I agree with your statement Shadorne. Most(not all) small bookshelves that I have owned seem to sound forced with pumped up bass in order to sound "big". After listening to the Harbeth speakers, I realized what I've been missing all this while. I'm quite smitten with the SHL-5 and Compact 7ES-3 now, more with the latter since it comes with the exotic tiger ebony finish which looks classier than the cherry(although the former has a bigger sound and bass due to the larger cabinet). Yes, the midrange is truly magical.
I would add, however, a big PMC with a 3 inch dome mid would also be magic and give you plenty of bass to boot!This I agree, but the bigger PMCs(EB1 and IB2) are not only more costly but need to be driven with Bryston amplification to sound "acceptable". Also, I don't think the midrange of the PMCs can match the surreal and lifelike sound of the Harbeth. I'll probably find a Bryston SST amp to drive my LB1 Sigs in my 2nd system later. As for now, it's the Harbeth for me.
