A few piccies...
An externally hosted image should be here but it was not working when we last tested it.

Yes we have. 🙂
We measured (with AP) -118db THD+N and about 129db DNR in stereo mode.
Cheers!

Cheers Merlin.
I am running one transformer/rail... + little one for +5V VD supply.
At least in my limited understanding of electronics, I am 🙂

Check your PMs. Don't want to step on toes 😉

In the pics seems that you are using toroids with two secondaries, so if you are regulating 7 rails, 6 per IVY III & 1 per BII you need 7 Tx.
Use only one Tx for each rail= 7 Tx, you can use also that's you have on hand simply paralleling to get more power & after only you need to add 4 Tx more same voltages & current like you are now feeding the IVY III & voilla, this setup it's to use the Tx that you have, but best will be only 1 Tx with only one secondary per each rail, do you understand me now?
Yes!
Cheers for the explanation.
I might add another Tx, and run the Ballsie off that, and one channel of the IVY3 from each of the others. Mate said he preferred that setup with his B32S.
For now though, I'm just enjoying 😀
The budget is well and truly spent 😉

Dear Russ:
thank you for the measurements - there is nothing like hard facts 😉

Now if someone could give a brief explanation as to why these are good and how they compare to anything else, my curiosity would be satisfied. 🙂
Failing that, a link to somewhere that explains it would also be much appreciated.
PS 7 transformers! That would be one heavy DAC! You'd need a real Buffalo to carry it anywhere.
How do you read these charts?
I suppose for the THD chart, the highest peak (at ~25K) gives you the -118 db THD number
The DNR, the highest peak is also ~ 25K and that is at ~143 db?
With the harmonics so low, I do not think there is any DAC+IVconverter+filter that beats this measurement. 3rd is at -122 dB and 2nd is even lower.
Still, it does not say how it sounds.
How THD+N is calculated from such a graph can be read about on Wikipedia. It is easy but tedious.

That cannot be shown on a chart, of course.
If it didn't sound good, we would not sell it (since we use all this stuff primarily for ourselves). 🙂
I just realized that I had not accounted for Daylight Savings when setting up the timer on the web page. It has just become one hour closer to sale time! (Timer is accurate now.)

Guys, I think we set some sort of record selling these things out. It was only a few minutes before they were all gone.
My apologies to those who have waited and are still waiting. My congratulations to the lucky few. 🙂
Good news though, we will be opening up orders again in much shorter rolling intervals.
Cheers!
Russ

Listen guys Brian and I are a two man crew. We are making these things as fast as we can, and we are finding ways to make them faster.
Remember most of the parts we use are expensive, and the clocks are custom. We test all the units ourselves. Brian has an incredible amount of work with assembly/testing/shipping.There simply is no fast way to make these things with our current resources, but we are expanding those resources every day.

There appears to have been a few stale orders, so a few more are available.
We make as many available as we can at a time. There will be more available in two weeks, then again two weeks after that, and so on. Regular production is now in full swing, but still comes in batches.
