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.

If your morrows are also brand new, then that's a major cause of sound oddities.  The Morrow cables absolutely REQUIRE around 400 hours of break in.  

The Morrow site explains this in great detail, they are not like most other brands since they have mainly solid core copper plated with silver.   I've got 3 pairs of Morrow RCA's and experienced this myself.  I decided against buying Morrow speaker cables for this reason.  I had left my system alone for about a month, and the Morrow cables needed an hour to get back to normal.
