Contact “bluesaint” on this thread. He set me up with two pairs of tubes that work and sound great. One is a different version of the tubes supplied by iFi and the others were a pair of the WE396a’s. Best of luck.

heh thx for the shoutout. I actually have a premium set of JW variant from early 1950's of the WE396a that I guarantee works with iDSD/iCAN PRO as I had them briefly in my own setup before selling the unit. Anyone interested can ping me.

The Pro iDSD layout does not make it easy to swap tubes. Very tight fit and have to be careful pushing the tube into the slot swith not a lot of base support. If they don't work, it is possible that you did not get it in properly. I would try again.
Yeah, at first two try it was very hard to take out GE5670 and put WE396A, i must wiggle tube around to take it out and put in. Itt's not user friendly tube swap.
I tested WE396A just like IFI support say's, one by one and one tube is working ok and other one truns ICan red.
I now wait for additional tube.

This review says that Topping DX7 Pro sounds almost as good as iDSD. "only" 5 times cheaper

That's the reality of diminishing returns. If this comes as a surprise, you have much to learn about our hobby.

hi i have few questions:

1- do the tube modes take effect on when the ifi idsd pro is used just as a dac when connected to ifi ican pro, or are the tubes only in effect from the headphone out of the ifi idsd pro

2- what setting u advise when i want to use the ifi idsd pro as a dac to my stax amp, output mode( hifi or pro fixed or variable ) , as the stax amps i guess like to have dacs that have good power output

3- what is the sync mode in the back on the right where the words DARS and Stand alone ... are

Pro iDSD's headphone out and line out are based on the same circuit, there's no separate headphone amplifier in this product. And yes, tube modes are always active if you turn them on on the product's front panel.

2- what setting u advise when i want to use the ifi idsd pro as a dac to my stax amp, output mode( hifi or pro fixed or variable ) , as the stax amps i guess like to have dacs that have good power output

If your Stax amp has a volume control (and most likely it has it), you want to set your Pro iDSD in the Hifi fixed mode to bypass Pro iDSD's volume control. Fixed means volume control bypassed, variable means it's active.

3- what is the sync mode in the back on the right where the words DARS and Stand alone ... are

These settings are useful if you have a standalone word clock. Please see Pro iDSD manual, it's all explained in there.
