Recently I upgraded to a pair of Grado's Prestige Series 325e's and am using the Cambridge Audio DacMagic 100 with JRiver MC 20 on OSX 10.11.2 [El Capitan latest build - no luck with Integer Mode). I am looking to purchase an AudioQuest Cinnamon USB A to B interconnect 1.5meters. My DacMagic 100 has 2 S/PDIF outputs as well as a Toslink. I used a generic Toslink cable that is well over 5ft long and connected it to my Mac Pro but received a large amount of interference. My DAC will only output in 176.4 using Toslink and I prefer 2x or 4x upsampling instead of oversampling. So any good recommendations on a Toslink cable similar in quality/price range to the AudioQuest Cinnamon series would be greatly appreciated.
I am looking at several dedicated headphone amplifier for my Grado's. Specifically, Creek Audio OBH-11 Headphone Amplifier ($275) or MusicHall's ph25.2 ($399). My general rule of thumb is to spend twice as much on a DAC and headphone amp as your headphones, but I think there are plenty of people on this forum that know more than me, so please, I am very open to suggestions. My main goal is always to learn so please comment and help me out! Thanks in advance.
