Hello fellow headfiers,


I was excited when I recently read @Hisoundfi's REVIEW of the Calyx PaT.  At the time, I was test driving the Cayin C5DAC and Shanling H3 portable DAC/Amps recently, so I was curious how the Calyx PaT would stack up against them and as a challenger to my DAPs.  The small size, battery-free operation, and built-in controls looked like great features not found in DAC/Amps I've tried.  

Out of curiosity, I reached out to Calyx to ask about touring some PaT DAC/Amps around the Head-Fi community.  They generously agreed to provide two PaT DAC/Amps for parallel U.S. & Canada tours.  Thanks, Calyx!

If anyone's interested in picking one up, here's where you can find them: LINK.

 
I'll be coordinating the U.S. leg of the tour, while [@=http://www.head-fi.org/u/411422/hakushondaimao]@hakushondaimao[/@] coordinates the Canadian end of things. Thanks for helping me out haku!


There's a dedicated PaT thread HERE.


CALYX'S PRODUCT DESCRIPTION

Is this a remote control for the their flagship model?


It sure looks like a remote control, and it kind of is in a way - a remote control that improves the sound quality on your smartphone :wink_face:

Serioudly though, he PaT is a portable DAC/Amp you hook up to your smartphone to improve sound quality. You can also hook it up to your computer, although I think it's really geared for portable use.

Out of the portable DAC/Amps I've seen, it's most similar to the Cozoy Astrapi and HRT dSP and Microstreamer, but the PaT has buttons that can skip / scan through songs and control volume, which seems pretty handy.

I've tried larger portable DAC/Amps with built-in batteries (Cayin C5DAC and Shanling H3$ before, but this will be the first of this smaller type that relies on the USB connect for power that I'll have tried.

Check out Hisoundfi's review and the dedicated PaT thread I linked to above to see what a few of your fellow Head-Fiers think. Maybe you'll want to sign up :L3000:

Hey hakushondaimao and nmatheis make sure you guys get the apple camera connection kits and include them in with the tour packages. If you don't reviewers will have no way to test them with their iPad or iPhone.

Might I suggest getting a kit for lightning connection and for the old iPhone (4 and lower)?

Welcome aboard @Cotnijoe!
 
Good suggestion @Hisoundfi.  I recently fell into that trap with the Cayin C5 DAC/Amp and Shanling H3 DAC/Amp.  It seems like the required iDevice cables don't come with any of these portable DAC/Amps.  I ran out to Best Buy and picked up Apple's Lightning CCK.  I know there are cheaper alternatives, but I've read about unauthorized 3rd-party CCK adapters not working after iOS updates...
 
Let's see some more people sign up now

Just got the PaT in. Snapped some quick pics with my iPhone. Here it is...

Simple packaging


Instruction sheet


Top & bottom of PaT (nice non-slip / cushioning material on the bottom)


Connections


Accessories


With my iPhone 5s (PaT is tiny!)


The ever-present challenge with DAC/Amps + iDevices - cable management (Please Apple, stop making us use that @$!*%# Camera Connection Kit!!!)


Eager to give it a spin later tonight :L3000:

Sweet! Wonder what colour the Canadian contingent will be playing with... (and when it'll get here).
 
Guess it's a Best Buy trip for me tomorrow in preparation!

Hmm, I might potentially be interested in this, though I'd probably test it more purely from a laptop.

Might potentially? Let's see some enthusiasm!

Nothing wrong with testing a DAC from a laptop, since a lot of Head-Fi'ers will be interested in that specific usage. I'll probably be doing the same.
