Thank you Anthony
It is clear now that the HXHE is ‘the memory player’.
Just for a better understanding, where does this actually  ‘reside’?
I thought it must be part of, an integral part of the PC.
Obviously it is ‘seperate’, as can be installed on even a laptop.
So now with my basic questions answered, (& reckoning that from what has been said, that an extremely high percentage of those using Tidal are not getting the best sound) I, as asked above, would just like this clarification as to the ‘relationship/usage’ of the ‘memory player’ to the Mach 111. 
Regards

Does anyone ‘see’ the PeterSt as St. Peter ? No response would be perhaps preferable.
To Peter’s reply re such as Tidal as against high resolution downloads & the practical benefit of using such as the Mach 111.
The Mach 111 is a “memory player”, (never saw it that way, but yes). Are all ‘dedicated audio PC’s seen to be, “memory players”?
OR, are you in fact saying, (in that you indicate ‘Tidal not really streaming’) that even the lowliest of PC’s or even laptops are in fact ‘playing’ as a “memory player “?
Can it be considered that a downloaded high resolution file needs a high level audio PC as against say the device required to play from such as Tidal?
IOW, would it be fair to say, that with such as Tidal, that a piece of music would be ‘deteriorated’ to a much lesser degree, than would a downloaded high resolution audio file if ‘played’ using a laptop PC?

Probably firstly an apology for posting directly here.
My ‘excuse’ being that it is only as to the Phasure Mach 111 Audio PC that caused me to contemplate this matter.
To keep it simple, I understand that a vastly superior device that Peter has made available can have a huge effect as to the processing of high resolution audio. Maybe nobody has stated ‘revolutionary’ as yet but this seems to be the basis of the overall comments.
But my question is that when using a ‘streaming service’ such as Tidal, (where I presume little actual ‘processing’ takes place) does the benefit of such a superior device come into play? Basically, to go to the other end of the scale, would a simple laptop PC , (except perhaps re USB for a noiser’ 5 volt line) give the same quality of sound?
