For me and in my system, the Lyra Atlas Lambda SL on the Primary Control FCL tonearm is the best of the bunch I tested.
That bunch included the Lyra Atlas Lambda, Phasemation PP-2000, Opus One (Airtight), the Lyra Etna, Dava Reference and Dava FC-A1
The Opus One was excellent as well, more of a sideway movement but a touch less transparent, i.e. a tiny bit more forgiving (to rest of the system).
The DAVA goes a very long way on the FCL tonearm, but the Atlas, being much lighter and having more compliance, extracts more benefits from the combination with that tonearm. The Atlas SL adds dynamic range, incredibly low, yet tight bass, even better layering, more detail but also less buttery, so more transparent to the rest of the system.
By the way, i still have both DAVA, they are in excellent condition, ready to sell them. If anyone interested, let me know!
