Pre amp for Anthem 225

The Rotel RC-1590 MKII would be an excellent choice, wilchech.

Thank you all. Also thinking about parasound p6 and a21+

You might also consider the Rotel RB-1590. I use one and it is excellent.

I would choose a preamplifier very carefully. Typically I would spend more on a preamp than an amp. It really determines the overall quality and tone of the music you hear. I would choose a preamp first, then an amp.

I have been choosing and upgrading my system for nearly fifty years. You can see my current system by clicking on my ID.
