Well, hello my old thread, how's tricks?
It just so happens I've been enjoying my CCA more than ever but not in a way I'd ever expected. Sadly, it's got nothing to with surround music, but even so, I thought it's worth sharing all the same. In a nutshell, the CCA is a phenomenal headphone amp and DAC all in one - even when it's being powered by the battery in my phone via an on-the-go (OTG) cable!
I never had a phone that had OTG capabilities when I bought my CCA back in 2016, but damn, these wee gadgets can run off the power of a phone (or tablet) that supports OTG i.e. a USB connection with suped-up functionality. This means the CCA has the potential to become a portable device. And it just so happens it has incredible potential in that regard as it can drive my Sennheiser HD650 headphones with aplomb and then some. Seriously, the puck can drive them like a monster truck can drive like, er, a monster truck!
The soundstage is wider and seems deeper, too than any previous headphone combo I've had. Plus everything is crystal clear and snappy as hell and with plenty of bass to boot. I can't believe I'm typing all this but the CCA is one helluva headphone amp.
As for playback, I've got FLAC files stored on a USB drive connected to my Nvidia Shield TV, and I use PLEX (I've got PLEX server enabled on my Shield TV and PLEX app installed on my phone) to cast those files to my CCA, which then drives my HD650s. I reckon I can listen to about five albums or so before the battery in my phones dies due to the extra demand placed upon it by the CCA. If I want to listen for longer, I can just plug the CCA into a mains socket of my choosing and then settle in for an enjoyable listening session.
While this portable mode of listening is only portable within my house - specifically, within reach of my wifi router - it might well be I can use my phone to transmit a wifi hot-spot signal that would allow me to use the CCA anywhere as long as my phone has enough battery. I obviously wouldn't use my HD650s out and about, as it were, as they're not suited to outdoor use, but in principle, the idea might have legs.
Suffice to say, if you've got a CCA lying around the house yourself and you've ripped your music files, it's worth exploring just how good the CCA is as headphone amp/DAC. And all for the price of a bag of chips (if you live in Kensington, London)
