Subscribed. Was going to get a Yggy but wanted a dac that could also do DSD since i upsample everything with HQ Player. Curious, what hdmi cables are people using?
I can't quite let go of my Spring Holo DAC Level 3 just yet. Needs 300 hours burn-in.Perhaps Kitsune could get you one for your shootout. I too would love a compairison between HoloDac and Yggy. I was looking at the Menuet also.
That would be fantastic, especially when you include some 'non-Yggi' DACs. It looks as if the Yggi is the reference DAC to compare everything else to. I'd be particularly interested in the Metrum comparison, as Metrum has built quite a reputation over here in Europe. BTW, isn't the 2Qute a Delta Sigma DAC? Anyway, I'd be vastly interested!
I've contacted Kitsune so we'll see. The Menuet will come my way for review, they only question is whether it'll be here at the same time as the Holo (if I get one lol).
The Chord stuff all uses custom FPGA chips, which I've been told aren't D-S. *shrug*

The FPGA is used for the WTA filter (Watts Transient Aligned filter) among other tasks in the Chord DACs. That's where you find those loooong TAP length filters and excellent transient response algorithms. The actual digital to analogue conversion is done with the Pulse Array DAC (Rob Watts' DAC he invented some time ago, before the Hugo) which is different from traditional DS DACs. The Chord DACs are at their core principle DS, but they are taken to a degree no other DS design has gone before and they correct for many of the shortcomings of DS DACs. The theory of DS is a good one, but most implementations are mostly half-assed with cheap chips, yes, even Wolfson, ESS, AKM, etc., are inexpensive chips with far less processing capability.
I love me some good R2R so don't think I'm a DS fanboi. However, after reading threads like the DAVE thread it's quite obvious that Rob has taken his (theoretically DS) design to the Nth degree. In that sense it isn't like any other DS chip (or PWM DAC) out there. Quite different.
Apologies for posting this in the Holo Spring R2R thread, which looks like an amazing DAC by the way, but since there are some questions about it these links can provide some answers and hopefully help prevent this thread de-railing further from speculations about Rob's DACs. Rob talks a lot about his tech so the posts may be long winded.

@bimmer100, if you think this post is inappropriate in the Holo thread I will edit it. Let's get back to the Holo Spring R2R DAC!!!

This Holo DAC looks very interesting.
From what I understand : a FPGA is a programmable processor, and you can use it as well as the main processor in a R2R DAC or a Delta Sigma DAC.
If you do a search on the net you can see several projets using a FPGA as decoder in a R2R DAC or a Delta Sigma DAC.

If I get a review unit in, I'll be comparing to the DAC-19, Yggy, 2Cute and possibly Metrum Menuet. Might make a big shootout of non D-S DAC's...
Soekries DAC OEM
Are you saying the Holo is based on the Soekris board?
