Fiio K5 Pro vs Seperate DAC+AMP for Fostex t50rp Mk3

[wrigglycheese]

Greetings, so many sections I hope this is somewhat appropriate.

Currently I have a choice.

Fostex T50rp Mk3 + Fiio K5 Pro

Or

Fostex T50rp Mk3 + Cambridge Audio DacMagic 100 and a dedicated Headphone AMP worth £150-200. (I am in the UK)

I would be supremely appreciative of any thoughts here as I am NEW to this. If the latter, what AMP recommendations ? I would be looking for something with plenty of juice to bring out the BEST from the Fostex, the Fiio works FINE, and plenty loud enough, however, I understand that is something different compared to having PLENTY of power which brings out the best in the difficult Fostex Mk3

I am NEW, so really open to learning and suggestions.

Many thanks.

(PS as for the sound I like, it's warm, BALANCED, and I am sensitive to harsh treble)

Well, I went with SMSL SP200 and CA DacMagic 100

The Fiio K5 Pro is a nice bit of kit but just wanted a bit more headrooom for the Fostex.

Cheers.
