Update: After some listening with a single Classic 99 (awaiting delivery of the second next week), it’s evident the 99 is purpose-built for 2-channel music enthusiasts. In direct comparison to the Carbon Limited, the 99 conveyed faster transient response and greater articulation in the low end. It conveyed bass detail and nuance without masking or overwhelming the finer musical information.
Albums /tracks used in my comparison,
the bassface swing trio, duende (live), fausto mesolella (live in alcatraz), diana krall (when I look in your eyes), tron (legacy), the dark night (why so serious?), Bach Starker (suites for unaccompanied cello), Stevie Ray Vaughn (tin pan alley)
As far as placement, tried Classic 99 on carpet, but bass felt a bit soft. Placed it on a 2” Apple-Ply shelf from my Core Audio rack—huge improvement. Bass is punchier, cleaner, and integrates way better with the mains. This means, a solid wood spiked platform in walnut finish would complement and complete the finished look :-)
