The P3 is a scaled down version of the Harbeth sound. I think you will notice it in a small room. I would say the C7 sounds more like the SHL5 than the P3. The P3 is more involving but you will miss the fullness.
I ran the Naim Nait 5i2 and Harbeth combo for a while and there was not a hint of brightness. In fact it sounded a bit rolled off on top. The bigger Naim stuff is more forward though.
If you use Naim, best to use their wire and interconnects.
I auditioned Harbeths using largish Japanese amps from Accuphase, Marantz and Airtight. I use a 100 wpc Yamaha. With these amps and using modest wire from Kimber, Atlas and Oyaide, I have never noticed brightness.
That said, both the M30.1 and SHL5 are highly resolving so if you have brightness or edge elsewhere in the system, they will definitely reproduce it.
Best to go find a place to listen for yourself. BTW in Canada Harbeth speakers are sold at full MSRP - no discounts - although I did get a good break on the stands.
