Charles Hansen of ayre thinks ALL processors suck.

But there is no HDMI D/A converter on the planet that sounds even half as good as the analog outputs of the DX-5.

So if the customer only wants it for movies, that is a great plan. For years we have all been listening to 5.1 channels of low-bit-rate MP3, and it has been just fine. The visuals make the sound quality less important for watching movies.

Until someone makes an SSP with Audio Rate Control, discrete analog circuitry, and volume controls at least as good as our $3500 preamp (FET switches and metal film resistors), then anybody who listens to music even once in a while shouldn't mind spending a couple of thousand dollars extra for great music playback.

And they will be still be saving money. To make an SSP with the features noted above would probably cost $25,000 or more. Why spend that much money to get eight channels of incredible sound when eight channels of pretty good sound is all you need for movies? Then you can save your money for where it counts -- those two channels of music playback.


Wait, his "opinions" get worse.

Yes, but where does the blame lay? I say with the SSP's that butcher the incoming analog signal in countless ways.

And how good will the HDMI connection actually sound? HDMI has far worse jitter than S/PDIF. We have never made a DAC with S/PDIF because it is a flawed format that inevitably degrades the sound quality of the signal. You can read more about this topic in this white paper:


Until such an SSP exists, the only way to get truly high performance music reproduction is to use the analog outputs of the DX-5 (or other single-box player) into a stereo preamp that has a processor passthrough mode. This will serve 99.99% of all music available today.


Of course he does not explain why, since he has not even measured the jitter in the DX-5 he is just blowing hot air.

Quote:
c) Nearly all existing SSP's are "flawed" because due to cost and space constraints, they use high-feeback op-amps in the audio signal path and single-chip op-amp-based IC volume controls. There are a few exceptions. The Theta Casablanca uses a system of FET switches and metal film resistors for its volume control. I believe (but am not sure) that the audio signal path is fully discrete, although it also uses feedback. The Levinson No.40 has a different kind of volume control. I believe (but am not sure) that it is the MDAC style of volume control that they used to use in their No.38 preamp. I am unsure of the other details of the No.40's design. The original version was released shortly before the company imploded. I have heard snippets that the version put back into production a couple of years later had some changes.

b) One can take a jittery signal, such as HDMI or S/PDIF, and by throwing money at it, reduce the level of jitter. The more money you throw at it, the lower you can get the jitter. Theta has been building digital products for over 20 years and has some of the best jitter-reduction circuitry around.

But, as I said before, that is just a guess.


Sorry charles but it looks like everything you have said is a guess.

The final thing to consider is that (to the best of my knowledge) Ayre is still the only company that provides total isolation between the video and audio systems. That is one feature that is very unlikely to ever become common, and yet it remains one of the most important determinants of system performance (both audio and video).


To his knowledge, looks like to me charles needs to do some more reading.

Maybe we will build a "transport" version someday. But only when someone (I guess it will be up to us, as nobody else seems to be willing...) offers a video switcher/scaler that offers galvanically isolated audio outputs and an SSP with the above features. Otherwise, what would be the point?


http://www.avsforum.com/avs-vb/showpost.php?p=18203168&postcount=562

Quote:
In addition, the picture quality of the Ayre should be distinctly better than other players. This is due to both the use of ultra-low noise pure linear power supplies throughout, plus the galvanic isolation between the audio and video sections of the unit.


http://en.wikipedia.org/wiki/Galvanic_isolation

Quote:
Galvanic isolation is used in situations where two or more electric circuits must communicate, but their grounds may be at different potentials. It is an effective method of breaking ground loops by preventing unwanted current from travelling between two units sharing a ground conductor. Galvanic isolation is also used for safety considerations, preventing accidental current from reaching the ground (the building floor) through a person's body.


I doubt charles knows what galvanic isolation is and used the term just to sound intelligent.

Steve, I guess my Cambridge 840C CD player is great for audio since, it does true isolated video / audio systems - it has no video) and it has no HDMI or S/PDIF jitter problems - it's a single box player! Its got the high-fillutin' analog circuits too.

I don't know what the Ayre costs.....

It's fun for the marketing types to make up silly techno-speak. After all, that's all that SACD ever was -- "Direct Stream Digital" or "DSD" is NOT an engineering term, it's a marketing term. It doesn't mean anything in particular except whatever the marketing department feels like on any given day.


Funny, since charles is famous for making up "silly techno-speak".

Yes, of course. It just adds to the cost and complexity of the system.

With S/PDIF and HDMI audio, jitter is built into the transmission link. One can never completely eliminate jitter once it's there, but rather filter it out through various techniques. Basically, the more money you throw at it, the better the performance can get.

A big problem is that some of the best techniques introduce a lot of latency, which is unacceptable for A/V applications. That is why many companies were thrilled when Asynchronous Sample Rate Conversion was developed. Data processing power has become so cheap that a chip can throw out all of the original data and calculate new data for what it thinks it would have been if there were no jitter in the incoming signal.

The algorithms work well enough to fool the measuring instruments, but the audible results are not so clear-cut. But since it measures well and is cheap, its use is becoming very widespread.


Is this guy serious? Jitter is built in? The guy is worried about increased latency yet any basic source/processor/receiver will have latency adjustments, when was the last time charles used a hometheater product? I saved the best part for last, "The algorithms work well enough to fool the measuring instruments, but the audible results are not so clear-cut. But since it measures well and is cheap, its use is becoming very widespread." fooling the measuring instruments, well folks that one takes the cake.

You still may want to get the Oppo SE. Has anyone done a comparison of that with the Marantz? Even if the Marantz is better, is it enough better to justify the price difference?


Funny, charles talking about price.

The other USB connector on the rear is to connect the DX-5 to a PC. By using your favorite music player software (eg, iTunes, J.River, Foobar, et cetera), you can turn the DX-5 into a state-of-the-art music server. You can store your music on your computer with all the convenience of playback through playlists, random play, selection of multiple tracks from multiple discs -- the possibilities are endless.


Odd thing to say after he just finished bashing every computer PC or MAC that is out there. Oh but of course his product is so good that the computer will be turned into a audiophile piece.

Quote:
That is "Digital Audio Output" on and off. It turns on and off the AES/EBU connector. If you don't need to use it, the analog audio will sound slightly better if you turn that off. It's kind of like turning the display off, or using the "Pure Audio" mode that turns off both the display and the video circuitry. The less RF noise inside the box, the better the analog will sound.

These are small differences, not huge ones. For example, we also have a "Display Off" function on the C-5xeMP. But I never use it as it just doesn't seem worth the bother to me. But if you are going for the absolute best two-channel analog sound, all the controls are there.


And I am sure he has measurements to back these claims up. Hahaha.

while charles may be a lot of things, one thing for sure is he is a competent business man and knows how to milk the well to do audiophiles.  credit where credit is due if you believe in the "let the buyer beware" concept.  double blind testing shatters all class barriers.  think of it, the people who write the reviews depend upon those that produce the products for their livings, its like letting the fox loose in the henhouse yet we all seem to play the game, and double blind listening tests would almost immediately shatter the myth of sound verses the reality of associating your ego with the cost of the products you use.

manufacturers have to make money, just some also make a lot of noise about the value of their product instead of letting it stand on its own merits against the competition in a fair and unbiased (double blind) testing environment.

my friends and i went through blind testing in the early eighties and discovered the value of it,.....it made us better listeners and better audiophiles and gave us confidence to trust our own ears and not those of the audio press.  we also found that measurements did not tell the whole story, but as long as components were nearly the same measurment wise, they sounded very similiar, but not in every way similiar.  the question always was and is, which is more accurate!

Tomelex, on a similar note, I acquired a vintage KA-7100 integrated amp (same model I had in college). Dropped it my system and had a listen to both CD and LP. All 'in all, there was not the huge drop off sound quality that I was anticipating. Makes me wonder what I have been doing over the last 25 years to improve my rig.

Seems like I really did not get that far in absolute terms. But hey, it's the journey, not the destination. In the audio wasteland, you wander around and then, eventually end up coming full circle. You don't notice it as home because it changes over time as well. Is there some deep religious implications here?  Undecided

Enough philosophizing - I'm getting the itch to mod the KA's speaker binding posts to 5ways so I can use my current speaker/sub wire.  It really is a nice amp - 60watts/DC coupled and a very smooth and quiet FET phono stage.

Hi f Cheesyrch

thats interesting but i dont think unusual actually.  i mean, a resonably designed amp from the 70's or the 10's should sound very similar within its genre (sand state, glass state, push pull, single ended, digital!?) 

for example, amps with output transformers will skew the low frequencies and help make that fat tube sound to a certain extent, while a sand state device, no matter when made, will not do that, so comparing like to like i would not expect a big change. 

i hear you are running solid state now and as i think we have both said in the past, good solid state or tube tend to sound more alike.  its the fringe products that sound different and can sometimes pull us in their direction.  also, SET is working on enhanced dynamics by design and so that should also be a stand out feature of his rig. 

the idea of a resistor buring away as heat your lowest details is catching on nowadays with transformer input volume controls and what not (although you trade one thing for another....ie added harmonics in the transformer volume control verses the faintest loss ..and arguably non audible in my opinon...of heating a resistor ever so slightly in a "standard" volume control)

also, in the old days, when one could quite easily audition products at the local audio saloon, it was more tempting to jump on new equipment you heard down there.

i remember once, when i auditioned blind cd players, i could only really hear the difference in one quick section of the song i played, and it really was not enough to select one over the other and it came down to which one i thought looked best.

the concept of burining in components for hundreds of hours until they sound right i think is a bunch of baloney.  yes, some components need some break in time, but not hundreds of hours.  whats really happening is your ears are just getting used to the sound and like all things the shound becomes familiar, just like the way you make your favorite steaks and nobody else's can taste as good as yours.  some times i think just hearing something different can be "better" if you are sort of in a positive mood at the time...that is the atmosphere and sourroundings and even the song being played and all can come into play.

i noticed that often times, when listening to some new gear and with an open feeling in my heart and money in the bank things tended to sound better too.
especially if they looked "cool".

so, i am in sympathy with what you say and also if you liked that amp then i would suspect you would like it now  Smiley 

in the end, each component puts its harmonic spin on the signal and you like it or you dont or you dont care one way or the other and then maybe it looks cool or has been hyped up or whatever. 

i can play cds that will make the best system in the world sound like trash but i cant play a cd that will make a lousy system sound great (in most cases).
for me, if you are groovin to your fav music then the system becomes less noticeable (of course we are talking decent systems as we all have anyway now, or even 35 years ago).

it is a hobby after all, not a scientific study.  although personally, i think we all like to think we are progressing in our systems resolving powers (i mean strictly frequency response not ability to discern quality playback) meanwhile our ears are resolving less and less as we get older.  we change and our systems change and along the way hopefully our toes are tappin and we are jammin to the tunes.

i am an instructor for my company and in the recent class we had young technicians and one guy aged 28 had never heard of supertramp, so i turned him on to the 4 cds i have and he copied them.  funny how soon groups are forgotten to the next generation. 

anyway, enough waxing poetically for tonight!  cheers!
