Turn it on

Looking for entry level DAC and wanna choose between these two, I can't find a way to compare them or try them, wish some audiophiles and friends can help me here and give me some advises, thank you very much

Hi, may I ask if anyone try the iDac and v90 before? Their price range is pretty similar, please give me some tips or advises on their sound quality if you have listened or compared these two product, thank you very much!

Thank you very much haujobb! Very happy to hear that your Wadia is fine and healthy, I have more confidence to step forward to the Wadia transport now after read your sharing. If I buy a transport, I need to pay extra but have a freedom to select any DAC; If I use USB cable, the DAC are limited; That's a very hard decision to make ^^" May I ask what is PSU you mentioned above? Thank again

Thank you very much for your advise! I'm searching for DAC past few days and found that choices are very limited for iPhone and iPad, mostly they are so called portable DAC... I'm still thinking about it. Would like to ask a question please forgive my naive, you mentioned "You are limited to the DAC as purchased unless (like the Nano DSD) there is an SPDIF output.", I don't quit understand this point as I only know to connect RCA from DAC to Amp, may I ask why would I need a S/PDIF output from a DAC and how important it is? P.S.: I haven't get any DAC yet but bought a iUSB Power! This product is really interesting

Thank you very much thrand1 and Eloise! I'm very surprised and never know that there is a built-in-DAC inside the lighting connector as it's so tiny! So I have 3 options now: A) iDevice --> dock/transport (Wadia/CA/drDAC, etc) --> S/PDIF Cable (Coax/Toslink) --> External DAC --> Amp B) iDevice + Camera Connection Kit/Computer --> USB Cable --> DAC (such as Concero) --> Amp C) iDevice/Computer --> Wifi/Airplay --> Apple TV+External DAC / airDAC --> Amp I'm quit hesitate and don't know how to choose May I ask: 1 - Is there any sonic different on data transfer between S/PDIF Cable and USB Cable? 2 - Is there any limitation or big concern on using Airplay to transfer data? I mean compare to option A & B~~ 3 - Should I use Coaxial Cable rather than Toslink Cable? Thanks a lot!

Hi I'm looking for a good transport for iPhone/iPad that doesn't have a internal DAC, any recommendation on Wadia 171i and Cambridge iD100? Are they both work great? I know Wadia is discontinued, is it still working with todays iOS 7? (I don't need to charge the battery and control the volume via the transport, just deliver data bypass i devices internal DAC is fine) Seeking for advices on Coaxial cable (from transport to DAC), and digital to audio cable as well, any recommendation? Thank you very much!
