I'm on my second Primaluna. The first was a Dialogue One, and now I have an HP integrated. I've never had a moment of trouble, and love the sound. The One I had for four years, and the new one I've had for two.
I did upgrade to the KT150s, and noticed the same increase in bass, while keeping most of the midrange goodness as the EL34s. I can't say I have experience with the others listed here, but I can highly recommend the PL.
Even better, there is one for sale here on the 'Gon for a healthy discount from new. No, I have no relationship with the seller... just noticed it there.
