Holo Audio May DAC

Just read a very nice review of this in Stereophile this month and after doing some research it looks like this one could be a very nice option for me.  
It's made in China I think (or could be Taiwan?, and yes, I am very well aware that these are two very different countries. ;)), and employs a direct to consumer model to keep the price as low as possible.  This does not worry me after purchasing a Jay's Audio transport from Vinshine Audio and having zero issues.  

Just curious if anyone here has heard one or purchased?  I'm very intrigued.  I know the Denafrips Terminator is another highly regarded DAC with a similar ordering model, but costs a couple grand more than this one.  Considering that one as well.


I also run a Holo May DAC right out from the USB on my iMac, into an Auris Nirvana headphone amp. Before I did anything with the DAC, I just turned it on and left it that way for 3 weeks. These things require a LOT of burn-in, or so I'm told. But it sounds great and I've had no problems. And yes, I believe you are correct, @yakbob about the Audio Midi Setup... 


There are some having this issue using JCAT usb boards at high sampling rates, looks to be something with the chip used on those JACT boards. Appears to have been addressed via firmware from holo. Also I "think" there was mention about the midi setup used on macs - See this for ref


Thanks to you both for your replies.

@redlenses03 , your link to head-fi was helpful. It appears Macs and May dacs have had incompatibility issues. I wish i knew that before purchase.

Kitsune or should i say Magna hifi appear to be rolling out firmware updates for screeching sounds on Windows machines, but it doesn't really help the mac users since device drivers aren't required in the first place. If a firmware update to the May was availble, I'd certainly give it a try.

I have a support ticket into Kitsune, but wonder if I'm going have to unload this unit or try some usb to coax or optical converter,, which will defeat the purpose of having the "upgraded" Titanis USB on the level 2. 

If i can find a solution, Ill report back for any other mac users out there.





I'm not sure what you mean by "however is forced by the May at 32-bit"

If you are using the upsampling in the May (that could be forcing it) otherwise nothing in the May is forcing the bit rate (to my knowledge), definitely turn that off and set May to NOS.  Then you can play native rates or upsample via an external program like HQP etc..  Of course all IMHO


I mean that when in the iMac's Midi Audio setup panel, the Holo May is seen by the mac, and the format can be changed (44.1 khz, etc.) But the integer is not selectable and set at 2-channel 32-bit integer. It appears the 32-bit integer is being set by the May.

The clock source for the macs built in output is set to "default".

The clock source for the May is set to "device" and cannot be changed, which leads me to believe the May is telling the Mac it's handling clock duties.
