| Received my Wadia i170 transport today. Oxia - I believe I can easily hear jitter in the 300psec range and so can you, depending on the spectra. (This is very difficult to measure accurately BTW). Here's why:I had a mod for the AE some time ago, including power supply improvements, new ... | |
| Received my Wadia i170 transport today. Dazzdax - As a matter of fact, I am currently selling OEM USB interface modules to several companies, including Ultra-Fi (the iRoc DAC). The new version iRoc will debut at RMAF in Oct. Larry of Ultra-FI and I are tentatively talking about a collab... | |
| Received my Wadia i170 transport today. Chris - a good transport will crush a stock iTransport. It uses the PCM270X part from TI to generate the S/PDIF output and reportedly has high jitter. This is not surprising since the AirPort Express uses the same part and has high jitter as well.... | |
| Received my Wadia i170 transport today. Why spend a lot of money modding the iTransport? It is a perfectly good mechnism for delivering the data intact, just like the AirPort Express, Squeezebox, Sonos or Duet are. The money spent on mods is wasted as soon as the next best device comes ... | |
| Any insight with the Berkeley Alpha DAC ..?? Drubin - I dont like to comment on the performance of other companies products on the forums, so I will send you an email.The Bryston DAC unfortunately uses one of the lesser TI chips, not one of the good ones. However, I am actually in talks with... | |
| Any insight with the Berkeley Alpha DAC ..?? Drubin - as for devices that use the audio stack in the computer, they are all the same in theory. However, the implementations and protocols used make some devices superior to others. PCI cards are the worst because they rely on too much of the c... | |
| Any insight with the Berkeley Alpha DAC ..?? Dougmc wrote:"As I understand it, quality computer audio systems bypass the sound card for conversion to SPDIF (and therefore for conversion to analog too) by taking the digital feed from the hard drive outside the computer. If this is so, why is ... | |
| Sending music to DAC wireless vs wired Rbstehno - you obviously did not read the reviews that I cited. The Spoiler is not only the best USB DAC, but the best DAC that the reviewer has auditioned. He has heard a LOT of high-end DAC's too, you name it.Steve N. | |
| the ultimate set up 1. how powerful must my PC be?If you are doing USB or Firewire, then more Ghz is better and bigger RAM. If you are doing networked, ala Squeezebox, Sonos, Duet, then it does not matter.2. what ripping software should I use?EAC for PC, iTunes for M... | |
| PowerBook G4 + Apple Express + iTunes +? to analog Your new proposed setup will work fine.Apple-lossess is fine too, although there are some CODEC artifacts, so It's not perfect. It is the best thing to do with Mac. You could also look at AIFF.Steve N.Empirical Audio | |
| Sending music to DAC wireless vs wired Rbstehno wrote: "the best external dacs do not use usb and the reviews of the dacs with usb have not been favorable."Not true at all. The review of the Benchmark DAC-1 USB, the Wavelength Cosecant and the Empirical Audio Spoiler USB DAC's were def... | |
| PowerBook G4 + Apple Express + iTunes +? to analog Syncrasy - why do you need the AE?Networked audio, particularly if you are only doing 44.1kHz sample-rate will be more trouble-free than USB. I would only do USB if you must have 24/96 capability. USB tends to hog system resources. It can work gre... | |
| PowerBook G4 + Apple Express + iTunes +? to analog Syncrasy - the connections would be:Powerbook -> WiFi -> AE -> Toslink -> Reclocker -> S/PDIF coax -> DAC -> analog -> Arcam ampSteve N. | |
| PowerBook G4 + Apple Express + iTunes +? to analog Syncrasy wrote:"Are you saying Airport Express's optical *and* analog outputs are jittery? Does AE jitter come into play if I'm using my AE simply for wireless transmission of data?"Yes, both are very jittery. The clock in the AE is a relatively h... | |
| Sending music to DAC wireless vs wired Jpod - you are missing the point. It's not that wireless is better than wired. The point is that networked, packetized data is superior to USB protocol for music streaming. The reason that networked (ie; ethernet), both wired and wireless is bette... |
