Most preamps have multiple stages with a unity gain output buffer being the final one. The objective is lowering output impedance and the 6H30 is well suited to that function. Different companies choose tube or SS for either gain or buffer.VTL and PS Audio take the opposite approach of the SP20 by *bolting* a MOSFET buffer to the 12AX7 or 12AU7 based gain stage for the 7.5 or BHK Signature.
And I would hope that these five figure ARC tube preamps sound like tubes.
My goal is for components to sound neither *like* tubes nor SS.
