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.
