Uno Vs Kharma

If you love the sound of your system, why trade? To me, the sound of an AG system is so completely different from the Kharma Ceramique that I can't imagine anyone liking both. For my own taste, I MUCH prefer the AG. I've listened a lot to AG Duos and find them to be pretty good speakers. By comparison, the Kharmas sound, to me, brittle and mechanical and surprisingly dynamically dull and unengaging. But, that is my personal take.

If you find a low efficiency speaker that you like, then of course you need the right kind of amp to drive them. But, it is pretty hard to find a high-powered amp of any kind, tube or solid state, that will do what a SET can do. You must audition your prospective purchases with this in mind. To make the kind of wholesale change you are thinking about, you must also audition amps at the same time; hoping to find an amp that works like a SET with a low efficiency speaker is simply not realistic.

My point was not that Kharmas are bad, that is a matter of taste, but that the amp/speaker must be considered as a combination. When one goes from low power to high power requirements, one should not expect to find a high-power equivalent, such may not exist.

I agree with Ejlif that the "problem" with the AG Duos lies in the bass. It does tend to have a bit of one note emphasis, and there can be problems making it integrate with the two horns. I do disagree just a bit on dynamics. To me good dynamic performance does not require turning up the volume to sound dynamic. In fact, that is an indication of poor dynamic performance. I find that good low powered amps can sound more dynamic than high powered amps, provided the speakers are efficient enough and one does not try for extremely high volume. I don't consider artificial edginess to be good dynamics -- natural sound is part of dynamic performance too. An overall sense of liveliness and a kind of "presence" (like the performer is right there in front of you) is what I consider good dynamic performance -- I find this to be a very rare thing with so many, even expensive, speaker/amp systems.
