quality of these varies dramatically through that segment, starts off very clean, with good sparkle, then gets quite dirty and gluggy, almost turns into nondescript mush at times - I'm pretty sure the musicians weren't trying for this effect, ;) - so, something is going wayward ...
 
Camcorder Mic overload , yeah imagine that, from an internet you toob video ...... :djinn:

what about this one wooley and colored , system or internet recording .... ?

Point: You cant tell from internet video


The Magico system in the original video did show enuff to let me know it's serious , very serious , lot of dynamics macro and micro....

If the camcorder overloaded the characteristics would be very different from that - no, this is a system misbehaviour; there are plenty of YouTube videos showing the clarity of sound that should be there - say, recording live performance; you know, real instruments, etc, :) ...

The dynamics may be there at times in the system, but they have to remain at a consistently good level throughout - they can't vary depending upon how long from the start of the track it is. I especially emphasise this, because this has been an Achilles Heel on many systems, including my own - it is not a trivial issue to get under control.

Oh dear ... shoebox sound!! Definitely system, because the background music, discussion of the system components, and incidental noises prior to the listening session proper are all clean, have no problems - the system has been twisted to sound a certain way, and the video tells you that it is completely unrealistic ...

Listen as he talks about the eq and move about the room . If that neutral in not very flat in it reflective response . Over damped uppers and a undamped mid bass . That from the vocals. System listening on the toob is not helpful however vocals are very telling . :moon:

There's the quick 'n' dirty way ... and then there's the intelligent way - listening to the clip as it downloads, within the browser is convenient, but it's like driving a car with the handbrake on, and a pile of bricks in the boot. Download the video in the highest resolution, strip the visuals off, export as a WAV - and listen to it as a high quality recording. In an ABX, :D, :p, no-one would pick it ...

Wide bandwidth sound at above avg SPL WILL overload the cam R mic , you should give it a try and see ...
 
I have posted up many sound clips already, a.wayne - in pure WAV form, to see if anyone "gets it" - have you listened to any of them? Some mentioned here, http://www.diyaudio.com/forums/blog...diophile-perhaps-just-me-has-gone-before.html, the Chopin is a bit of thunder and lightning piano - and the camcorder badly overloads in the high SPL passages, causes a severe, repetitive cracking or glitching noise. At one point a dog can be heard barking in the distance, gives an idea of the volume balance ...

I notice the LP "de-magnetizer". :rolleyes:

Hey, Short stop said they work ..... ;)

You are a master of understatement, no comment on the choice of tunes. I also notice the little trestles on the speaker cables (kinda narrow guage?)

It's directed at franky, Scott, understatement and Par is one and i did like his selection of tunes ..... :p

Panel Speaker or Monkey Box ... ? :)

Interesting that he's got the sound to match remarkably well, in that video, on that system. CD is obviously truer to what was actually happening in the studio; vinyl has lots of those rounded edges, pulls its punches on the bigger moments - is "nicer" for those who like that sort of thing ... a lot would be due to the mastering, of course ...
 
Why do they use so much "weird" music in these sorts of things, :rolleyes: ... as usual, it's all about the treble, and the piano on the Infinity showed up major problems, the bass notes were way out of kilter - but it did a much, much better job of the percussion instruments than the Focal - probably a bad mis-match there, in the latter system. A sign of that was the ridiculous spectacle of the power needle showing peaking of 1.2kW or so - yeeah, right ... :rolleyes:. If that amount of power was actually running through the voice coils the room would have been filled with smoke, with the speakers starting to catch on fire.

Yeah Frank , truer to the original ....:rolleyes:
 
Rock and pop have tremendous punch, if you experience it truly live, not though the frequently grubby PA setup, you get what the energy is about. Of course, if the playback system has distortion issues then that energy turns into extremely unpleasant, irksome SQ - not nice to listen to! Two ways of dealing with it: clean up the playback chain; or apply a very softening filter to what you're hearing - your choice ...
