threshold amp

im aware of the phase with cj 17ithe amp is clean as a whistle though the inside looks brand new Arnold at tweak audio said his tech went through it and replaced a resistor or 2.the inside is so clean it would must have been taken apart to be so clean.i believe what I need is to have a local tech examine it and tell me whats stock and whats not .maybe ill get lucky and jon solderberg can just do bias controls/circuit board caps/bridge rectifier/and main caps

oops I forgot this amp run so cool so if I get higher value caps and biased higher it should be a noticeable step up.one of my biiggest questions if anyone reading this knows is what level would that be relevant to a supposedly better threshold model. ok thanks for the many responses ...kerry

I wouldn't lose any sleep over it. Do you like the sound? If yes then just listen to it. I have a S/300. Love to have a S/500 but do I really have a need for it; no. I have a couple pairs of speakers and have no issues driving them. Now if you bought some crazy hard to drive speakers then maybe you should upgrade. At that point you would want to upgrade then have that amp rebuilt. Or as mentioned earlier just unload this one but try not to lose any money on it.

"Not true, any Threshold amp refurbished by Jon Soderberg will be worth more, however not nearly as much as the cost to refurbish. Just to make sure you know, Jon worked for Nelson Pass at Threshold as service manager. If you asked Pass, it wouldn't surprise me that he might refer you to Jon Soderberg."

You may be right. Generally speaking, modded components usually take a hit on how much they can be sold for. If this is an exception, maybe its worth doing.

"Agree, having the work done will improve the sound, but how much might be that $64,000 question. Keep in mind that any old amp will need to be serviced for reliability, and if there were any old amp I'd spend money on for service, it would be a Threshold."

Its been a long time since I heard the Threshold amps we're talking about here. I believe the Aleph's were the amps he made next, after the Threshold's. Those are pretty good even going by today's standards. They may be old, but it took a while for most of the other brands to catch up. If you can turn a Threshold into an Aleph (In terms of SQ), the mods may be a good investment.

from what I understand the alephs were built after the stasis series and the sa series which are class a like the alephs but from what I understand are considered better than the alephs. jon solderberg staes on his website that sa 50 is one of his favorites
