Thinking about getting a R2R DAC

Dear community,

I currently have a chord qutest DAC. I like it a lot, very full sound, accurate detailed and exciting.  However, whenever I go back to vinyl (with a well-recorded nice pressing) I find the sound so much more satisfying.  There is a warmth, yes, but there is a presence, a 'there-ness' that I just don't get with the digital.  I'm wondering if an R2R DAC would get me closer to that?  my budget would be around the same as the qutest.  I was looking at the MHDT Orchid or the Border Patrol.  Don't get me wrong, I really like the Qutest.  I am thinking of putting it in the upstairs system to pair with the Node2i I have up there.  Any thoughts?  Will analog always just be a different animal than digital?

Currently in the main system I have a Sonore uRendu feeding the Qutest which is going to a LTA MZ2 going to a Pass XA 30.5

thanks!

The problem is a simple digital oversampling and anti-aliasing filtering (used in most DACs) is not accurate enough for music reproduction.
DAC without oversampling and Chord DACs with sophisticated oversampling and anti-aliasing filtering solve the same issue by different approach. The goal is recovery the original analog signal that was before ADC.
So one solution it do pure analog low pass filter.  Other solution is to do sophisticated digital signal processing using modern powerful FPGA and smart algorithms.
The question is what does work better?

I had a Denafrips Terminator (r2r) and recently upgraded to the Terminator Plus.  I have had a Yggdrasil (r2r) and W4S DSDSE v2.2 (ds) dacs and the Terminator is in another league.  FWIW I felt the W4S was the better dac.
I added the Denafrips Iris DDC (USB to I2S converter) to try the I2S on the Terminators, the Iris was a game changer in my system.  Denafrips considers the I2S the best input but have put a lot of work into their USB input.  I wasn't expecting much from the Iris as the USB from my Innuos Statement was supposed to be amazing (and I thought it was).
I have clock cables on order to clock the Iris with the Terminator Plus's OCXO clock.  I have read the benefit is significant.

Lots of interesting views in this thread. Modern DACs have more than enough resolution in their digital filters to reconstruct the signal at higher sampling rates, well beyond the analog performance.  NOS DACs are not accurate. They used to have wicked phase issues due to the analog filters now they just have wicked aliased harmonics. Pick your poison.   A DAC can have a "voice" if you want that sort of thing. It can also be accurate. It won't be both. Buy what you like. Some of us like accuracy. Some of us don't. Many audiophiles claim to like accuracy but don't really. I would say the majority don't and would not know it if they had it, but claim to seek it out.

No doubt you realize some NOS DACs are capable of 24/192. Are you saying these DACs suck as well?

What happens when you feed them 16/44.1?


Or are you assuming the music is already upsampled as the vast majority of music is not native 24/192. Not just upsampled but filtered as well.



There is not much justification for NOS. None really except for personal preference for artifacts.
