Warm Tube Amp(s) to Tame Hyper-Accurate Speakers?

I had a similar experience to the OP breaking in a pair of Harbeth 40.2 Anni's.  I solved the problem by positioning GIK 244 free standing panels parallel to the side and in front of each speaker, which addressed the first side reflection points.  While I no longer need or use the free standing panels, they did successfully solve a problem while my speakers were settling in.  If you are within driving distance to St. Louis, the GIK panels are available.

OP,

How long have you had the equipment and speakers? Did you get everything at the same time? What did you have before? Room size? Setup? 

All the best.

Not looking to hijack this thread, but how would you put a ground wire on a speaker?

Thanks

please take note of the suggestions I mentioned in the D9.2 run in thread.  

however amplifiers and tubes (with tube amps) do also make a difference.

My D7s sounded excellent with a Rogue Audio Cronus Magnum II as well as a Rogue Audio RP-7 preamp and Stereo 100 amplifier.  The RP-7 and Stereo 100 are very dark sounding pieces.  

This is why god invented tone/eq controls.

Ok...I will turn in my audiophile card now.

Many modern speakers seem to have an emphasised treble.That seems to be the way the world has gone-more of everything is considered better! They should come with an L pad so you can adjust the output .You could have them installed and say mounted on the back.
