I purchased the NEW DCA-33 back in 1996 along with the P-3 preamplifier (built by Cary and based on the SLP-50 circuit) and LP-3 phono stage. I enjoyed this set-up for about 7 years. The amp was definitely on the warm side of neutral, but after comparing it to a Cary V-12i I don't think I would confuse the sound the DCA-33 produced with the classic tube sound of the Cary.
While living in CA I happened upon the designer of the DCA-33. IIRC he confirmed for me that the design was based heavily on a Nelson Pass circuit known as the A-40. It's available on the Pass DIY website.
