I want to add a bit of "warm tubish" sound to my system, but I don't feel like replacing my current integrated amp at the moment. Would it be a good idea to add a tube preamp before my integrated amp? I am thinking of getting something used in the 500-1000$ range.
Here is my current setup (mainly for music):
Speakers: Paradigm Studio 20s v3
Amp: Rega Brio
Sources: Sony SCD-CE595 (SACD-CD), and PC with semi-pro sound card.
