I have written about how I am a fan of his honest opinion. I do really think it is great, no audiophile snobishness.
I also want to give a shout out to how responsive he can be. I e-mailed him tonight for advice on digital SLRs as my sister is looking into buying one. 12 minutes later I got two suggestions with follow up questions to help narrow it further.
Kudos Don to being a great guy!
Check out his great blog and glossary of audio visual terms.
