Very true. Problem is the distortion and or the resampling filter is still audible to some extent or other. There may be a few choice of filters, but it always seems to be a zero sum game where one can trade off one audible defect for another. But, I am very picky when it comes to SQ. It doesn't take much ear fatigue to mask defects, either. Brains also accommodate to many smaller SQ shortcomings typically over a few days of listening, probably the main effect going on behind many claims of component burn-in.
EDIT: Anyway, if too many little defects are allowed to exist I hear them right away when I listen to a new system. In fact since we are talking about a particular application, I have been over to Richard Marsh's house and listened to his main system and his headphone system at the computer. I want him to be happy with the sound and while I think there is probably room for improvement from my perspective, Richard has his own preferences and priorities. I don't want to be a pain about it. But, since we are talking about what he might do, I would encourage some solution I would like on the assumption he would too once he heard it. 🙂

I don't know how audibly transparent (or not) the AD1896 is. If I had to guess I would say it's probably close based on the fact that it was incorporated into a number of well-regarded components including the original Benchmark DAC1. The current DAC3 uses TI SRC4392 which is conceptually similar but is probably a little better.
Yeah, the AD1896 datasheet is actually the best of the group. I found the characterization a little strange at first but I think it's described in this paper:

I am not here. I am over there. Hanging with my girl(s). I will be back on Aug 19 and soon will have two more of the stereo amps completed. They will be starting on mine next week and expedite their build because I said Mark has to hear them 🙂 Then, all those things I had in the mental pipeline will get done. We can even listen to HPA off the DAC3, too. We will also use HD downloads for music source material.
I know you are a critical and experienced listener and so I will bet you a dollar you are going to be really happily surprised at what it sounds like. Its going to be fun! , 🙂

Who wants to work with this next gen EE? Raise your hand.

An alternative is to use all material with the same sample rate, then no on-the-fly conversion is needed. You'd probably have to convert all the source material offline as it were, but that process could be highly optimised as it doesn't matter how long the processing takes?
That does work, but you'll find very few people that want to make a DAC or DSP system that operates at only one sample rate. ASRC are most useful to bridge clock domains, not only for sample rate conversion. Without an ASRC you will need a VCO + PLL, FIFO, or similar when interfacing between two clock domains such as an external DAC and recovered SPDIF clock (if you don't want to clock the DAC directly from the recovered clock, that is). So, it's quite useful if you have multiple sources like a USB interface, SPDIF interface, etc.
On a PC you can do transparent (IMO) SRC in real-time though anyway. I find Foobar2000's PPHS resampler to be fine but there are many good options.

All live in Nepal. The single photo is my girl. Her name is Sarada. But I call her Sara. And, she is the tall one in the middle of the gang of girls. 19 years old. I have been Godfather to her and family since I met her at about age 5-6. I have supported her education ever since and visit her every year and we talk on Facebook daily. She is from subsistence farmer family in very remote region -- no roads... I never been to their village because it is a 3 day and night walk one way. Not fun and no facilities in village. I have educated her and brought her to Bangkok about 8 times... she is in my condo sleeping right now. She gets straight A grades and has been accepted to many colleges... all that she applies for in several countries. She reads, writes and speaks fluent English. She is great in mathematics and science. She will be going to either Canada or Australia in a couple months for university education as an EE. She will get MS also. I hope my kidney holds out long enough to see that day for her. She will now have a good life and future and she will help her poor family also. Especially, her sister and young brother.
The girls are all just girl friends she has known a long time. Also, so talented and so beautiful inside and out. Sensitive, loving and smart. So many people are poor in the world and have to live boring dreadful lives because they are locked in bad conditions. They live in quiet desperation. You can make a difference.
Anyone wishing to go to Nepal should contact me and I will give you info on her father who is a guide.

Hi Richard,
Listen to your doctor and you'll make it. You really need to see how all your good work turns out.

Organic Nettle Leaf | Australia | The Source Bulk Foods
Hi Richard.
Since your mention of your kidney issue I looked for and found this stuff at a local whole/organic foods store.
I now throw a level teaspoon in with organic black tea leaves when making a brew in a plunger coffee maker.
Tastes good, and I reckon it has done me distinct good already in the past two weeks.

Yes ! Nettle ! I take 2 caps/morning and 2 caps/evening

Richard is in the right fiscal and geographic area to get
a new kidney ( should he choose ) .

It's really not that difficult to make a system that loads the right coefficients when the sample rate changes. It can usually happen in milliseconds. No need for sample rate conversion. Yes, need for good system and software design. I know its possible, we did it in a headphone.
Yes, I have done it before as well, I was just responding to the suggestion of resampling your entire library offline. It's definitely unnecessary in a system where the master clock is local and there is only one source.
Stinging Nettle is another stimulant. I suggest some caution. Pick whatever stimulants you like, Richard, but don't use all of them in a day. 2-3 of anything of them max. The only reason to try to stimulate more than that, is if you literally stop peeing.
Agreed. Two cups or avg less of tea per day each containing conservative amount of Nettle leaves (level teaspoon) four maybe five days per week for now is ample in my recent experience.....additional glasses of pure water are mandatory. In my recent experience this kick starts getting junk out of kidney/liver system and generally....there may be temporary adverse reactions. There is much cut/paste 'info' and claims on the net, only some is sensible it seems....some interesting old wisdom though. Like any such 'herbal', caution and time are involved, and be prepared to take intermittently.

Since I take other meds morning and night , I just add a couple of these :
Amazon.com: Nature's Way Nettle Leaf; 435 mg per serving; TRU-ID Certified; Non-GMO Project; Vegetarian; 100 Vegetarian Capsules: Health & Personal Care
Way more expedient than tea et. al.

Richard, I wish that I had something to contribute on curing your kidney problem, but I don't, unfortunately. All I can do is wish you well, and to read what others recommend. I personally appreciate any unorthodox approaches as much as the doctors approved ones. I too have found that some additions to diet can make a big difference with various chronic problems.
