Thoughts on a bunch of DACs (and why delta-sigma kinda sucks, just to get you to think about stuff)

This.
 
The closest analogue I can think of is Kerning in typography. The difference in distance between letters in a well-kerned font versus an un-kerned font (or, god helps us, a poorly-kerned font) are extremely minimal. But, for someone who knows what to look for and/or is sensitive to it, that small delta makes a huge difference. 


Or the uncanny valley effect:

We've evolved to be very good at recognizing the way certain things are and when they're even subtly off it can be disconcerting.

Replacement Gustard U12 still doesn't work with my Theta.  :frowning2:  I emailed Kingwa for a quote on a DI-2014.

 
Can't remember...what way were you trying to hook up the U12 to the Theta? And you did get it to work from some other source via the same input, right? My Gen V doesn't have the coax/BNC input (will try to install one myself soon), but it works fine with the U12 via AES.
 
 
Could that be the source for purrin's extra 'plankton' !? And if yes, is it still fair to say that the iggy 'extracts' more detail from music or we should actually say that it 'adds' (it's own brand of) detail !?

 
You know what oversampling does, right?

My Theta has some old optical input that looks like BNC, and two RCA coax inputs.  When I use my X5 coax out to the Theta, both inputs work fine.  When I use my U12 coax out to the Adcom or Audio-GD it works fine.  When I try the U12 coax out to the Theta, it doesn't work.  :-/

@ Sonic Defender,   Maybe I did not make myself clear. Not being able to locate a Theta DAC I had a chance to listen to a Bryston combo and I liked it very very much. I have not heard a Theta and was hoping someone on the forum who has heard both could briefly describe the difference. I want to buy a really good DAC that I will not need to upgrade. It must be a real improvement and step-up from the Oppo, but I can not afford a new Yggy.__

What's wrong with Delta-Sigma DACs again?

Did U hear a Geek out?

Did U order a yggy?

I tried (& compared to HUGO)  during 2 weeks at home the ARM DP777 SE and tried during few hours the NAGRA HD DAC.   Next step is to compare it to the TotalDAC D-1 Dual...

I have little respect for DAR over the years - look at what they wrote. Anything substance?


It's just an early intro piece, guess we can give him some slack. But there is another gem in that article that made me scratch my head.

Another big influencer of sound quality is the digital filter for which, the Indiana Jones of digital audio that he is, Moffat journeyed back through Western Electric’s archives to 1917 for maths would ultimately beget a “unique closed-form digital filter”.


Nice indiana jones story but 1917 was an early age of analog audio. There was no digital, no DSP and barely any math involved in audio (prolly nothing more than ohm's and maxwell's equations). So what is all that about?!

Once upon a time, in the US there existed a monopoly called Bell Telophone Company.  They created Bell Telephone Labs as a "think tank" subsidiary.  This entity developed virtually all valuable audio technology in the early 20th century, manufacturing much of it by another subsidiary called Western Electric.  What is lesser known, particularly among those of limited or glib knowledge of audio technical history, is that Bell Labs developed and patented what later became known as sampling theory and the fundamentals of what became digital audio some 70 years before the fact of realized equipment; this in the era of World War One.  Bell labs published a forgotten time domain multirate digital filter in 1917 at a time when  no hardware existed to implement it.  I spent five years of my life figuring out how to combine this with modern frequency domain filters.  The resultant filter is the DSP cornerstone of all Theta and now Schiit filters. One has only to peruse the footnotes in modern DSP grad school level textbooks to verify this.

I've read about 100 pages of this thread and the thought of this "being a marketing thread" never crossed my mind. To me, it seems more like an enriching forum filled with open minded people who can support each other with the coolest DAC gear advice. Us head-fier's are not paid, we just like to share Schiit that's too good to keep to ourselves. Another good related thread can be found here. How many pages (recent section) of this thread have you read?

Hi i think that there is a consensus about them sounding flat and unexciting, lacking from a dynamic point of view.
I read that they have traded resolution for dynamics
Unfortunately i have not been able to listen a good multibit dac carefully (they are old, rare and still expensive on the 2nd hand market. A sign of quality i guess).
But a simple TDA 1543 gives me some excitment really.
Let's see when the product will be more widely available and reviews will arrive
kind regards,  gino
