Obviously I wasn’t comparing like for like as 15” Tannoys of any era are in a whole different price class to SHL5s, but for me the difference was scale, dynamics, realism, heft etc, plus more importantly there was something I did not get on with in the Harbeth’s crossover region. I could hear something I didn’t like between the plastic cone and metal tweeters around 3.5kHz or so, right in the vocal sibilance range where our ears are so critical. I seem very sensitive to crossovers and phase for some reason, but when I pointed to it others they heard it too. The Tannoy’s colouration is far more benign for my priorities and even after a decade or more doesn’t bug me in the slightest. It just doesn’t get in the way for me. I’ve owned two pairs of Harbeths, C7ES and SHL5 and they both had the same flaw for me. Crossover region aside I really liked them both. If I ever need to downsize to one system I’ll likely end up with a mid-sized BBC box, but I’d be looking at maybe the Graham 5/9 as they sound seamless from what I’ve heard, as do real vintage BBC designs like the LS3/5A, LS5/8 etc.
