Oh audio porn. Big Mouthed horny speakers and Curved line arrays!!! I’ll be damned the dam is flowing. 
Now just missing some of the tumultuous tears.

I just received a text from DHL…it looks like my May KTE will be here on Wednesday!
Edit: I ordered the May KTE on November 18th.

Due to space limitations, it’s still necessary for me to stack my May KTE power supply and DAC. I am wondering if anyone has had any benefit in using Isoacoustics or other anti-vibration products in their stack?

Clarification question: Are you stacking just the DAC and it’s power supply or with other components as well?
I am just stacking the DAC and power supply. All of my other components are on separate shelves.
I suggest placing 4 IsoAcoustic Bronze footers between the power supply and the DAC. It will give you great isolation and some distance for airflow between the units.

I’d give a counterpoint. The feet on the product are sufficient. If the May is similar to the Spring, there aren’t ventilation openings to be concerned with. The cases were made of such heavy gauge aluminum they provide their own vibration dampening in addition to units feet.
Microscopic tweaks I just type will be in audible at best until your past 500 hour break in period.
Maybe….I do agree for any critical listening or making tweeks I would wait until after 500 hours but the reasons I would add the Orea footers is that I believe the footers on the May as well as the Spring DACs are aluminum. That would then most likely drain the vibrations from the DAC to the power supply.
As far as not having ventilation openings I would think that the May’s dual power supplies would run a bit hot and transfer some of the heat to the DAC. As always IMHO and YMMV.
Actually the power supply unit runs cool it is the DAC that gets hot. I would just use the Iso standard pucks which are about half the cost of the Orea footers and work just fine. You are looking for separation and the Holo footers while better than many are not tall enough. Herbie’s also make things that will work like the Big Tall Tenderfeet which will give you an inch clearance between the two pieces.

My Spring 3 KTE has been on and running for nearly 5 days and the aluminum is still cool to the touch.
Holo has also built integrated anti-vibration feet in a clever manner. Each foot has 5 semi-circle rubber dots. Its actually the best factory anti-vibration feet I’ve seen on hifi gear. Instead of resting on fists it’s resting on finger tips. The Holo guys thought of everything.

Thanks guy’s. I just assumed that with the dual power supplies the unit would give off some heat. I stand corrected. 
They do but it is the DAC unit. I have my power supply on a spiked butcher block beside the rack and the DAC unit gets the shelf by itself.

My May KTE showed up today and is now on and playing songs through both the PCM resistor ladder and through the DSD resistor setup. Let the burn in begin…
I ordered the May KTE on November 18th.

Congrats, looks like they’re getting a little quicker on delivery.

The May KTE now has 20 hours of break in. I decided to listen to the DCC Gold unreleased version of 10cc’s “The Original Soundtrack” upsampled by HQPlayer to 705.6kHz with the poly-sinc-ext2 filter and LNS15 dither.
All I can say is “Wow!!”

Jussi says the newest Holo’s do PCM best at ~1536kHz
Can you do that or is your streamer limited to 768kHz?
I’d be streaming to the May at double what I am now if the ultraRendu I use as an NAA supported it….
That’s why I asked “or is your streamer limited to 768kHz?”
Objectively going to PCM ~1536kHz is better (Jussi has shown).
And actually objectively little difference at that PCM rate with DSD256 , even though he subjectively prefers the latter.
He recommends the UpBoard Gateway as NAA (little 5Vdc Intel Atom based fanless unit) running NAA OS, to do PCM1.5MHz’
You should get one of those and try

I installed the generation 2.1 usb card in my KTE May last week.
I can’t confirm that the ultraRendu can do 1.4/1.5 MHz PCM, but I am running 1.4/1.5 MHz PCM with my Sig Rendu SE optical.
If you are using an EtherREGEN before the ultraRendu, 705.6/768 KHz PCM will be your max rate, which BTW sounds very good.
When I had an ultraRendu, the EtherREGEN was the way to go and you can take it up a big notch if you add an AfterDark 10MHz clock.
I would order an UpBoard but they are on back order and use a 5v DC power supply. I don’t want invest is another LPS….why can’t they use 5v to 9v supply?
