The 'reclocking' done by the Benchmark and the DA10 are radically
different.  The Benchmark uses an oversampling chip, which when it
resamples at a higher frequency, maps jitter to broadband noise and
changes the bits during the process.  The reduction in jitter is very
good and is cheaply achieved, but the bits are not the same as the
source.  Other DACs use the same method with the same chip, such as the
Bel Canto, and others use much more computational power to do it even
better such as the Audio Aero.  The Lavry is a very different matter. 
Dan has many times expressed concern about oversampling and makes the
point that making chips work at higher frequencies than are necessary
just means we get worse sound because working faster means the chip
becomes less accurate (analogous to typing faster means more typos). 
Some people like the sound of upsampling and it might just be that they
like the sound of the jitter reduction achieved cheaply with a
resampling chip.

The Lavry (and a number of other high-end DACs) use what I would call
reclocking (I would call what the Benchmark does resampling, but you
could argue reclocking occurs at the same time when resampling).  The
Lavry allows the incoming stream to fill up a buffer and the Lavry then
extracts (reclocks) the data in that buffer using its own clock.  This
method of reducing jitter can be more expensive to implement for any
targeted level of jitter reduction, but it has the advantage of being
bit-perfect right up to the DAC (which the Benchmark isn't).  FWIW I
have owned but a Benchmark DAC1 and a Lavry Blue, but not a Lavry DA10.
The Lavry Blue is more expensive than the Benchmark and was clearly
superior.  But I don't know that I could put it down to jitter
differences.  I would probably put it down to Dan's skill at voicing
the sound of digital gear and the fact he had more budget to play with.
But if its true that the Lavry DA10 can match the sound of the Lavry
Blue, then it is a massive bargain.  Sell your Benchmark's now while
they still get good prices - particularly if you find the sound of the
Benchmark to be a bit thin and fatiguing.
