I'd like to hear your opinion about the pairing amplifier I intend to buy for my Tannoy Revolution XT8F speakers. The following amplifiers are considered (new):
- Unison Research Unico Primo
- Naim Nait XS2
- Roksan K3
- Rega Elicit-R
Music will listen digital via Chord Qutest.
I want to buy a clean stereo amplifier - all-rounder.

Thanks in advance,
