Harbeth - Audio Research?

Harbeth are delicious sounding! You are in for a treat.

I have the Harbeth HL-5's and they sound spectacular. Seems like when I upgrade, they also rise to the occassion.

Have tried Harbeth with Cary,McIntosh and Bruce Moore with great results.
If you are into heavier rock, you may prefer the M30 over the 5s and 7s. You won't be disappointed with any of these speakers, truly musical.
Heard the 40.1 at RMAF and felt is bested many of the mega buck speakers. But it seems to need a very big room.

I have owned Thiels for many years and using a pairs of 3.6 now. I am thinking of moving to a new direction as I am getting tired of listening only to good recordings. Some recordings sounded terrible on Thiels. I listened to Harbeth once and I thought it is more musical and natural than my Thiels. Will I loose out by changing?

the audio research and harbeths will go well.
Go for the SHL5s although the M30s are also quite nice.
The Harbeths for that matter will go with most amps.
