DSD128.. Doesn't that about 21 bits in old money?

I wouldnt know but I said... they are giving us all the options to play direct from the source.

[But even 21 is better in reducing distortion at typical levels than 16. However, I never listened to DSD before (have i?).]

32b WAV is a gooder source file.

:cool: I hope the 8 bits not being used now (?) will be useful some how down the road. What is the reason they have 8b of padding at this time?

There are no A/D's of any technology that do better than 21 bits or so at any level, top pro studio equipment included. Marketing only. I lost a nice interview with Bob Ludwig arguably the best living LP mastering engineer, he uses the Pacific Microsonics (~a real 21 bits). When he masters for independent/small labels and the corporate interests don't interfere they are super-disks even at 5.99 MSRP.

No Nepal, we don't want to do the altitude acclimation or take the drugs used to speed up the process.

EDIT - Tried the boat noodles yet? My sister chickened out, "you mean those folks that row up to the dock with a big pot of brown mystery liquid".

I know its a hard thing to do... making the jump all the way from LP to CD was too much and now dragging yourselves kicking and screaming into todays' HiRes digital sources/systems......

But, some of you did it once and you can do it again. :)

:cool: stuff.

Richard, I'll give you 10 ... no, make that 11 points for tenacity ... ;).

Everyone else, no need to get fussed about this - hires source as a means of achieving convincing sound is a dead end; OTOH, hires playback manages to skirt some of the issues that often plague digital sound, and may be worthwhile pursing as a means to an end ...
 
So the question in many of these exotic locations is what are they using to cook, the local water I would imagine? I've had a bad experience here in Hawaii with tainted water, don't drink out of any stream or even a running waterfall, you never know what was up the source of that water, pigs, goats and other wild animals don't care where they relieve themselves.

Seems like talking about anything over 21bits of true resolution is a figment of some marketing departments. I will take Scott's opinion on the fact that no A/D converters are made to work above this bit rate as the final answer to all of this. Kind of like saying I need a 128 bit system to really enjoy reading some website, of course the resolution of the type will be so much better!

Well, we have to call it by what the company calls it... 24bits. but if we only get a couple bits less... so be it. I'll take 6db more distortion reduction. It isnt costing me anything, really, to have more bits.

Combined lower distortion with no CD burner and no CD player spinning off the numbers is also worthwhile to delete. All together, a noticeable audio improvement and lower cost and less physical space used. Less plastics etc consumed and stored.

We still need more bits to lower distortion.... even if they run down into the noise for some bits. So what if we loose 8 bits.... if the majority of the music/sound has more bits to work with? Up the average number of bits being used. As long as the dynamic range isnt compressed artificially to a narrow range. I would sacrifice (only if I had to) some dynamic range for over-all lower distortion.

What!!! I never ever took any altitude drugs and do just fine. You'll be OK.

The only time I had a problem with altitude was in the high Andes of Peru (above Cusco) and descended too rapidly by airplane to sea level (Lima). Almost killed me.

But you wouldnt be building in very high altitude in Nepal.

I was planning on you helping me build my house there also. Skilled labor is hard to find. I am looking for property right now.

That is the 'oil' i refered to. Fish oil or worse. Developes an unusual flavor after many different foods have been cooked in it. It gets used over and over.... Might even be engine oil for all i know. but, yes, ate those noodles and other foods many times. boiled is boiled. They cook it in the same oil in the cities and on the street. I never eat off the street though.... I think in the 15 years i have at there and continue to eat out.... only got ill twice or three times. Just be careful what you choose to eat and sometimes where you eat. The larger hotels are safely prepared.

just refilled the bottles.

First time I got the advice not to buy bottles with a broken seal was not all that long after losing my virginity. (I plead guilty to a pre-puberty offense)

On hot days at Curaçao, there's a nasty fat guy sitting at the end of the pontoon bridge in the city center, selling 17oz refilled water bottles from a cool box.

Perfectly safe to drink, tap water is 100% OK there.
But if you ask him what a bottle costs, he'll say 2 NAF, which is a dollar twelve.
If you ask the price in US currency, he'll say 2 dollars.

At less than 100 yards from where he's sitting, shops sell bottles of mineral water with unbroken cap seals, for 2 NAF.
 
abraxalito has just mentioned the new Schiit DAC in his blog, and this review gives a nice rundown of what all the "excitement" is about - particularly of note is the ability to "handle" "poorly mastered, old blues, 16 bit recordings" ... :p.

The bit that will drive the objectivists bonkers is the 6 hours warm up time, :D - ahhh, been there, done that ... ;).
 
Richard,
I don't think I need a picture to understand the sanitary conditions. I wouldn't say it is much better in much of Mexico, just go down by the beach near any cliff side restaurant and look at where the effluent is going, never would get in the water around that. I wouldn't trust anybody in those countries to wash their hands or anything else for that matter. If I didn't prepare the food myself forget it. There are so real great water purifiers on the market now, You could get all the clean water you want with them. Costs a couple hundred dollars for a good one.

True stories of a traveler -

Richard,

I have a time-share in Porto Vallarta, Mexico. Nice art community there. It's brand name bottled water only IMO. But they do a better job of getting the hotels to treat the water somewhat and also before they dump it in the ocean...... there's a good reason the hotel is next to the beach but everyone is swimming in the hotel pool and just looking at the ocean.

But for drinking you need more than clean looking, filtered water.... you need it to be bacteria and germ free, also. That costs more. But I am tired of buying and carrying bottles of water back to my room.... so in my Bangkok Loft/condo, I will install a mini-water treatment system under the sink that cleans/filters/ and disinfects the water.

True story -- I went to a remote island off the coast of Thailand and Cambodia... its called Elephant Island by the locals. Only a single dirt road that makes it half way to the other side..... unusable in rainy season... just mud. All dense jungle growth. but anyway, I went as far as the road took me and there was a village there with a restaurant of sorts. A fishing village. This should be great for fresh sea food. It is located out on the end of a make-shift peer. I asked where is the bathroom..... it was just beside the walkway going out to the restaurant/dinning area over the water. It was an outhouse where everything just dropped/dumped straight into the ocean water. Now, the fish which are caught are kept alive until eaten in an underwater net. About 15 meters from the outhouse. The fish tasted good though. What are you going to do... starve? --- far from land and no boat back for a few days.

I am , too.

In "digital line stage" , they are like the PPM amp people :eek: and
are at the 32 bit DAC level now !

Another "who's is longer" type thing ?? (I understand - nature of the beast)


OS

There is more to it..... Take a look at BenchMark-Two and how they use the multiple 32b DAC and DSP to get more dynamic range and lower distortion at mid and low level (detail, clarity, realism).

-RNM

besides issues like down conversion errors from 24 to 16 and other issues like jitter and so on..... One point is --- A simple distortion comparison of any low level 16 bit and 24 bit is what seems to me make a difference/improvement that I easily hear.
