I bought a balanced V3 cable that was supposed to be installed on an R10 by a local shop, but they were unable to do it. I asked them to install it on an L3000 instead.
The L3000 with the V3 cable has a larger soundstage, more air and better imaging than the stock L3000. It is less congested and clarity is improved.
I've been burning-in both units and will post final impressions when they've both reached 300+ hours. The comparison is made using an XLR-6.3mm plug adapter and single-ended amps.
Here's the L3000 with balanced V3 cable and Furutech XLR plugs and the stock L3000:
