Check out the Lejonklou website, and see if this line might meet your requirements. I would say that it is neutral, rather than warm, but for the type of music you listen to......neutral may work best IMO. But, ymmv. Good luck.
"warm" solid state integrated amplifier
I am interested in purchasing a new solid state integrated amplifier in the $6000 to $8000 price range. As I am getting older I am finding many amplifiers to be uncomfortable to my ears, "bright" is the term I see frequently used. I am looking for an amplifier that is "warm". Thank you and I appreciate any advice I receive from Audiogon members.
