I currently have a Buffalo II DAC (ES9018 chip) on a temporary loan thanks to very kind friend (Thx Antonio ) for a few weeks and have been enjoying DSD, both native and PCM realtime converted to DSD128. Wonder how many people have had the chance of listening to PC based native DSD files. Anyone?

I have a "secret" plan too I've always thought there is no reason why one could buy very good performing PCM DACs at very reasonable prices but in order to enjoy native DSD one needed to spend much more. It makes no sense. I came up with an idea a while back but couldn't put it work on my own beacuse I don't have the rquired knowledge or skills. Now I have found someone else interested in my "idea" and willing develop it. ATM it is only beginning to take shape and it'll be quite a while before there is anything "solid" to discuss provided it doesn't stall at some point for whatever the reason. It is great fun and plenty of very welcome learning involved abut a areas I know next to nothing about. Thankfully there is no shortage of patient, generous and kind people willing to help or advise, including Mr. Solderdude himself.

Sounds all very interesting Javier. Can I remind you that, when you get the little board from Scotland, you might want to think about whether our friend can help with his contacts and skills. Just a thought . Dave. PS I am literally 'getting my coat' now . BTW, when I said 'I have plans I meant that I have plans to get the facility to enjoy DSD music, of which you are well aware - nothing secret. And if you had not already realised, I do have Internet access here, despite the fact that it was not mentioned.

I like this Archimago fella. emmm..... I meant I like DSD (whistling smiley N/A). In most cases DSD makes sense from a theoretical POV as most recordings start their life as a SD stream, not discussing its potential "audible" benefits. It'll make even more sense if it could stay all its life within the DSD domain up to its conversion to analogue again. BTW, he forgets to mention DST when talking about file size, it can compress DSD by quite a bit. With higher DSD rates ultrasonic DSD noise becomes less of a problem. A few days ago Piramyx announced version 8.1 of its software that allows DSD256 recording and processing and, IIRC, Korg also has some DSD256 capable recording ADC. I find interesting he has a BDP-105 (1,200$) when the BDP-103 does the same but is much cheaper at 499$? The only difference between both players is the analogue audio section and the 103's audio is already more than good enough? isn't there some sort of contradiction in his arguing against HiRes PCM or DSD?

Some say there is still benefit even in DSD512 though probably the law of demising returns applies here big time, not to mention file size with such extreme sampling rates not matter what DST compression.
I DL'ed a free DSD256 sample from a Japanese site but can't get it to play properly. I think Amanero's ASIO drivers and/or firmware is not fully compliant yet, I get too much stutter and drop outs but we are talking 11,289,600Hz sampling rate at 1bit.
BTW, I'm returning the Buffalo II DAC to its owner this evening or tomorrow the latest so no more DSD for me in a while. Pity, I was also learning a lot about software mode and I2C commands.

Build a DSD DAC yourself .... Once you have retrieved the stream from the USB it will be easy.

Guess which one I preffer?
PS. DSD needs a +6dB boost to equal PCM levels, hence the lower max peaks, but such increase can cause clipping so not recommended.

What a proper mastering job won't do...
What happens if you convert the SACD layer (analog if need be) to WAV 16/44 and run that one through DR ? You should end up with the same DR... even when converted to MP3-320 you still should end up with the same DR.

absolutely.
Just wanted to show how some SACDs are better mastered than CDs.
