Edit: My mistake.  It's an S/PDIF *output*, not an input.



aww was excited for a minute there.

My bad.  But the JH-3A definitely has digital input, because Jerry's source was JP's Macbook Air into a Halide Bridge, to the 3A.

Oopsies I somehow skipped over that by accident. Thanks!

That is interesting indeed. Thank you it helped a lot!

No worries.  At least there's one more non i-ecosystem solution out there.

No problem.  Glad to be of service.

I have to agree with you on this.  I own a Zune HD myself.

The iPure has a digital connection to iPod but outputs spdif, so whatever chip is enabling this

has a spdif output, at minimum.  Therefore, if someone uses this chip in a portable dac/amp, they

could easily have a generic spdif input on the amp as well which would work with ipod devices and

non-ipod devices.  Another option would be an iPod to spdif cable between the ipod and dac/amp

for apple devices and a straight spdif for non apple sources.

 

I use the iPure (I first saw it at the northern NJ meet a few months ago) as an additional input

into my main home stereo system so that my daughter can play her ipod music through it with

a digital connection to a top flight DAC (I'm slowing weaning her from mp3 to uncompressed sound).

 

I would think non i-ecosystem folks would jump on this as well........or am I missing something?

 

Here are some links discussing the iPure i-20 for those of you not yet familiar with it.

http://www.head-fi.org/t/529956/pure-i-20-ipod-iphone-dock-as-a-dac

 

 

edit:  just in case i'm not making my point clearly, if designed internally with an spdif input that could be fed

by the chip in the ipure or any other spdif output, a portable dac/amp could support ipod and non-ipod devices.

however, let's be realistic here, without the ipod there is not enough volume to make this more than a small

niche product (yeah, i know, we audiophiles are all niche buyers) inside a niche market.

 

whatever chip the ipure i-20 uses enables digital input to dac/amps at a volume/cost that could not

be achieved without the ipod/apple capability.

 

 

added from head-fi thread above:

 

 

The i20 takes the USB stream from digital docking compatible iPod/Phones and re-assembles the USB data packets audio content into an i2S stream internally for it's high performance D/A converter. i20 also biphase mark encodes the i2S stream for transmission via buffered SPDIF on both optical and co-axial outputs.

As I understood from the conversation the digital SPDIF output streams are re-clocked by the DSP for accuracy but otherwise are untouched and are considered to be "bit-perfect" with the source material from the iPod/phone - therefore this data stream is not manipulated for volume control by the dock - the digital source is passed on "as-is" - a faithful replica of the source - hence the "Clearsound" moniker.

The D/A output (DAC - Analogue) has volume control for user convenience but note that performance is maximised if volume is set to full as digital volume scaling has some fidelity "cost" at lower levels.

^I think I am going to get one of these iPure docks plus a dock cable-extender so I can use either iPhone or iPad with my Benchmark.

 

To keep this on-topic, it will make a nice meet set-up so that anyone with an iDevice can use their music files to listen to my system.

 

Or, if I have the iPure, I can hopefully use my source/source material with another's set-up to audit...

no one says something about the new fostex????frown.gif

Is this any different than the Onkyo ND-s1?

AFAIK it does the same as the Onkyo, just much more cheaply. I went for the PURE and don't regret it - but then I never tried the other offerings e.g. Onkyo, Wadia, Cambridge Audio etc. I think you may find some direct comparisons in the PURE thread, address already posted.

post #567 of 678

The Onkyo ND-s1 only outputs digital.  Either optical or coaxial.  It has a usb connection but is only for synch use to a computer and not for sound output.  Onkyo released a new higher model recently but I dont know what it does differently.

post #568 of 678

Sorry for the OT, but can someone tell me if the SRM-009's are available now, and what is the best price they can be obtained for?

post #569 of 678

To clarify a few things on the Eddie Current stuff.

 

1-The BA was using generic Chinese 300Bs, not PX4KRs swapped in during the meet.  The driver was the 6F8G I thought it was but Raytheon, had Hytrons on the brain since I just bought some.

2-The Super7 was using the older prototype transformers not the new ones.  The new transformers were used in the 2A3.  They will be basically the same for the Super7 as in the 2A3.

3-The Electra is largely complete and has been undergoing further refinements so it's actually further along than I suspected.  He's just dialing it in and didn't feel it was ready for mass exposure.

4-Super 7 will be $1300 for preorders already made from the prior meets and any new orders by the end of the month and go up after.  Somewhere between $1600-$1800.

5-Electra is $2200.

6-EC might be making a 300B amp exclusively for Jaben.

I thought the EC BA was using Sophia PX 4 or KR PX 25s
