@iFi audio is there any harm in leaving Pro iDSD on all the time when not listening to music? I never use tube option, so no impact to tube life.

There's no harm in having Pro iDSD engaged for days, but it's good to turn off audio products not in use in general, especially those which generate heat

Yes you are correct, DSD1024 currently in test. That is with the USB cable included in the package and the USB port of my X299 motherboard, which is FAR from beeing optimised... Waiting for a Roon endpoint firmware upgrade *whoop*

I input hqplayer upsampled dsd256 to ifi pro idsd and further upsampled that to dsd1024 using GTO. Just about every comment I read that's not a good idea, but I like the result.

HQplayer's upsampling algorithm is solid. Actually, we got feedback from others that they like the effect of data converted there to DSD prior to sending in out to Pro iCAN for further hardware upsampling up to DSD1024.

I had a discussion with someone yesterday about something I had never considered before, ensuring that the power supply to my equipment is as clean as it can be. This led me to look at the IFI Power Elite, and wondered if at £300 it is likely to be a worthwhile investment. I am using the IDSD Pro as my DAC, and I amp my headphones using the ICAN. Presumeably, I only need the one Elite for the ICAN? Also given the below, which voltage would I need to buy (5,12,15 or 24)? Any assistance appreciated!

Pro idsd is 15vdc.I beleive ican is the same, should be marked as such on input. LPSU can be very expensive, I use one but noat the ifi one. I don't have the ican, but if you are looking to have lpsu for both, have a look at the hdplex 300w with 2 outputs voltage configurable.

Yes, power quality in general is considered as very important and digital devices are components that benefit from it the most. That said, Pro iCAN needs a 15V/4A DC power supply and we have iPower Elite that matches these specs. As for this PSU, we got a lot of feedback how much of an upgrade it is for our non-Signature Pro range; Pro iDSD and Pro iCAN. If you're interested in pushing your Pro iDSD's performance further, iPower Elite is a very nice way to do that.

I’ve had the OG idsd for nearly 3 years and leave it on in SS permanently no issue

Yep, it's not an issue, but we always say that it's a good practice to turn off audio devices not in use

Ckuple of questions on upsampling dsd64 to dsd1024. Does the upsample process convert to pcm first. Also if I feed the pro idsd with dsd512, is it a pure direct through or does the filter e. g. GTO come into play.

As far as I know it’s straight conversion , as for feeding direct it won’t use any digital filter unless you then engage the 1024 DSD conversion on said “fed” 512 on doing that you can engage any of the filters on the IDSD

Pro iDSD's FPGA upconversion from DSD64 to any other DSD is a straightforward process that doesn't involve PCM and our GTO filter applies only to PCM.

Well, few months are now gone, and I can't say I'm sad with the iDsd pro signature. But I really, really am looking forward to a firmware upgrade to roon endpoint, it is really for me the key element missing to what is a real jewel.
I have had nothing but good times with my TH900MK2 with the hybrid Noir cable and the 4.5mm input

Um, yeah...firmware/software upgrades are not iFi's strong point. You might be waiting for a while.

Excellent cans (they look gorgeous!) and cable! Matt is solid!

That's a fair comment and we take them into account, thanks!

I do not have doubts that you guys are working on a way to make the Idsd pro and pro signature roon ready, they are excellent gear, and with the price we have paid, they deserve to fully be that "jack of all trades" that they really are
