Vinnie Rossi L2i SE Integrated Amplifier with PHONO stage and DAC see here
’’The really interesting bit, however, is found right next to each EH300B tube’s Yamamoto Teflon socket: a toggle switch. When these are switched leftward—as shipped from Rossi’s Massachusetts shop—the preamp stage runs through the dimly glowing EH300Bs. Flip the toggles to the right and the EH300Bs are bypassed, the preamp then running in solid-state mode via a class-A JFET stage. The former route provides 32dB of voltage gain, the latter 24dB. This is very cool (see below). On the L2i-SE’s rear panel are one pair of balanced (XLR) and two pairs of unbalanced (RCA) inputs, and one pair each of balanced and unbalanced outputs.’’
