I have read in several posts that the idsd has quite a powerful preamp. Can someone please tell me if it'll be able to drive 30K input of my amps, does it have 6V RMS?

 
Hi,
 
The micro iDSD can drive 10k and above. So 30k should be fine. Also, it can reach 5V (and more) in Turbo mode so your query for 6V should be still leave enough in reserve. Obviously set to Turbo which gives the most drive as it can actually reach up to 10v but we stated a more conservative figure.

Specs are just a guide. Use our Support Ticket System and one of the techies will give you a more informative/accurate reply.
 
Cheers.

What kind of power amp needs 6V input?

Most require in the range 0.5 to 1V.

Yeah, the cheapest I can get it is for $600 from eBay, but that's still a bit too much
Are there any good alternatives? I will be using an IEM (Aurisonics Harmony)


Remember that if buying from an EU outlet, the price quoted will include VAT which is usually around 20%.

As a non-EU purchaser, you do not need to pay EU VAT.

Get the supplier on the phone and ask for an ex-VAT export price.

You may still have to pay import or sales taxes on entry to Israel.

So is something like using a Pure I-20 dock the best option for using an Ipod Classic (6th/7th gen) with the micro, or is there another connection that doesnt required an iPod dock?


I realize that the Micro doesn't officially support extraction of a digital signal from the iPod Classic, but what's the best 'unofficial' option?  Using the Micro as a DAC to the Liquid Carbon amp.  Is something like the Pure I-20 the best option to bypass the Ipod DAC, or would a simple line out from the Ipod's 30 pin to the Micro's 3.5mm input work just as well?  http://www.amazon.com/FiiO-L-Shaped-Line-Cable-iPhone/dp/B005N6ZAT2


The Pure I-20 will not extract a digital output from the iPod Classic.

Only iPod Touch had digital output capability.

That is not correct. The I-20 is licensed by Apple and has the hardware chip that allows it to negotiate a connection to the iPod Classic digital out. You can also connect to the line out of the iPod Classic, which does not require a license. See the I-20 user manual for details.

The Pure page I visited did not have that level of detail.

The retail sites I visited suggested that only the iPad and iPod Touch are compatible.

However, more digging on the Pure I-20 has turned up this:



So it would seem some later models of the Classic from 2007 and 2009 are in fact supported.

Thank you mbusby.

Thank you for your prompt reply, I have opened a ticket with my query to the technical dept as per your suggestion.

I can't help but notice the professionalism and speed at which IFI/AMR responds and caters to queries, here on this forum as well as their company site, I'm very very impressed.

Yeah, this is true. I haven't found any audio company with this type of excellent customer service. They know what they're doing, that's for sure.

I have the Pass Labs XA 100.5 monoblocks, please check the link for specs....

https://passlabs.com/products/amplifiers/point-5/xa100.5


The "Full XA.5 Series Specs" PDF says that the XA100.5 requires 1.41V for full output.

I have iFi Micro iDSD (was originally coming with 4.06 firmware) for a week or so... sound-wise I like them a lot, thanks...

I have problem with USB-3 connections (PC, 2014 production, Intel i7, 16GB RAM, MSI gaming-motherboard)
I can't get rid of random weaker clicks and louder cracks during listening of music. It was more annoying with original 4.06 firmware, after updating to latest v5 firmware, there is less cliks/cracks, but still all time there (no 'clean' signal over 15 sec is possible?!).

But everything is OK with USB-2 connection...
 
Nothing changes if trying different setups on iDSD itself.
 
Software in user is Foobar200 and changing any changeable parameters there did not helped to get rid of clicks at all
 
If I stick with USB-2 connection only, am I missing something or not??
 
Thank You for possible solutions-suggestions...
 
EDIT/added: Important, upper-mentioned problem was some mysterious 'week ago' problem, just now I switched back from USB-2 to USB-3 connection and for some mysterious reason (iDSD burn-in?) now there is only minor (not loud) clicks, about 1 during one minute with USB-3 connection. I did not changed anything during the week (nor with PC, nor with iDSD device, nor with Foobar2000 setup). HMM! Maye soon are all USB-3 related clicks gone?

In the end I decided to take quite a sharp turn and buy a ZMF Blackwood and a Vali 2+Modi 2 Uber
Thank you for your help though!

Thanks very much.  So with I-20, can I bypass the Ipod DAC and the I-20 DAC and use the Micro's DAC?
 
Whereas something like this would not bypass the iPod DAC? http://www.amazon.com/FiiO-20-Inch-Line-Cable-iPhone/dp/B005DK08X6/ref=cm_cr_pr_product_top?ie=UTF8

Most definitely won't
