i have a DIY voxativs based on the AF-2.6. Its like their new FIT towers. I have a REL S/5 SHO integrated as well as TAKET BatPro2 super tweeters. I drive all this with low power amplifiers. Lately, i have been driving them directly with a Chord Hugo2. The 1 watt headphone amp is mostly about 50-60% volume and sounds, well, incredible.
I think efficient, point source drivers driven like headphones are the future for nearfield listening. Every type of music I throw at this sounds great.
