Threshold SA/1

Hi,
So I inherited a pair from my father who has used them for the last 20 years. Cosmetically in great condition, but one unit was unfortunately shipped upside down and one of the caps leaked. Last recap was early 2000s and they need to be voltage changed to 120v since they are from Europe. So they need to be recapped and fully serviced.

The options from what I can tell are sending them to Threshold in Texas, to Soderberg in CA or a qualified repair shop in the mid Atlantic. I live in DC. Cost quoted by Threshold and S. about 2k plus shipping both ways (200lb).
I am worried about the shipping as they are irreplaceable and I had UPS damage amps before.
- Are there any good repair shops in the mid Atlantic?
- If they have to be shipped - Soderberg or Threshold?
- Does anybody have experience with the amps. Which parts should be upgraded?

From what I read these are classics, Pass’s Stasis design, class A and look great with the analog meters.I remember they sounded good in the past, but would certainly like to hear them with my system.

Opinions?

Thanks for all the feedback on the shipping. I suspect the amps will have to go on a pallet, but even LTL is damaging and losing goods frequently in our company. I suspect you package as good as possible and roll the dice.

When talking to Threshold they say that the amp will be brought back to factory settings. Vintage amp from what have been reading has done unknown modifications to increase performance. Has anybody experience with modding the equipment vs factory refresh? I read about larger caps etc.

FWIW, I have been led to believe that the original designer of your Threshold’s, Nelson Pass has endorsed his former Threshold employee Jan Soderberg’s work.

Your choice is between the company that will insure that they produce as close to original sonics as possible and the man who will insure that they produce the best sonics possible. 

I know what my choice would be: Soderberg all the way. Have a Stasis 2 that he updated in 2003; transistors, resistors, hexfred diodes, power supply and circuit capacitors. The improvement in sound quality, primarily inner detail, smoothness, lower noise floor and frequency extension were startling. 

You really can't lose either way...except for that gnawing feeling of 'How much better could they have sounded if I'd sent them to Soderberg?'
