Blown Threshold S/300 Stasis II

David99, your right to point out the mods. I bought the Threshold gear with the mods so I can't say how much effect they had on the original sound. I do believe the modifications are fairly minor.

I own the S/300 and it's one of the finest pieces of equipment I've heard. Sure there will be better amps, but this one's a keeper.

. . . and if your old Threshold amp, S/xxx series or older, still has it's original electrolytic caps in it, you have no idea how good it will sound once you change them out with new. Be sure to change out both the large PS caps, and while you are at it, upgrade their capacity as well, and the small with some Blackgates or Rubycon ZA or ZL.

You have to figure that in these 20+ year old amps, the small electrolytics are pretty well dried out and shot, and the larger ones may still work, but are well past their prime.

The same goes for older Threshold pre-amps as well. I replaced all the small electrolytic caps with Blackgates in my SL-10. That change alone took it to a new level which now makes it a keeper, too.

I have three Threshold pieces; a Stasis 2 amp, an S/150 II, and the above mentioned SL-10. The cap upgrades to all of these Thresholds made big improvements, but the improvement to the SL-10 was over the top.
