Hi gregvet,
Yes I could hear HEED Enigma speakers.
They are great. Small size but perfect sound including bass reproduction. Very transparent, fast and clear delivery.
I could hear them in Bristol HIFI show as well. With using the Roksan Xerxes the Enigma was shining on a level which I considered among the best 5 speakers of the show including much more expensive alternatives as well.
Because of the non-directional concept these speakers do not have a "sweet spot", you can enjoy stereo sound anywhere in your room.
when I was able to listen to the Enigma first I already ordered my Spendor speakers (S5e) which are great but Enigma's bass is even better.
I am using HEED amps for the last six years and enjoying every minute listening to any kind of music.
