I was looking into getting the CLAS -db to pair with my ALO Audio "The International" but I'd like to get some opinions of the community as to some other highly regarded portable DACs.
Since your source is IPC, that means you should have eliminated well over 90% of the choices available.
Not that many companies went for that MFi certification by Apple. Basically you might end up with a dozen brands (or less) to boot.
Then you further limited your options to match the form factor of The International. The only thing remotely close to that would be VentureCraft GO-DAP DD SOCKET 1 at the moment
HRT iStreamer is bigger than what you want.
CEntrance HiFi M8 / Fostex HP-P1 / Sony PHA-1 are too large because they already have an amp included. Finally there are maybe a handful to choose from:
3 flavors of CLAS
1 more from VentureCraft
Thanks! I would also use it for my laptop a lot as well
