Change with upgrade of Reference 3a speakers?


Planning on upgrading my Ref. 3a Veena. I am doing the basic upgrade, plus new Mundorf capacitors and the Surreal Acoustic lens upgrade.
Has anyone done similar upgrades and what were the most obvious sonic changes?

Not sure if this helps. But I had an older pair of Grand Veenas (~2008-2009?) and recently purchased a pair of GV from ~2012 with the Sureal Acoustic lens on the drivers. These were supposedly the final version before they dropped the Murata ST and went with the Be tweeter.

The differences I hear are that the newer pair will play louder without strain and have slightly more dynamic range overall.
