Hello, sounds like an earth loop. Removing an earth connection on DAC or source might work.   On my Yamamoto I recognized that some RCA plugs do not connect fine. Try some other RCA cable.....   Kind Regards

Quote: Go get a longer runtime on the battery. (Seems to be bad for some camera users, who want to upload their photos to the ipad, too. Maybe it is a bug and will be changed in the next update of the IOS????)

I just read that Apple reduced the power limit for USB devices from 100mA to 20mA in IOS 4.2.1. Several USB hubs, incl. T3hub, seem to be a workaround.   Cheers

iBasso DB1 Boomslang does not work connected directly but does work with T3hub for me.   Cheers

Quote: For me the question is more theoretical. In real I prefer at home the chain - macbook>DAC>......   Never tried an active hub in an audio setup .... size and weight seems not to be an advantage of an active hub (+ power supply).

You need no power. :)

Quote: Might work with factory reset. (?) (But the iPad feels faster with 4.2.1 and Keynote 1.3 seems to have got some new features when using the pad as a presenter.)

My D10 connected directly doesn't work any more BUT my little workaround (might work for ALL portable DACs)   I connected a Dr.Bott T3Hub (I have the old USB1.0 version) between the connection kit and the DAC and now D10 and the Sigtone h1 work...

I updated to 4.2.1. So far I can tell that the HA Info NG Coax USB interface and the PopPulse PCM 1796 DAC works fine.   With the Sigtone / Shek h1 I get the error message - no work - (Maybe I have to load the battery of the Shek completely before connecting because it wants to...

Quote: Hello, why not use some adapters, i.e cinch/RCA to cinch/RCA + some angled adapters? I use something like this to connect an USB/SPIF interface to a DAC. (A little adapter chain: RCA plug - BNC socket, BNC plug - BNC plug, BNC angled, BNC - RCA, I used BNC because I thought...

I can not recognize any imbalance on the Toucan (neither on the D10) in the range from zero to 9 o'clock......

Thanks for the work, John.

For those looking for an USB-SPDIF interface, this one works fine with the iPad and any DAC with coax digital in.   http://www.ha-info.com/english/ngcoax.htm

Quote: Thank you. Marco from m2tech confirmed: hiFace can't operate from the USB of an iPad as there are no drivers for its OS.  

I tested some DACs with the camera connection kit. iBasso D10 - works flawlessly (charge off) Sigtone h1 - without any trouble PopPulse PCM 1796 DAC - first an error message, but after reconnection works fine USB monica NOS DAC - no problems   + tried connecting the PopPulse DAC...

Boomslang offer is online on iBasso site http://www.ibasso.com/en/products/show.asp?ID=61  

Thanks Chris and grokit for the information about the HiFace....

I do not know whether someone has posted this link. It is leading to the german press release for the T5p. At the bottom of the page there are the technical informations and some pictures. Release date: September 2010...

Are there any experiences in using a M2tech HiFace USB stick?

HiFlight/Ron, thanks for the review/comparison. (I also see the extented dynamics, cleaner sound, firmer bass when going from SE to balanced on the PB1.)

Hello. Seems to be that some have ordered the DAC. What's your experience with it? Does anyone know how it compares to the North Star 192 DAC(s)?   Thanks - and a nice summer (winter for the southern hemisphere)

Quote: Thanks for the informations. Nice setup. Heavy portable rig ..... :) (I think I will wait for the second or third generation iPad. It may become lighter and faster ....) Would be interested how the t5p compares to the T1. Does it have the same sound signature, resolution...

For those interested in adapter solutions. I changed the original plug of the T1 to a five pin Neutrik XLR plug. The adapter connects the iBasso to a five pin XLR cable socket using Mogami cable (2893 Mini Quad), which is thinner than the Beyerdynamic/Sommer cable Peacock MK II. A second...
