Audio Analogue Donizetti monoblocks

[CONAN]

I have audio analogue donizetti monoblocks which are connected to Yamaha AVR. I would like to know if l can connect a second preamp to the donizettis as they individually have "stereo RCA inputs", as l find the Yamaha preamp does not do justice to the donizettis and my quad Z2 speakers.

Yes, that is really easy to do in a number of ways. The simplest way is to buy an RCA switchbox with 2 pairs of RCA inputs and 1 pair of output sockets. You can get these for £10 used or maybe £20 to £30 new on ebay. Simple, uncomplicated switching.
Alternatively, your Yamaha AVR may have a set of 'straight through' RCA inputs which are designed to feed a stereo preamp into, the signal then goes through very little of the circuitry in the AVR, and therefore is unaffected by it, but then also goes into your Donizetis.
