@alvinnir2 I will likely try something solid state, and see if it yields any improvement. There seems to be enough opinion here to support the fact that a preamp will improve things
Yep! This is the logical and most thorough approach. Compare both options and listen for yourself. Audio forums have endless threads about active preamp versus passive/direct connection to amplifier. Quite a few experience listeners have tried both and (As expected) each choice has its advocates.
In my listening experience, the use of a high quality active preamplifier provides The better sounding option. However, that’s just my outcome experience and you need to find out for yourself.
