Threshold Stasis 2...Worth a rebuild???

I have a Threshold Stasis 2 in wonderful cosmetic condition, but one channel went flooey. I contacted Jon Sondenberg and he will do a rebuild/upgrade for a little north of 1300 bux.
Jon said that the rebuild/upgrade would put the amp in the sonic category of a Pass Labs 250.

My question is, do you think it is worth sinking that kind of dough into an amp that old?

Thanks in advance to all for your wise opinions.
