I have Dared DL2000 tube preamplifier great sounding one, preamplifier existing input selector switch used very poor quality, if I replaced with high quality gold plated contact switch (EIZZ Rotary Audio Input Selector switch) and Alps volume control replace with 24 step Attenuators Volume Control sound will improve? picture attached below. Please give expert advises. Raj

Depends on the type of alps pot used. Alps makes pots that range from the entry level to very high end sealed devices. Whats the pot part number ? If its the “blue velvet” then dont bother as it may be a lateral move. If not then you may hear a difference. Even if you swap with EIZZ it will have to be a part with similar ratings as the one used.

What makes you think the selector switch isnt doing its job ?

Why dont you tell us whats used currently as a pot and selector switch and then lets draw a conclusion.
