I2S, S/PDIF, Toslink connections
Cymbop - Actually you can stream USB output from SB Touch, but it requires a USB converter with Linux driver compatibility. The HiFace2 will work.If you wanted to reduce jitter from S/PDIF coax or Toslink, this can be done with a reclocker like th... 
Streaming via SONOS Bridge vs. iPhone
The Problem with Sonos is jitter. This will handicap it from the get-go. However, for both Sonos and iPhone, this jitter can be minimized using reclockers such as the Synchro-Mesh. The quality of the digital data from iPhone and Sonos will be iden... 
Pure Music or Amarra with iMac
Peter - Many computers have different USB ports on them. Some are USB2.0 compliant and others are not. Some are full-speed capable and others are not. Try another USB port. Also, make sure that the port is not disabled due to excess power use on t... 
NEED HELP WITH A QUESTION
The simplest way is to get a Sonos ZP-90 and a Synchro-Mesh to reduce the jitter. It is connected computer -> network -> Sonos -> Coax or toslink -> Synchro-Mesh -> coax -> Esoteric. You can drive it from most computers and other... 
I2S, S/PDIF, Toslink connections
Cymbop - It has Coax. The OR5 has BNC coax (with RCA adapter), AES/EBU, RJ-45 I2S and HDMI differential I2S. All active at once.The OR5 USB interface does not currently support Linux without a special driver. OR6 will be XMOS, so it will work. OR5... 
I2S, S/PDIF, Toslink connections
Mesch- the Empirical Audio Off-Ramp 5 outputs both differential HDMI I2S and single-ended RJ-45 I2S. it works with W4S DAC2, PS Audio PWD, Northstar, Stello, Empirical Audio, Perpetual Technologies, Buffalo and others.Steve N.Empirical Audio 
Pure Music or Amarra with iMac
Specifically I recommend version 4318/19 of Amarra. Of you own full Amarra, you can download this version. Not as stable as the latest, but better sounding IMO.Steve N.Empirical Audio 
I2S, S/PDIF, Toslink connections
Given that the system does not have significant ground-loop noise, the coax interface will outperform the Toslink, If you use a decent coax cable that is. The Optical conversions add jitter. If the system has a lot of ground-loop noise, the Toslin... 
A thought experiment
The D/A has jitter in it and the A/D adds more jitter. It would degrade the result. You can test this with various DSP devices for crossover, room correction and equalization.Much better idea to apply DSP in the digital domain and then just do D/A... 
Synchro-Mesh
Ozzy probably got one of the few SM's with a non-optimal output transformer. These transformers could be very good or not as good. These have been replaced with a different transformer in the new builds. Mods are available for older units to bring... 
Ipod Docking,DAC,Preamp,Headphone amp,remote
Your best SQ will be with a Pure i20 driving a good tube headphone amp. Pure has the remote. Tubes are the only way to listen to headphones.Steve N.Empirical Audio 
Best Dock , DAC
Mil - It is standard analog 2-2.5 VRMS, just like most DACs.The real question is what kind of drive does it have. Undoubtedly an op-amp output stage at fairly high output impedance. Not great for a TVC....Steve N.Empirical Audio 
Best Dock , DAC
Tm - the digital out sources from the iPod, but its through the special docking station that it is accessed. These stations usually have S/PDIF coax and Toslink outputs. There are 3-4 docking stations like this, including the Pure i20 and the Wadi... 
Can I Improve Sound--Macbook Pro as Music Server?
Simplest thing for you will be to get the "audio Optimization Guide" from iTunes iBooks for your Mac OS. Search on iTunes iBooks. This has step-by-step details on how to kill unnecessary applications.You can swap out the hard drive for a SSD by us... 
Which DAC has best headphone stage?
If you only listen to headphones, buy a Bottlehead SEX1.2 and build it. Put grey-plate tubes in it. Beats everything else I have heard. The only way to listen to headphones. Forget about DAC/headamp combos. The only one of these I would consider i...
