Threshold SA/4E or Pass X-250??


Any one had a chance to spend time with these two amps? What opinions have you formed? I will be driving either Harbeth SHL5s or Harbeth 40.1s with either of them. I am mainly wondering what sonic differences i might hear? Thanks for any help.

Thanks for the info. I might hold out and try and get one of the 250.5s. The Threshold I have heard and it is something special. But it is very old, and runs very hot.

this is normal for this sort of amp - biased in pure class-A. I believe that the heatsink fins get somewhere in the 52-54C range, which is by design.
If you're still considering the Threshold, you may want to get some of the power supply parts upgraded/replaced as electrolytics age. I'm still running an old Threshold S/500 and love it.
I'm going to bring the Threshold home for an audition. I'll post my opinions compared to the Manley Snappers i have here now.
Dividebytube,
Any idea on a ballpark number the cost of replacing power supply caps?
