Judging by the music that you like and your preference for a warm presentation I would take a hard look at the new Sonus Faber Serafino. Just to be fair this is not what's in my listening room but I think they would be a very good fit for you. If you're interested in more low end, I'll bet that you can find a used pair of the larger SF Amati second hand in your price range.
New speakers for 15*12 room powered by Lamm 1.2s?
Attending the Seattle show this week. Thinking about upgrading my Thiel 7.2 speakers which I have owned for over 15 years. I have a dedicated room. My Thiel's are powered by Lamm 1.2s direct from a PS Audio Directream DAC Mk1. I am separately looking at upgrading the digital sources and potentially adding real to reel to my system. Through room treatments and upgrading the Tubes in my Lamm's I have been able to get a lot of the brightness out of my Thiels but I am still looking for more warmth and definition. I listed to a lot of female vocalist music, acoustic/electric guitar. I am told the Borreson X3, X6 are an incredible value. Any recommendations to consider? Thx
