Valinar, I use and have used three very different amps for the Harbeth 30.1's: Naim 5i was ok but not very exciting, it's now sold. Still own and use: Jadis 30 watt tube amp, it is great but not a very punchy sound. Accuphase P-300 vintage solid state 150 watts, gives a big full and very nice sound. For fun, I would have liked to try a lot more amps, as they indeed do make a big difference in my opinion.
For the Dynaudio's (Focus 160) I used to own (I miss them a bit to be honest, but as I wrote, they didn't work very well in my room) a Rotel and tube McIntosh, very different from eachother, the Rotel was more clean and the McIntosh gave a richer sound but was a little "slow" in the bass.
I also own the small Harbeth P3ESR that I like very much and I don't need a sub at all! It's a very "versatile" speaker, suits every genre music is great fun with them. For vocals, the Harbeth 30.1 speakers are extraordinary, so real!
