Just take any tube preamp and change the caps to oil caps so you get a warm, tube like sound. It is that simple. You can also changeout the filament resistor to adjust the voltage to the tubes and warm up the sound (relax the sond). No need to try different preamps if that is all you are looking for.
the best 'tubey amp - warm,smooth,liquid' ?
i'm using the word 'tube' as the meaning of warm,smooth and liquid sound.
but i could't compare to some tube amps like mcintosh(mc275), cary(cad 805), arc(vs115) and conrad-johnson(premier) at one place and the same time.
some say mcintosh lean, cary weak and not bloom, arc not tubey and cj no clarity.
i need your experiences and advices.
actually i have a difficulty to match speaker systems with.
