its clear Helomech has some sort of negative bias towards harbeth. saying that Spendor, stirling, graham are all better then Harbeth seem very bold statement. to be able to claim this, one would have to have all the same type of model from every brand in the same room. he have not done this. he just like to shit on harbeth.
what I did do is compare P3esr and shl5plus with graham ls59 in my room for a few months and preferred to keep shl5plus
I also compared different spendor model vs p3esr and in every case the p3esr was better in tonality and overall performance apart from bass
For op, the shl5plus goes surprisingly deep when well placed in room, down to 30hz flat with room gain.
