Next week I go to my Asia headquarters also known as my condo in Bangkok. Bringing my two teenage girls and their mother to Bangkok for R&R and shopping with my Lisa. No father, me nor brother... all ladies event. Should be fun for all. Then go to factory and check/listen to the new high SR ultra low distortion power CFA. I shipped my QUAD ESL 989 speakers over there to use. Then its off to other places and things to do... meeting and travel around the region. Will be following this in the evenings when I have nothing better to do. 🙂

I'm very, very impressed with your schedule, thanks for sharing.

Next week I'll report for work, compile some more HDL code, generate the test vectors, and if time allows I'll run a few end to end logic simulations using these. Not much fun for me, you'll have tons of fun and, meantime, the unique opportunity to advance the DYI audio experience.
 
yes I did. I just dont believe everything I read from mfr. it came across to me as a bit of justifying the DAC chip used and its workings.

Then he says this -- "If the choice is between a CD and a DSD version, the DSD version may offer some improvement." But, I do wonder if 24/96+ HD master downloads has eclipsed both.

Which brings me back to what is the better and best way to do DSD? The unit of #88775 above might be there for DSD direct masters downloads.

It's not justifying anything. DSD is a relic of the days when 1-bit converters were a thing. The best measuring way for mortals to do DSD right now probably is through an ES9018 DAC. The absolute best? Probably Bruno's new toy if you can get your hands on one:

DAC


If you want to hear DSD "as-intended" try to get a Sony SCD-1. That was their reference SACD player. Uses something Sony calls a "current pulse" D/A converter.

Life is good for those who have few bills and retire early enough. I paid my dues also.... years of the grind.

If you use FaceBook... anyone can see what I have been up to. BTW- my girls are really not mine. I support a small family so the children can get an education. Otherwise, they would be sold or married off -- their village is a two day trek on a dirt path. Poor doesnt adequately describe the life in remote Nepal. Girls rarely get an education. I have been supporting them in Kathmandu since they started school and next year the oldest girl will grad from high school... The first in their village. Even though she now lives in Kathmandu to go to school, there are only 7 girls attending in her grade. She is planning to be a civil engineer. After surviving one of the worlds most powerful earth quakes and she was at the epi-center at a wedding (which I was invited to but didnt attend), she really wants to help rebuild and install infrastructure. And, both of the girls are incredibly beautiful as well as smart. They will have a better life than planting and watching the rice grow.

Live life to the max and dont waste your time only working for a living.

I think there is a device you can buy that you hang over your monitor to calibrate it - uses some software as well.

Getting the colour balance in a picture spot on is no trifling task.

The Pro's also use a white balance card (usually cropped out of course) that is of a known colour/tint. PS, Picasa or whatever then calibrate the rest of the pic based on that known colour.

See Scott Kelby 'The Adobe photoshop CS5 book' for example.

ColorMunki, then you have to calibrate your printed for different paper types you use etc.
18% grey works best.
I also use this for critical colour shots I want..
ColorChecker Passport - Camera & Image Calibration: X-Rite Photo & Video
 
You got it. There was no question being asked for an answer. Sometimes, it's just my thinking out loud and looking for a response that can go just about anywhere.

In the case of DSD vs CD... if BenchMark's EE thinks DSD is probebly the better of the two.... lets see what, why and where for. And, i want to hear DSD's best. Has enough effort been put into developing it to a high level of quality/performance? Or was it cut short by marketing forces? If BenchMark thinks DSD has the technical edge, who can prove he is wrong? I'm listening.

Which technology won in the market place is Not an indicator that its because of technical superiority. Rather, in this case marketing forces and finances may have caused the use of certain technologies we use mostly.

For these reasons, there is no compelling reason to pay extra for a DSD recording if a 96 kHz version is available. If the choice is between a CD and a DSD version, the DSD version may offer some improvement.

See its already been quoted, but not exactly a glowing go out and get it statement...🙂

:up:

Life is too short for anything else.

1. Take career risks when you are young i.e. up until you are about 40
2. If opportunity allows, strike out into business on your own when you are young
3. If you opt for a career, make sure you do not stay in the same job, or company, more than 3 years for the first half of your career - i.e. up until 40. If you do not move, your salary will stagnate and in most cases so will your worth to the company.
4. Only move if its up - avoid sideways - mistake many folk make
5. Network, network, network. If you are a nerd/introvert (I am) you will have to work hard at this one.

I am teaching my son these things. He is making progress.
 
OTOH you could argue I have stagnated, but I can be home in 10 minutes and get to put sproglet to be everynight. That's worth a s*itload of money.

As for point 3, my salary increased 6 fold in 10 years in the same company in my 20s and early 30s... Might have been an outlier tho.

Agree on the risks, and damnation to wife 1.0

One thing to add. PUBLISH YOURSELF: Especially if you are a working stiff now. That is the big mistake I made. I kind of knew it in the 90's and 00's; that I should have written a few articles. But I was too caught up in the rat race and family, kids... This was a big hole when I started Lounge. I had to start with no paper trail for the public to see.
 
Well my evening has been ruined (in a good way) by my boss putting me onto https://boomkat.com/ . There is stuff here that even Scott would find odd! Been sampling lots and some great stuff. For some reason very tempted to get the Daphne Oram CDs they have. Not something you would listen to regularly, but you have to go back to roots now and again 🙂

Hmm. Interesting.
