I demo'd some quad 2805 speakers with the amp, and ended up buying the amp! What got me was that when I went in I was just enjoying the music rather than thinking 'is this right, could it be better', etc.
Now at home and comparing to my old amp (a NVA 80w solid state) it definitely has a 'fuller' sound, and more little details that make the music sound real. Could be the extended frequency range and harmonics? I am driving Castle Harlech's here. Feels like it could drive anything. I don't listen to very loud music, and am always under 25% on the volume dial. It drove the quad 2805's with good bass, great sound.
I have had fantastic customer support from Roger Gibboni who built a 240v version, and has followed up with great support.
