I recently had the pleasure to try out the new Carolina Audio speaker cables and digital interconnects, and much to my surprise, my Kestrals really came to life. Although they are not flat, they are quite thin. Have you thought of going through the floor, under the fireplace, and back up on the other side.
There is a remarkably clear sense of musical timing and spaciousness that is a joy to listen too. The bottom end went deeper, and tighter. The mid range really opened up, vocals remained clear and sweet, but the level of detail and depth of soundstage really stunned me. I have a small room and the sound was just so huge I thought the walls were stretching! The upper midrange and highs really expanded without any loss of coherency, clarity without strain. On the whole, depth of soundstage, super tight yet coherent extension in the bass, and detail like I have not heard. I’m not joking when I say that I heard things in my music that I have never heard before. These are very natural sounding cables and interconnects.
Basically I’ve just had a blast re-listening to my collection. From Beethovens' 9th, with John Gardner, Lucinda Williams Car Wheels on a Gravel Road, Steely Dan’s, Aja, Diana Krall’s Live in Paris, (unreal ambience) & Miles Davis’s Bags Groove, (when was that recorded!?!) Like you I don't listen at really loud volumes.
It’s just silly not to try these cables, you won’t believe what you’ve been missing.
