How to get into high end digital? (Feeding a DAC)

@audiotroy There is a lot of misinformation here the quality of the data stream really matters and can totally affect the sound quality of the dac all dacs are sensitive to jitter recllocking can help but digital noise can not be reclocked out.

What exactly is digital noise?

I see this: https://www.audiosciencereview.com/forum/index.php?threads/dac-vs-cd-player-shootout-measurements.10...
which seemed to above 20kHz, but it would not help anything.

OP you are getting advice from jasonbourne and his ilk which I suggest you completely disregard if you are after 'high end digital' That poor horse has been beaten to death.

I try to appreciate all perspectives. And appreciate them more with soom back up evidence. And I would still like to know how and what people that design cable get good, or bad, cables from a scientific perspective. Not everyone is J.C Maxwell, or others, but the physics is not different for different people… It is universal.

You also mentioned something about measurements. If you are not familiar with digital then ignore the technical side and use your ears. Somebody gave the impression that R2R is baggage which is not true. Don't worry about the architecture just how it sounds. I have an ancient baggage machine, a Wadia 15 that is so full of baggage that it can only play redbook, but outplays my Bryston DAC even when the latter is playing hi-res. True story. The measurementalists frown when I explain that I prefer listening to ... music, not so much interested in how sine waves measure or sound.

I basically do not want an embarrassing CD play and disappointing experience. Currently I was not sure whether the old CD player or the RCAs had the blown channel… but I put the AQ Emerald interconnects on and it sounded OK with “The Violent Femmes” (Which are often recroded poorly), and “Social Diostortion” wasn’t bad.(So in my case the 1M AQ interconnects were better than the 5M store bought ones, which are obviously $hit-Haus.)

Then I put on some Vivaldi, and it is front to back and side to side… everything laid out.Then the Doug McLeod LIve the Europe…Both sounded pretty awesome.

But I am also trained and educated in science, so I have a hard time believing in the pure magic. When the McLeod song comes on, I do not want to think about measurements… and it again brought a tear to my eye. (Which is a better tear than those form looking at the empty wallet)

If the two sources sound different , then they must also be producing different signals versus time. This is what graphs, measurements, and solid engineering is for.

Whether it's analogue or digital the source matters a lot and it's importance should not be underestimated.

I hear you. I think that the speakers matter more, and I put the source at #2… but I agree.

The recommendation to visit a few dealers is solid advice and is worth heeding. 

I used to live close to many good shops, or close enough to get there in an hour or three.

Now I am literally more than a day’s drive away, assuming that people drive 1000 mi in a day… Hence I try to prefilter ideas and opinions into some plan.

It is probably similar to Covid shopping for many others in area which are less fortunate (i.e. more sparsely populated)


Anyhow I played a bit of “Immortal Technique” (Mistakes), and the “Eurasure” CD, and it all seems pretty good.
Maybe the rest of the chain of gear is not up to scratch.

But I will spend some time in (what I believe) is a decent shop in Perth… where I am flying to in 3–4 weeks.

i dunno…

I must beg to disagree with any reclocking naysayers. thought I had a decent sound until I tried a USB reclocker. Specifically, the Innuos Phoenix. Didn’t want to lay out over 3 grand wo trying first. So, I borrowed one and what a difference it made! Better vocals and sound stage. It took the edge off the highs for a smoother sound. They say that each upgrade is a small step towards better sound. Well, the Phoenix is a broad jump in my digital system. Go listen to one for yourself.

Fiber optic provides complete isolation from the noise in the power supply of the sending unit.  Coax does not.  Galvanic and isolation transformers still pass noise through the ground.  Wireworld makes nice fiber optic cables made from glass.  Although I also have others from Amazon.  
For a transport I have a Rega, Woo Audio, and Marantz.  The Rega sounds a bit thin compared to the other 2.

For streaming I use Qobuz for my IPad into an Upsampling DAC.

I’m a tried a d true AQ guy. I do use two top end Wireworld for Ethernet though. 

Forget all that stuff.  Pitch it all out and get a set of the Dutch & Dutch 8c.    Not only are these loudspeakers amplified, they have built-in DAC and DSP EQ.  All you need are them and a digital source like a laptop, an iPad or even just your cell phone with Roon.

When you set them up, you tune them for your room and you're done.   They have some of the best imaging I've ever heard, at any price.  Truly uncanny.

Now there's no screwing around with matching components, cables (you get to eliminate speaker cables!), changing out tubes...    One stop shopping for the very, VERY best audio you'll ever hear.
