Mabe I didn't understand your answer above - it may have been referring to something else. Thanks, bill I think Sean meant that because the Transporter utilises ultra low noise circuitry and super-regulators, the advantage might be lost introducing a converter at the amplifier end which was not similarly low-noise. -- Fifer Fifer's Profile: http://forums.slimdevices.com/member.php?userid=639 View this thread: http://forums.slimdevices.com/showthread.php?t=28111 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Depending on the devices at each end, very long! 100foot plus is fine with good quality cable, connectors and most important is the design of the devices at each end. Sound reinforcement snake cables can be hundreds of feet long connecting very high end mics and mixing boards with high noise rejection. Proaudio sound reinforcement websites can give you a more scientific answer. I would not worry about 50 feet though. I have several 50 foot runs and total silence when recording in the house and my recording equipment is not SOTA by far. Consider using balanced headphones. I saw this ad in Stereophile this month. http://www.headphone.com/guide/by-headphone-type/balanced-type/ They can modify certain popular headphones into balanced drive too, with cable length listed up to 20 feet, (mod=$400) but you might be able to get longer. Then you could use internal volume control from Transporter? You could also use a pro audio 2 channel mic preamp with headphone output: http://www.presonus.com/mp20.html but might be overkill and not sure about the headphone amp which is not an important feature on this box. Might be some other pro sound options if you look carefully, my quick search didn't find any gold nuggets. You are paying for the balanced amplifier stage which you will not use at all! Or, why not build your own balanced headohone amp, good sound @much less $! Great designs here, with PCBs: http://sound.westhost.com/projects-1a.htm http://sound.westhost.com/project51.htm http://sound.westhost.com/project87.htm I hope you're enjoying the new Transporter. I'm hoping Santa will bring me one.

I'm just planning ahead. Thanks for the links. My current headphone amp was a DIY kit which had options for either a balanced input module or to be converted into a full balanced amp for balanced headphones (which I could do with my Sennheiser HD650s). Unfortunately, the company producing the amp kit is no longer in business. I'll have a look at the designs in your links. -- Fifer Fifer's Profile: http://forums.slimdevices.com/member.php?userid=639 View this thread: http://forums.slimdevices.com/showthread.php?t=28111 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
[SlimDevices: Audiophiles] Re: Transporter balance outputs; some questions
I can't answer the balanced: how-long question or the converter question, but in terms of controlling the Transporter from the SB2, you don't need to sync. You can Felix Mueller's ShadowPlay plug-in: http://www.gwendesign.com/slimserver/dev_software.htm I'm using it now to control my Transporter from a couple of SB3s. Works great! -- gharris999 gharris999's Profile: http://forums.slimdevices.com/member.php?userid=115 View this thread: http://forums.slimdevices.com/showthread.php?t=28111 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
[SlimDevices: Audiophiles] Re: Transporter balance outputs; some questions
Notwithstanding the educational value of trying it, unless your headphone amp has balanced inputs, it's probably not a good idea to use the balanced outputs. You would need a _very_ low noise active balun circuit (super regs etc) in order to approach what's coming from transporters RCA outputs. However, if you're picking up a ton of noise due to having an unbalanced run, then maybe look into it. -- seanadams seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=28111 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
[SlimDevices: Audiophiles] Re: Transporter balance outputs; some questions
Thanks Sean and gharris. There was a balanced input option for my headphone amp but I'm not sure if it is still available (the amp was a low volume DIY kit and the designer is no longer in business). However, in case I can track one down, I'd still like to know what the maximum practical cable length is? -- Fifer Fifer's Profile: http://forums.slimdevices.com/member.php?userid=639 View this thread: http://forums.slimdevices.com/showthread.php?t=28111 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
