The Black Hole......

From the list that Braca suggested, I've taken a part of a 96/24 track.

There are 3 versions.
1) the original 96/24
2) the original BW filtered at 20Khz but still as 96/24, and
3) version 2 but now limited to 16 bits also in 96/24

The 3 files are in random order in the dropbox file below as A, B and C.
Let's see what you can make of it.

Dropbox - DiyAudio - Simplify your life

In order of preference...

B, is best, cleanest, most dynamic.
C, comes in second, with a little less dynamics
A, worst, sounds muddy

If I had to guess which is which....

B, original version(1)
C, version 2
A, version 3
 
It looks good. THx. I have comparables now but not all in one like the legacy.

I know the mini dsp SHD isn’t in the performance league your after, but general consensus says it’s much better than the 2x4 stuff......I’m seriously considering one for a biamped 2 way setup, basically because it’s the most I can afford. Have you heard good,bad, or indifferent about the SHD?
 
My opinion only:
Given the CD recorder's age IMHO it is doubtful its data converters are up to the finest performance levels. I would want to put it up against those used by guys like Bob Ludwig and compare the sound.

More opinion:
What makes me think the above is my work with DACs (and ADCs). The best I have gotten out of a CD with AK4499 is very good indeed. Doesn't comport with my prior impression of sample rates such as with the very good-measuring Lynx II data converters. Its ADC/DAC loop clearly sounded better at higher sample rates. However, the more professional level 'Crane Song HEDD 192' ADC sounds about the same at all sample rates, more in keeping with what theory says should be possible.

Ney. I dont use it to listen to it with. Just to burn the CD to standard.

The difference with analog master tape was way beyond subtle ADC/DAC differences at 16/44.

I'll leave the door open to the possibility things have got better for CD. But, not Master level better sound.

‘Good enough’ is the term I keep hearing, I’m with Richard.....why settle for that?

For domestic replay there's little evidence that any more is needed. Certainly there are very few recordings (if any) that push the 16 bit dynamic range and most hovver around in a compressed space.

Given none of the studies have shown a clear ability to discern or prefer hires it's therefore worth discussing. Let's see if many people will do Hans' latest test. It won't scientifically prove anything, but will be interesting nonetheless
 
Howie - "properly executed digital storage of 16/44.1 only compromises some" ... "Of course DAs and ADs with good filters like the Apogees are necessary to keep from mangling"

Having experienced a "mangling" effect imparted by particular hardware, I have to believe the rest of the electronics has more to do with good sound than merely the sampling particulars. It seems we've assumed that part's all transparent in the discussion - while anything different in the electronic makeup of that which surrounds the (AD / DA) converters is probably as significant as different source masters.

Certainly other parts of the audio chain can cause problems. I am only addressing the discussion of the different consumer delivery media formats.

Cheers,
Howie

I have their best model. have not used it yet. It needs an input filter and jumper out the polar input caps and outputs if there is no dc offset. Thats the easy improvement. The software is easy to use.

I have the CX-3400 because I can also adjust delay between the 2 speakers. Cost is about the same. bal/in-out is there if you want it, too. They use better opamps in their other models i have. But, will check it. .

Bill, apparently there aren’t many people that listen to music at the levels I enjoy, and to tell you the truth the differences aren’t really that apparent to me until it’s cranked up.....now on the flip side of that, when my system is dialed in for loud it ‘usually’ translates to better at low volumes also.....more of an ease to it.

I hope I pass Hans test......my street cred will drop considerably if I flunk it! 😛

Cymbal Reviews with Spectral Analysis | Drummerworld Forum

The fundamental and first harmonic are within the legal frequency FM transmission range. However having a spectrum analyzer and looking at the commercial FM stations, one can identify when the Federal Communications Commission folks are in town and checking up on performance. Otherwise I have seen as much as 250% modulation.

The station in question was tapering off around 5,000 hertz. Too much level into the link was causing compression after the high frequency boost is the most likely culprit. That would have been done at the wrong stage of the broadcast signal chain to make things sound louder.

(I was once in a local FM station's chief engineer's office when he got a call from a friend telling him the FCC was in town!)
 
MiniDSP SHD looks to be about the same as the DSP in the Crown amps for JBL M2s. 24/96 Sharc processor with less than top of the line AKM data converters. Clocking is probably not spectacular either (sharc can be good, their ASRCs are not the best IMHO). Not sure it would be an upgrade.

Dont worry, I only have some funky in ear things and an All-in-One desk top computer. Hardly my best quality system. Maybe medium rez? We both agree on A being worse.
I might say C and then B.

Wish i had a better system to tell difference mo-betta. Maybe others do and will let us know.

BTW, I like it on the louder side also because I can hear deeper below the max.. flattens out the Flet-Mun curve.

I already decided after looking inside not to use it. Too many hardware compromises. Thanks for the extra info. I agree it isnt an improvement. But being able to use different power amps should yield greater improvement, also. The distortion isnt really that low with Crown 'digital' amps.

You dont see a connection with 2 samples and CW. Its in the def of NYq. CW.

Every def I found makes it a point to say for a continuous signal, then you can get away with as few as 2 samples per cycle.

Maybe its just me.

What do you think a continuos signal is? Its someting that continues, no discontinuities. All music is continuous, even in the silence the signal continues with a value of zero.
 
Yes that’s kinda the impression I’ve been getting on the SHD that the dsp is good but the dac/preamp section is a bit inferior, they do make an all digital version of the SHD but I can’t figure out if one stereo digital input results in getting two stereo channels out or if you need two digital input to do it.

Edit...Looking at it closer seems as though one input gets you two out.

I could use a separate dac to run the top end. That might be my most cost effective choice.

I see, thanks. What’s the fine in case they are caught?

Btw, a lot of high sampling rate (176400Hz) cymbal wav samples here, download and do your own analysis.
