Just received my Will Vincent Dyna Super 70 amp with 6L6's with triode output of 21 watts per channel. Wow!!! Right out of the box this thing is transparent and detailed with warmth in the midrange with nice tight bass. The retrieval of low level information is astonishing with my 96db Omega MaxHemp V2's (and I didn't even get my Lightspeed preamp yet! When it sees 470K ohm input impedance of Will's amp, I'm sure things will really get cooking! Thank you Will.
