I know that digital audio is kind of an us and them topic. I'm curious as to where all yuze gyze land on this topic.
I think a lot of this comes down to listening to music for pure enjoyment or getting ALL THERE IS out of the data.
Speak!

Hiya, Dave!
I'll <sort of> answer your question.
Much of my music listening is streamed. I use streaming to discover new music, and to enjoy 'found' artists' music. When I want to really get into the music, I listen to physical media. I've been worrying less about critical listening and more about just enjoying the music. My favorite DAC is limited to no higher than 96kHz, so I usually listen to Redbook quality.

Hi, Mike. Good to see you.
I've got several DACs (mega modified HRT Pro, Schiit Bifrost & Yggdrasil) and I stil keep going back to my hot rodded Tranquility DAC because it just makes music. That ancient TDA1543 with the mods Eric and I came up with are just my goto, could be my ego 😁. Of course I have 75 year old ears, but so what? I love me some toons.

What model Yggdrasil do you have?

What model Yggdrasil do you have?
The original... not the + . It is out on loan because it isn't my kind of thing and it deserves to be used. It is a very good DAC.
I also have a Soekris 1021 R2R kit that I haven't had time to finish due to everything going on here.

The "original" was upgraded years ago, before the +, og, mil, lim. If your serial number begins with "A", there was significant upgrade to "B" serial number.
Also, what input do you use?

Well, since I build USB cables, that would be USB. Optical sucks, AES is a flawed method, SPDIF over RCA doesn't sound right and I don't have a source with BNC. My source is a modified MAC mini with a dB Audio Labs OS. If it had an HDMI input I would be interested in trying that, but my friend Greg would be sad to give it back. :lol:

@P.I.
EDIT: I see you recognize what I stated and have corrected your post as far as where to place your text.
I'm assuming this is your last post: (you encapsulated a series of quotes inside other quotes so your reply does not standout).

I figured you would be using USB, given the "hot rodded" (whatever that means you had done, likely upgraded caps) Tranquility DAC.
O.K. I was just curious. Not wanting/looking to debate or be argumentative. But the "A" serial number Yggy you bought if original (2015?) likely didn't even have the Gen 5 USB card. So today's OG Yggy (which would be serial number B had you upgraded the A, i.e. the analog board itself was upgraded) also contains their proprietary Unison USB, supposedly the greatest thing since sliced bread as far as USB is concerned. Or so claim the Schiit fan club and those who have used it, reviews, etc. I wouldn't know as I don't (no longer anyway) use USB.
To your statement that "AES is a flawed method", again, I prefer not to debate or be argumentative but suffice it to say I adamantly disagree and in fact believe it to be the **very best** of digital inputs one can use. Even better than I2S/HDMI, which by the way is not completely standardized.
I'd be interested in reading any citation you could post supporting your claim "AES is a flawed method". Prior to Unison USB, Mike Moffat himself claimed AES/EBU to be the best digital input, and not just for Yggy.
Optical too can be very good if done right so I personally wouldn't go as far as stating it "sucks". I use optical from my LG C9 to feed Yggy and it's entry level optical cable and still sounds grate. Glass optical is best (of optical) but who can use that from a practical perspective?
I use SPDIF RCA on my main transport Oppo UDP205 (99.9% of listening) only because it doesn't have AES output, and AES output from my ERC3 in the off chance I happen to listen to a CD (almost never).
Happy listening. :)
Best.

Speaking for myself, I can't reliably hear a difference between Redbook and hirez formats
with my current DAC, Auralic Vega. There are a lot of ways
D to A can wrong.
You can loose what differentiates Redbook
from hirez in the DAC itself or in the following analog gain stage.
I'm sure many more sources of degradation will occur to the members
of this site. I would like to believe that the differences between Redbook
and hirez sources is as large as that between CD at 1411kps and 320kps.
In my system this difference is audible but subtle. So far I have not been able
hear a difference of this magnitude between hirez and Redbook. I blame the
DAC I use but I kind of quit chasing perfection a few years ago and settled for
good enough. No regrets. :D

My thing is that I have about 3TB of Redbook files! I'd rather fight than switch! :rofl:
-
I'm happy to go directly to the point and spirit of this topic, having to do with 16/44.1 (i.e. Redbook) and resolutions greater than that (i.e hi rez).
My thoughts are I prefer hi res and believe it sounds better....not a world of difference, but rather subtle.
If you have an opportunity as I do to collect/have multiple sources from the same artist's show or even studio mix, then "look out cause here comes some free advice" (Grateful Dead term, Bobby) and "do yourself a favor" (Grateful Dead term, Jerry) and collect/have both.
Bottom line is they are *different* from an objective perspective. Whether or not you can hear a difference, your system is resolving enough to reproduce the difference, or you simply have a preference, is irrelevant.
Best.

Now that you mention it I have about 1T of Redbook and 2.5T of Hirez recordings. I haven't chased after Hirez duplicates of my Redbook music. I have purchased non-Hirez remasters of Redbook albums that have resulted in welcome and sometimes dramatic improvements in resolution and enjoyment. The only problem I have in seeking out Hirez duplicates of my existing Redbook recordings is assuming that positive differences I might hear are solely due to the differences in captured data and frequency response limits between Hirez and Redbook. It too damn easy to tweek the recording to sound subjectively better in the studio. I am also something of cheapskate.
What is interesting to me that numerous recording artists have complained that the CD version of their
recording sounds like crap when compared against the the Hirez master and they weren't happy about the
fact that the recording to be released for public consumption didn't represent their artistic intentions.
This makes me wonder just how much of their dissatisfaction is due to the "failings" of the Redbook medium versus failings at the studio level regarding final mastering decisions for CDs.
When I mentioned difficulty in hearing the difference between 1411kps and 320kps this was
in the context of a aural training course. It strikes me now that comparing the two formats with the same music selection is also a good test of system resolution which also includes the listeners hearing acuity,
which, to a degree, can be improved by ear training.
The name of the online course escapes me at the moment, but I am sure that more than one such online course is probably available at this point in time.

I'll let you know when I hear something better than my 1543 DAC. I'd like to hear some of the Abbas DAC's.
Sometimes high res sounds different but better is not the same thing.

Dave,
I must agree with you about the Tranquility SE DAC. I credit it with turning me into a NOS DAC lover. However, my addictive personality has led me to buy too many DACs :duh, so I may end up letting go of my Tranquility SE this summer (to be determined).
My in-laws' health is precarious enough now that Melody and I may end up moving back to Taiwan to oversee their care. It's turning out to be a repeat of what happened with my parents before they passed away - only this time I'm not the person who's being devoured by the stress.

Have you been following the Abbas thread on What's Best Audio?
https://www.whatsbestforum.com/threads/abbas-dac-2-1-se.31754/#post-708536
Honestly, if I hadn't bought 2 DACs last year, I wouldn't hesitate to order a 3.21SE to compare against my SW1X DAC III+. Alas, even I have limits on how much excess gear I can buy.

Hi Michael,
Sorry to hear about the declining health of your in laws. My wife and I took care of my mom. I’m quite grateful that she was there to help me. I’ve read your posts about various dacs. I’m presuming you’re using the latest Sw1CZ sp? I’m a happy camper with 16/44. All the music I have is that resolution and virtually all the music I stream is 16/44 as well. My Border Patrol dac is only 24/96 capable and can resolve very, very well as I found out when auditioning the Hapa Silver ICs. I will admit I’ve always been curious about upsampling to DSD with a Chord Hugo M Scaler, but their stuff is really pricey and I doubt I’ll ever try one

My latest DAC is using the AKM AK4499 that is a 32bit R2R balanced ladder DAC with minimum phase filtering selectable. Sorry, but non-causal filters like linear phase give me a headache listening to digital. I think this is a reason folks like the older DAC's as they preceded linear phase filter use.
I like it more with a Class A biased output stage, but the Topping E70 Velvet sounds really good using the fully balanced output. I know some do not like fully balanced, but that would not be me. Lower noise and distortion from my listening.
The dspNexus 4x8 is supposed to get an upgrade to AK4499 DAC's at some point. Those will have a Class A biased output stage that a prototype used that beat the sound of the E70V. Until then the AKM AK4493's sound really good.
I listen to everything from 16bit/44.1KHz WAV to 32bit/352.8KHz DXD files, so I want a DAC that can handle it natively. Even digitized vinyl sounds good to me, so I am happy.
Just my $0.02

Actually, I'll see your .02 and raise you another .02. Forgetting for the moment that there's essentially no such thing as 32bit recordings yet (albeit mastering, yes) the/your key is you've avoided delta-sigma chipset in favor of multibit/R2R.
Oh, jest I forget it's not about the chipset, but the "implementation" and everything else...
Happy listening. :thumb:

The major Tranquility mods are:
Furutech FI-06NCF IEC
Fred diodes
Increased power supply capacitance with a final supply stage of PP capacitors
Much lower noise voltage regulation with voltage increased to 7.8VDC
Select TDA1543 DAC w heatsink
Upgraded local bypassing at the DAC
Texas component TX2575 bulk metal foil I/V conversion
A redesigned analog output stage using lower noise, higher speed transistors
Film and foil output capacitors
ETI RCAs
Mass loaded chassis and circuit board with ERS cloth applied in some areas
The flaw I mentioned about AES/EBU is the lack of acceptance and implementation in the high end audio industry
My biggest issue with optical is the still widespread use of plastic instead of glass fiber and the wide variation of transmitter and receiver quality.
The Yggy is a fine DAC, even in the original implementation. The one I bought does have the Gen5 upgrade board. The difference to me is the Yggdrasil SAYS" Listen to me." My outdated dinosaur Tranquility whispers "listen to me." It is the difference between clean, clear detail and musical seduction.
You do you. I'm happy.

Huh? It's (XLR) predominant. :o

Agreed. Fair enough. :)

Fair enough. To quote Jason Stoddard "All of audiophilia is a search for the perfect distortion profile." 8)

I did development work for Eric Hider at dB Audio Labs. He wanted to se just how far we could take the DAC through upgrades. Each upgrade was done independently and we carefully listened to the improvements. We also tried some things that were just lateral moves, too. I guess that you are unaware that I am/was an independent consultant/ OEM for some companies. I also have a lifetime of experience in the recording arts, so I get the XLR thing. I also know that Bernie Grundman Mastering Labs are all single ended because it sounds better... to him/them. For me, it is more of a simplicity issue. KISS is my thing. My longest runs are all < 1m, except for USB which sounds best at 1.5m.
Stoddard is absolutely right. :thumb:
-
GDHAL,
The idea behind the 32bit DAC is to make a very good digital volume control with 0.5dB steps. Not really for 32bit audio.
I compared the DAC volume to the analog controls on my HPA and the digital volume control was cleaner. I am happy with it.
Implementation is everything, but it is the only DAC so far that surpasses my other reference the Wolfson Digital WM8741 DAC that has a Class A biased output stage.

With regard to "reference DACs"...
Have you had an opportunity to hear in any system - which would typically only be in a very high end system - the lampizator horizon dac?
I have.
Frankly I don't understand how Fikus does his business. Because, it's his top of the line dac, and is delta sigma.... Meanwhile, his midline dac is r2r which upon reading the marketing literature is the creme de la creme as far as he's concerned.
Go figure.
Look, I pretty much heard it all just like the rest of you.
In the end it boils down to your personal preference, what your budget can sustain, and the other hassles you're willing to go through in order to attain what you perceive to be audio nervosa.

GDHAL,
No I have not heard the Lampizator DAC's. Not really interested in them.
The DSP end with multiple channel DAC's is what I have been using for over a decade. And no, I am not talking about MiniDSP or Beheringer DCX2496. Many companies have surpassed that sound quality.
-
I have auditioned both the 5 grand Lampizator and 3 Chord dacs, including the Dave.
Going all polyprope in the power supplies of DACs makes a world of difference.
I suggest upgrading if one can.
As far as hi rez, I like it the best If the recording was done properly in high rez. However,
redbook works, and with over a billion recordings, I like YT premium because of the selections,
and cannot find most recordings on other streaming services.
I also find minimalist recordings to be wonderful.
cheers and a great Thanksgiving.

Question for you, Steve. I mean this sincerely as I do not know. Obviously my question boils down to opinion in any case. Are tantalum capacitors "better" ( again this is subjective so there's no right or wrong answer just your opinion) than polyprope?
Whether yes or no, what is the 'best" capacitor type for audio, regardless of the component, from a sonics only perspective? By this I mean forget cost, longevity of the part, whether it be an amp, a DAC, CD player , speakers, phono stage, vinyl player, whatever :thumb:
Thank you. And Happy Thanksgiving.
Hal
EDIT Google is everyone's friend...
The best capacitor types for audio circuits are polystyrene and polypropylene. Polystyrene is the first choice, but are only available in values up to . 001 uF
But prefer your opinion as my question is more pointed.
