Don't know about what’s available in your area AND I'm a big Naim fan but………
With both my Avondaled NAP 110 and my NAP 110 with Phoenix boards, I used to have a 32.5 with some Neil Jadman’s boards fed by a CB Hicap with an Avondale TPR4. I also tried this pre/hicap with my NAP 160 BD.
I must admit that this pre/Hicap setup was very very good but I wanted a remote so I tried a few other things.
I finally ended up with a Classé Audio CP 35 from the 90's to feed my NAP 110.
Surprisingly, all the famous Naim’s PRaT is still there, nothing missing in terms of dynamic and as a bonus, the sound is more open, organic and natural, the female voices and cymbals are now perfect.
I also didn’t lose any bass depth and slam Naim is known for as well.
I got this Classe Audio CP 35 on fleebay for $300.00 CDN, put new caps for another $50.00 CDN and this little and humble preamp really stopped my upgraditis.
As I said, I’m a big Naim fan but some times, the solution might be something else.
