I've owned both and I would never say the HL5 is more agressive than the M30. They bear a strong sonic similarity. The M30 was build as a BBC drop in, so the cabinet size was fixed from the start. The HL5 allowed the company to build what they wanted without the constraint of a pre-set box. The HL5 is more forgiving of lower-end electronics IMO and throws a bigger soundstage, although the M30, as a true monitor, is somewhat more precise. They are both great speakers, but I would go for the HL5 if your room was on the larger side. BTW, I belive all Harbeths use metal tweeters, although the M30 uses a "better, more expensive" one. It's not about the tweeter material, it's how its utilized in the design that makes a tweeter harsh or spitty. Harbeth crosses the HL5 over at about 4K, MUCH higher than the usual 2.5K or so many designers use. This keeps the low-end grunge out of the tweeters, which the designer believes can cause problems. Anyway, that's my opinion.
Harbeth HL5 vs M30
Ok boys, I can't audition either one...no dealer in site. I have owned compact 7es3, so I know the harbeth sound and I want it back, but with more resolution. I have read countless reviews, but I want your thoughts. Yeah I know, use the Harbeth user forum...not a member, this is easier. I will be using a big SS amp in a 23x28
basement with 9' ceilings. The size of the M30 would be nice, but if the HL5 is the sweet spot, as some suggest, I will make them work. Thanks,Mike
