Can a DAC do double duty?

Only 1 XLR cable?

Sorry, my bad.  You are correct and I meant one pair of XLR interconnects.  Both your CD player and streamer should be able to flow through just the XLR interconnects from the Pontus (no RCA interconnects needed), and if the Krell is fully balanced that’s sonically probably the better way to go along with not having to potentially have to buy another pair of RCA interconnects.

Thank you @soix! No actually that's MY bad, I should have known that's what you meant😖. So both devices would then share the same inputs? Wow would have never thought that possible. That would be weird though because I have the XLR named as "Eversolo" and the cd player as "Elite" on the Krell. So I would then just always keep it as "Eversolo" but I'd still be able to play the CD player under the "Eversolo" input, right? 

Full disclosure I already have the CD player connected to DENAFRIPS Ares DAC but would like to sell that DAC and declutter my system a bit which is what prompted me to inquire about this,,,,

No harm at all the 8 is their best have a smps on the digital and a linear supply on the analog end ,and the new AKM 99 ES chips are very non bright.

and several adjustments soft roll off 1 I think sounds like a R2R in many ways with very good detail. Ever solo excellent new company I checked out their app 

very well thought out and a good 2T stick SSdrive  a audio associate  has a Western digital Black $110:and 2 minutes to install kills the node 

the 6 master edition for under $1250:is also very respectable sounding 

and they sell a LPS for $300 Thst easy to install on the model 6 through Denafrips .

So I would then just always keep it as "Eversolo" but I'd still be able to play the CD player under the "Eversolo" input, right? 

That’s exactly right.  Maybe renaming the Krell input to “Pontus” would be a little less confusing?

What pioneer CD are you running ?
