Like you I would naturally incline to KT150s and wonder why the unit costs $400 less with these vs. stock EL34. 

Are you in the U.S.? If so, I'm not sure where you're getting those prices. At Upscale Audio — the natural place to buy PrimaLuna because Upscale's Kevin Deal is the brand's U.S. importer — the EVO 400 is on sale for $4,995. That's with 8 EL34s. With a set of KT150s, the price is $5,715.

@passthedutchie Thanks for correction. I was comparing the $5,715 "sale price" at Upscale against what is apparently their "regular" price of $6,178 with KT150s. You are correct that the price with EL34s is $4,995. And of course I agree that if one is going to buy PL, one should do it at Upscale.

@ditusa , the article you posted mentions several times that balanced operation was developed to make super long telephone line runs possible and adopted by the pro-audio industry for long cable runs between the mics and subsequent electronics. Sounds kinda like what I said in my post. 

Your article is also chalk full of vague generalities like this, "Balanced lines offer advantages even if the connection is only 6" long, although it is also helpful for longer distances."

While this may be technically true, so is saying that spitting into the ocean raises its overall volume of water. Any minute "advantages" a balanced operation has on a sub 15-20ft cable runs are, in most cases, inaudible and nowhere near worth the huge additional cost. Getting an amp that sounds great is priority 1. That amp having XLRs is a distance 4th place on my priority list.
