KT 88 Integrated amps


I am looking for an integrated amp to partner my Diapason Karis speakers.On my short list are Unison Research S2K and the Prima Luna prologue two.My room is quite small and I like acoustic music presented in a natural fahion.
Any recommendations on these or any other amps that would be available in UK.
Thanks

Check out the VAC Avatar Super, not sure of dealers in the UK. Contact Kevin Hayes, www.vac-amps.com.
The Nelson audio i65 is excellent! Not sure if available on your side of the pond.
