I just got back a silver bumper Naim 42 pre / 110 amp from AV options. Chris recapped, cleaned and tweaked them out to near NOS (new old stock) status. Seeing as I just got in some Guru QM102 to play with, I decided to throw ’em on. Hell Yeah! Classic Julian Vereker Naim! Guru claim the small QM102 are 30hz to 30khz. It sounds like it. The bass is big, deep, tuneful and controlled. Along with the old school Naim it just hooks you in and grooves!
