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.

The Tannoys have a 90db sensitivity rating so the Primaluna should drive them fine. Have they had time to break in? I would play them for at least 50 to 100 hours before critically listening. Also, cables make a big difference, what are you using? Some speakers just don't like tube power. I would never use tubes in the power amp section to drive my Dynaudio speakers. They do not like tube power. So I use tubes (10 of them ) in the pre amp section to inject that tube quality I love.


Regards,

Matt


  

P.S. I would do what ever, to get those Tannoy's sounding right, great choice!

Give them a month to break in. Hopefully, they will sound much better. Mine did -- not the same model, though.

I had used a Japanese Triode integrated 300B amplifier with a pair of Tannoy DC 8's and that sounded really really good.
