High efficiency speakers

Hi all, thank you for your suggestions. I have the Kharma 3.2.2s which are borderline efficient at 90dB and not getting the full benefits of the SET design from what I've been told, but probably Ok in my current smallish room. Going forward I am looking for full range SET friendly, high efficiency speakers. No more of the Kharma limp bass I hope. I do have pre-conceived biases against side-firing woofers and powered woofers, but maybe unfounded.

Jax2, I haven't had the pleasure of hearing the Concident. My bias against side firing woofers is from listening to one of the models from Rockport. I heard less integrated bass, the same way some people would say about the rear firing woofers of the Verity speakers. My bias against powered bass in high efficiecy speakers is just a thought that since these designs use transistor amps for ther woofers, are they forgoing the supposedly sonic superiority of SET over SS amps (even in the bass quality.)?

Amfibius, your Acapella speakers look very cool indeed. Aesthetics is important to me. While my little Kharma's are not perfect match for my soon-to-arrive SET amps, and have limp bass, at least my wife doesn't complain. If i brought in the Avangarde Trios, I think she would scream:). So I need to avoid big broad cabinet designs if I could and there goes Tannoy.

Hi Jax2, your advice noted. I listened mostly to light classics and folks, and occasionally big scale music. My current room is only 10' x 14'. I have an opportunity to build a bigger one (perhaps 18' x 20'). The hi efficiency speakers are meant for that room for which I would like full-range and life-sized reproduction of the music I love. For many years till recently, I have always used SS amps...Classe, Pass labs, Goldmund. Just my experience, they had been good in many ways. But at the end of the days, i feel them collectively to be a little cold and sterile.

Hi Darkmoebius, I have a pair of Kharma 3.2.2 (borderline efficient at 90dB) driven by Goldmund Telos amps. I wasn't touched by the combination. Since the matching of kharma and Lamm has been well chronicled, I ordered the Lamm ML2.1s at risk without hearing. But I did phone up the Kharma factory and was told the ML2.1s are "perfect match" for my speakers. The amps haven't arrived, so I shall see.

Hi, I finally received my Lamm ML2.1's, and am burning them in. I haven't gotten myself a pair of high efficiency speakers yet. I am still using the Kharma 3.2.2. I have a qn to ask and hope someone can enlighten me.
The ML2.1's have 4, 8, and 16 ohm taps. My speaker's nominal impedance is 4 ohm (and can dip to 3.5 ohm). My assumption is to use the 4 ohm taps of the ML2.1's. But if so, what is the technical reason for that? And is there any reason to try out the higher ohm taps? And if yes, why?
Thanks.
