I have ordered my iDSD, in few days I'll be able to see how good is that baby:cool:
post #212 of 1712

Thanks for the quick responses from iFi staff... I did figure out that the RCA's are disconnected when the headphone jack is plugged in. No biggie. The battery circuit is interesting.... So, it sounds like, even if the DAC is turned on after it is attached to the computer the DAC and electronics draw from the battery. So no difference between turning the DAC on first or second, in terms of where it gets its power from. Just that the charging circuit is not operating if it is turned on first.

 

One other thing - I noticed that the digital volume control on JRiver MC19 does in fact work when set to internal, when redbook is being upsampled to DSD via DoP. I guess the volume control takes place before it gets converted to DSD. Is that right? The other thing I noticed is the volume control on the iDAC is a bit 'unstable' at the very low volume setting. It tends to 'break up a bit'. A small increase and all is well. With my Emotiva the volume level where the control stabilizes is a bit high for low background so I do a bit of digital attenuation on the front end. - Again - sound is awesome. The bass is quite good. Dont miss the sub.

Any more detailed info about headphone output power in different loads?

 

I think it's 130mW - 16 Ohm

       

                   80mW - 32 Ohm

 

Is this correct?

 

Any info with other loads ? 50 -120 -300 Ohm.

 

Thanks for all your replies you are giving!

@iFi audio 

 

any info for the above?

 

Thanks.

Hi

 

The lowest few steps of the Volume control are 4-6dB and the pot is arguably a bit fiddly in this position. 


Best add some fixed line level attenuators. Same as with Watcher. Have a chat with the dealer from whom you purchased your unit. We can but try to see what we can do. 

 

As for JRMC it is up to you to switch in or switch out the digital voloume control but we do our listening without the digital volume control on all playback software. You already know why!

 

Any questions, just ask.

re.output power iDSD... Maximum output is around 1.8V RMS into a line level out. Headphones a little less.

 

Power is calculated V^2 / R so 1.8V squared (3.24) divided by headphone resistance, hence for 50 Ohm 3.24/50 = 0.0648 or 64.8mW

Thanks - I will probably use the top several db for digital attenuation that I can control from my listening position. Still, very impressive sound quality for an under $200 DAC. Unheard of a year ago, and unmatched till date from what I can see.

@iFi audio

Can you please help me?

I have an iBasso DX50 and I´d like to connect that to the iDSD, but I don´t know which cable I have to use.
There is a P2-Coaxial cable that was included with the iBasso DX50, however that doesn´t seem to work.

The only way to use the iDSD was by connecting it over USB to my notebook.

I appreciate any help. Thanks!

No cable will work as iDSD only accept USB input, not SPDIF coax from DX50.

Some Balanced goodness.  dsd files from ipad3 to the HE500's.  Spectacular sound, I swear the guitarist is in the room with me, sitting on the opposite sofa!

post #221 of 1712

Ok I'll admit... I do hear a 'better' sound using the volume control on the iDSD with the JRiver control defeated. Its very subtle but with the iDSD its noticable. The iDSD is so SMOOTH. As a baby's ass. Any chaff is noticed - front and center. Pretty impressive amount of definition from a $185 DAC. Or any DAC for that matter.

post #222 of 1712

To confirm before I grab one, I just want to make sure the iDSD will work with my iPhone 4 with the appropriate camera connection kit.A pretty old model so just want to confirm.

not sure, but i would think that if the CCK works with the 4, it should work with the iDSD, as all it does is receive the appropriate usb signal.

 

the bigger problem is getting the appropriate software to work with the CCK/iDSD. the onkyo hf player, for example, is supported only for 4S and newer. but it might possibly work on the 4...not certain, though.

post #224 of 1712

Another welcome surprise.... The iDSD also seems to sound very good at good old PCM. I was starting to miss my sub, so I switched the DSP in JRiver back to play as 'native', and also tried it with an upsample to 24/192. I will say, the 16/44.1 sounds very good. Better than any other of my DAC's playing redbook. The 24/192 upsample did not produce a noticeable difference on first blush. Now I can run my secondary DAC for my subwoofer off of the RCA digital out. Nice strong signal from the Coax. What I am noticing about the redbook playback is that is has that same vocals as I noticed with the DSD upsample. Nice timber and tone, good clarity and nice decay. Again, I can listen INTO the music a bit more. A bit like vinyl.

Thanks. I am a bit confused though. With the iDSD, proper Windows driver and CCK kit not all audio would be sent to the iDSD? Would I not be able to use iDSD, or Spotify or other streaming program (TuneIn Radio for example) available on my iPhone?
