Rethm Maargra Speaker: High efficiency, very easy impedance, built for SET amps.

These, very easy to drive Rethm speakers

Quite the opposite of the very hard to drive, (most of the Wilson) range of speakers.

Read the listening test reviews and the lab tests on both and make up your own mind, about each, and what will sound the best and more truthful to the recordings.

I heard the Baahva and it was not coherent.
At higher volume levels you can hear the cabinet vibrate.
I have owned a pair of Maarga which I thought sounded very detailed (and no cabinet vibration) Actually sold them and bought a pair of the Saadhana (top of the line in Rethm speakers) and have been nothing but amazed. I drive them with a 24 watt Audion KT120. I think sounds more detailed than my buddies B&W 800D3. There are  bass level control that goes from Lo to Hi; and a crossover frequency control that goes from 60 to 240 (Hz) with a detent at 120 on the back that need to be set to the listening room. If you don’t adjust these to your room, it can give enough bass to vibrate a little, but adjusting them will give plenty of bass and no distortion or vibration. If you can listen to them again and the owner allows you to adjust it to the room, I think you will be pleased (and your friend thankful)
I was hoping Charney was going to be at AXPONA and I don't see Rethm either.  I did hear a set of Tannoys that I thought sounded pretty good driven by Pathos.I also heard the Wilson Sasha/DAW driven by Audio Research and it was not the best sounding system in the dealership. After all these years and all the media love given to Wilson, I was disappointed. But that is just me.
