On safety ...
I listened extensively to Tenor/Kharma and Lamm/Kharma in a controlled environment. I chose Tenor despite my own conerns about OTL safety. It seems one of the output tubes in one of my Tenors was, unbeknownst to me, damaged in shipment. As a result, shortly after setting up my system, the damaged tube arced or something (blue flash, loud pop, very scary). No damage whatsoever resulted to my Kharmas. After getting replacement tubes, the sound is magic.
