Hi Merle,
What I’m using right now is an Opera T99 with 6922s and the Lotus/Clari t with Volume control.
This is an amazing combo. Best of both worlds and the volume control on the amp lets me dial in the perfect gain without fussing with resistors. The power is amazing and the pre has 24dB of gain. Vinnie is in the process of rounding up all the part for an extensive mod on the preamp.
Thanks again,
Louis
