I am definitively using both pre-amp and headphone amp modes. I permanently connect RCA cable to a pre-main amp to drive my speaker system. If I want to listen to music through a head rig, of course pre-main amp is turned off. I do not see any issue with that.

I would have thought that too, but I just found it strange the manual suggested not doing that. Wanted to make sure there wasn't any kind of known issue with that setup.

I've some Western Electric 396a tubes that I'd like to try in an iFi Pro iCan and iDSD (have both) But I can not figure how to open up the case. Unscrewing the 4 main long screws from the back does not seem to allow it to open. Any simple trick?

Hope this helps.

You only need to unscrew the ones in the back panel.



I swapped mine a while back to the WE 2c51 (same as yours), they change for the better the sonic characteristics of the pro iCan.

Thank you, So it seems that besides the four long ones, all of the small ones around the sockets too, then lift off the back panel and the chassis will slide forward.

After all back screws & the plate was removed, and then a push, the chassis moved forward and I was able to change out the GE 5670 for WE 396A and what a difference. I'd previous replaced the 5670 in a Glow Amp One and found that the 396a conveyed more midrange presence forwardness, fullness and warmth with a sweeter treble. And in iFi, the same holds true.

Where did you get the WE396A tubes, if you don't mind me asking?

I got mine on Tube depot.

Same here. And then a pair for half the price on ebay recently, a pair that sounds even better. The ebay seemed like a steal at 99 dollars. A pair of these goes usually 150 plus.

I wouldn't mind $150.00pr, but they always seem pretty expensive when I decide to look.

I just checked Tube Depot and these tubes are $180.00US each, plus shipping since I am in Canada. I would be looking at about $500.00 in Canuck bucks, landed. And possibly/probably tax on top of that.
Too rich for me.

Haven't checked but it will probably not be cheaper if shipping to EU?

That is definitely something to consider!

Does anyone know if the fuse is replaceable on the Signature unit?

Just picked up this bad boy to pair with my Susvara. Will the sound change much over time, any run in period required ? I’ve never used tubes before and wasn’t sure if it changes much over time.

 

[Glokta]

Usually with tubes the sound changes in the first 50h or so, the frequency response starts to become more linear after that, that being said, the default tubes on the iCan Pro don't add too much to the equation, they add some depth and smoothness but if you want a real transformation then you should try and change them with some WE396A or Bendix 6385 (the process voids the warranty of course, your choice )
