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!

Just bought a lightly used matched quad of Tung-Sol KT-120 for my Primaluna Dialogue Premium. Initial reaction is wow, where did all that bottom end come from?   Next reaction was where did that sweet accurate midrange go?  
Looking for something in between. KT-88 maybe?  
I still have a lot of listening to do before I really get a clear opinion on the KT-120. If you are looking for extra punch the KT-120 makes a positive initial impression.

Little late chiming back in on this thread, lots of music to listen to 😀

I am am now running all Gold Lions in my Primaluna. Six of the ECC82/12AU7 Gold Lion reissue and four KT-88.   Beautiful mids and highs, bass is deep and accurate when the recording delivers it. Very accurate, very happy.
