Back to trying to upgrade Harbeth 30.1s


I'm hoping someone has done some of the work for me. I've upgraded everything else and now I'm back trying to improve on my Harbeth 30.1s. The issue is space. I need either another stand mount or a small floor stander with a similar footprint because of my listening space. I'm 8 feet from the speakers, so it's near field listening. I'm generally happy with the Harbeths but I'm hoping to squeeze out some extra dynamics and bass without sacrificing tonality. Especially interested in anyone that has done listening tests with the 30.1 vs other speakers.

I've owned the M30s and now the P3.  The Purist Poseidon speaker cables made a dramatic change in the P3s, making them sound much bigger and with deeper, better bass.  I never tried them with the M30s, but I think it's worth looking into. Sounds like they might give you exactly what you want.  
M30.1 is my least favorite speaker with the Harbeth line (M30 is worst with rolled off treble and a warm and dark sound). As others have mentioned, the P3ESR is worth considering. Another option if you want to get out of Harbeth is Marten, either Oscar Duo or Duke 2. Be prepared to upgrade the rest of the components to get the best out of the Marten as it is a very revealing speaker which will reveal any shortcomings with partnering equipment and cables.
I wonder how much difference the 30.2 Anniversary and now the 30.2 XD makes.  There are definitely in-room differences between the 40.1 and 40.2.
The 30.2 XD is the same as the 30.2 anniversary with more choices on the finish. A good buddy of mine owned the 30.2 anniversary and sold them after six months. They are not everyone’s cup of tea!
