I agree, the Harbeth SHL5 is not particularly fussy to sound good. For me they worked best with SS amps (Audiosector Patek 40w/ch) and solid core speaker cables (DNM Reson cables). Like most speakers they do need some care with choice of stands and room positioning for a well balanced bass response. But once dialed in, they offer a very pleasing (non-clinical) sound in either a medium or large room. The construction of the speaker and its veneer finish are excellent.
Acoustic Zen Adagio vs. Harbeth S-HL5
Can anyone give me some insight into these speakers? The Harbeths are about $1500 more so I would like to know if they are worth the extra money.
