@fai_v Hi, You can use the Musetec 005 without a pre-amp because it has a built in volume control which doesn't take much away. However a good pre-amp will give you a bigger, wider, deeper soundstage.
I prefer SS amps and pre-amps because they don't distort the sound but good SS is usually more expensive than valve equipment.
Usual suspects are Nelson Pass designs (Threshold, Pass etc.), Mark Levinson (but the power cable is underneath), Spectral (glorious but expensive), Conrad Johnson (SS and Valve).
I use SMC but they are hard to find.
Many more but these are among the best.
