Help Tannoy XT6F with Primaluna

Hello all.
Just got a pair of Tannoy Revolution XT6F speakers. They are supposed to replace KEF LS50s. I'm driving them with a Primaluna Prologue Premium power amp. The new Tannoys sound awful with the Primaluna. Very peaky upper midrange and not much bass. Pretty unlistenable. Tried them with my old Rotel RB990 solid state power amp and they sound much much better. Tried the 4 and 8 ohm taps. Tried the stock Primaluna tubes and some KT 150s. No good. The Primaluna sounds great with the KEFs. Any ideas? Thanks in advance.

Solid state Rotel amp. I don't think there is any hope for the Primaluna with these Tannoys.

Rotel SS amp: Bi wire brought the peak back out some. Shot gun made no change I could hear.

honashagen, i guess the only other  thing I can suggest is to try the KLEI gzero6 speaker cables. They really are excellent.

When I heard them ffor the first time the depth and control of the bass left me speechless and their smoothness in the top end is superb. Their biggeset asset being their clarity, imaging and dynamics

I first tried the gzero2, their lower end model, which are now on my A/V system. Also a very good performer.

They may also perform miracles with the Primaluna.

 Well I have about 60 to 70 hours on the speakers I believe. Morrow Audio says it will probably take at least 200 hours. I have them set up out-of-the-way facing each other as close as I could get them with a mono signal and wired out of phase.  I'm going to play them 24 hours a day for five days and see what happens.  That should get me close to 200 hours total.

The Klei cables appear awesome.  It scares me though to spend $800 on new cables.

I knew the reason once but I forgot it, but cables break in better if you give them about an 8 hr " rest"  every other day .
