Why do Harbeth speakers have such a cult following

This question was asked five years ago and I it as pertinent today as it was then. There a lots of great speakers that don't have the following as Harbeth. My guess would a combination of factors such as neutral sound, half decent cabinetry, Stereophile reviews and the British mystique. I got sucked in. I wanted to upgrade my PSER3's and it was easier to go back to where I purchased them and listen to something in the same family. I now own the 30.1's but it took 4 amps to get the sound I wanted. Started with NAD M2, Arcam, Moon and now LFD NFSE Mk II. Without the latest amp, I would have sold these speakers. 

Bozak did Harberth better back in the 60's!  Time to move on...unless your talking 60's pricing.  

As speaker cables for my Super HL5+ I am now using Duelund DCA16GA tinned-copper tone wire that I read about on Jeff Day's website. I replaced a pair of Audioquest Castle Rock with them. To me they strike the right balance with the Harbeth's but YMMV. I have also used Cardas Golden Reference. All three of these speaker cables work well with the Harbeth's IMHO, I just prefer the Dueland.

My Resonant Woods stands are in and I'm picking them up tomorrow afternoon. I can't wait to hear the difference with the open bottom stands. I use Skylan stands with my C7's for years and now the only stands I've heard my new SHL5 Plus's on are also closed bottom. I'm thinking the sound will be noticeably different, for better or for worse. Crossing my fingers.

well I found very nice sinergy between harbeth shl5 and synthesis roma 37dc+ amp
