Headphone amp suggestions - Focal Clear

[Entrigo]

Hello wise headfi fok...

So - just bought a pair of Focal Clear, and currently using them with a Topping DX7 Pro.

I like the Topping well enough, but need analogue line in so can connect to my amp and listen to records through headphones.

I need suggestions for:

A: DAC + amp combo with RCA line in to replace the Topping

Or

B: just a headphone - and can keep the Topping as DAC (also as it is on for sale and no bites)

Budget around £300 max (used very much my go-to).

Neutral sound and "drive".

I was thinking about Fiio K7 but I also read the Focal don't do too well with THX amps - the Clear sound good to me with the Topping but I am new to "head-fi" so have no yardstick...

Was also looking at Arcam rHead but I read it could be a bit "soft".

Any suggestions welcome.
