My HD558 is almost here, and I don't have any headphone Amp for it. The DAC will be my X-Fi Titanium HD, but the Headphone Out has a pretty high impedance, not adequate for the HD558 50Ohms headphone.
I almost bought an O2 headphone Amp, but it didn't fit my needs, I don't want portability, as soon as I read ODA was going to be released eventually, I decided to wait for it, since it will be the perfect match for my usage. Until that happens, and it can take a long time until ODA comes out, I'm looking maybe about getting a good and cheap Headphone Amp to do the Job.
The JDSLabs cMoyBB seems to be very good, and at a reasonable price I wonder if it's a good investment to use until I can get a definitive Amp.
What do you guys think?
