Upgrade DAC or Buy New

I own a Muse 296 DAC (first manufactured in 1998) which I've always enjoyed. I just changed my system where the DAC is driving the amps directly, but the output voltage of the Muse is only 1V, so am not getting enough output. I can upgrade the Muse to their model 192 (first manufactured in 2003), but it will cost $1,200 to do so.

So the question is should I spend the $1,200 to upgrade the unit to one that has been discontinued for a few years and is a five year old model, or look for something else? I would be willing to spend up to around $2,000 or so.
