Has anyone compared K150 tubes and the stock EL34s in Primaluna integrated/amplifiers?

I have a Primaluna Dialogue HP Premium with stock EL34s.  When the EL34s wear out, which I suspect will be a long time, what would I replace them with?  The KT150 is intriguing to me. 

Has anyone compared these tubes, especially in Primaluna gear?  I'm wondering if I would lose the EL34s midrange in exchange for the increased power of KT150s.  It's hard to find, however, a bad review of anyone using KT150s. 

Thanks all!

I have the Dialogue Premium rather then the HP .

I have found the Shuguang Black Treasure 6CA7's to be to my liking . Your stock EL-34's are quite good for that type of tube . I have tried many different brands of EL-34's .

I have also tried the KT-120's . They have a nice top and bottom range but I found them lacking in the midrange . The mids are where the EL-34's tend to shine .

Some of my journey , into tube rolling with the Dialogue Premium integrated , is documented here in 1 or 2 threads for both the power tubes and the small signal tubes .

Good luck
