It looks like something is broken on this webpage. Is this supposed to be just one page and done? Or, were there more pages to follow?

It's fixed after my comment

It was broken before. It must been fixed before you checked it. Judging by the pedigree of your website maintenance I've observed so far, I afraid it's a matter of time until Stereophile is hacked.

Halfway through posting the 5 pages of the review, I realized that I needed to clear the website's caches in order for all the pages to appear correctly. I did that then responded to your comment.

I forgot how well Martin writes.

He, like Art Dudley, mastered the art of writing. Every sentence flows beautifully like prose. Observations are succinct in intent and insight. I now 'know' that this amp is more accomplished than its last iteration. Welcome back!

I would love to hear more Naim gear at next year's AXPONA.
