Is there a point of diminished returns with amps and Harbeth 30.1s?


I’m currently using Herron M1As with my 30.1s and I’ve upgraded the rest of my system (Aries/Fatboy/SUT/DL103r and Lamm pre and phono) and each upgrade has been VERY satisfying. So is it going to be worth spending $5000 or so on the used market to upgrade the Herrons? Any thoughts as to whether I’ve reached the apex of amp/speaker performace for the M30.1s?

Alan Shaw has long welcomed any debate on his opinions regarding cables and amps.

He discourages it to the extent the forum was split into two sections, one for technical discussion based on facts and science while the other section was for subjective discussion on amplifiers or all things audio not endorsed by Harbeth. Your contribution may be welcomed at first, but after a while they will be shot down by the moderator and the cohorts if they don’t coincide with the values that the clan preaches. As Whipsaw had suggested above, your opinion or post will mostly be disparaged.

If you go a step further, the post which you made will be modified by the moderators or completely removed. I have forgotten if some users have been banned for posting few issues they experience with their new speakers. Issues such as glue marks on the main driver and defects on cabinet etc.

The forum used to be a free view as a non-member can read the content of the forum. It now requires a member to log on to the forum just to enter the forum. You wouldn’t be able to gain access to the content on the Harbeth site before you become a member.

This is an interesting issue when you think about it. It’s tough to conceptualize a business creating a public forum that includes people complaining about their products. I would think somewhere in the forum rules it probably states that matters such as those should be handled directly between the customer and the company. Or at least I’d understand if those were the defacto rules.

Yes that’s rather true as most companies would want to protect their image and reputation. However, there’s less transparency with such practices especially when the complaints are genuine. The member who once posted issues with his new C7ES3 was a friend. That post he made on the forum was removed by the moderator and I am not sure if he was banned from posting on the forum for couple of days or weeks. There were others who experienced the same, and just lately another case resurfaced as the owner highlighted his plight on a British forum.
@dhcod - Just remember that it doesn’t matter what anyone else hears, claims to hear or claims to tell you what you should hear. All that matters is what you hear in your home, in your system. Then you can relax and listen to beautiful music while others are too fired up trying to push their views onto you. I was a conservatory-trained musician in my youth and one thing I learned is not to assume someone else cannot hear something that you can’t.
Thanks @chayro! I’m plenty old and have been doing this for so long that I do know that. Also work tangential to the music business (feature film editor) and I have conversations with mixers and engineers all the time about how we all hear differently!
