Kelly Transducers KT3 on Soundcare Superspikes Beautiful floor-standing speakers with a high sensitivity of 91dBa. Fantastic with a tube amplifier. With my own hybrid amplifier, they create a huge image with a beautiful placement and a lot of detail. The tweeters radiate very nicely and reach the listening height pleasantly. They let you experience the music in a natural way. They display large orchestral works very easily and pleasantly. Of the hundreds of sets I have already had, this set belongs to the absolute top.
