Threshold SA/4e and SA/2

Mywing · 20th December 2009, 08:49 PM

Has someone compared these two amps?
SA/4 is for me the best choice but... what sonic differences with SA/2 monoblocks? Is changing an upgrade or a downgrade?

Cheers

It's been so many years that I can't remember. They
are pretty similar, though.

Well, I listened a SA/4e many years ago and I loved it so much.
Now at last I've found one, but once I've found a pair of sa/2 almost half the price of the SA/4e. Unfortunately I haven't the opportunity to listen them...
But if their sound and their characteristics are equal to SA/4e the problem is already solved!
Another thing: how do the two units to be very similar if between them there are about ten years apart.
Thanks for the clarifications

I didn't say equal. I said similar.

They are different in details, mostly front end, and of course
the SA2's are monoblocks.

My SA2s are wonderful. I don't think you can go wrong with a pair of Sa2s or SA1s. These were and are still fantastic music movers.

Can the Sa/2s operate at both 220V than 110V?

Oh no. The amps must be converted to either 110V or 220V. Not switchable.

Thanks.
What is the procedure to convert them? Does it is very difficult to do?

For converting the SA/2s contact either:
Jon Soderberg <vintageamp@comcast.net>
or
Threshold Audio, Inc. <support@thresholdaudio.com>

Either will provide you a price (should be around $500 for the conversion only).
I would also state the age of the AMPS as they probably need some upgrading and/or overhauling. If you have them overhauled (recommended), it may cost between $750 and $1,200 and that price may include the conversion (good deal).
I strongly suggest having the upgrade done as it brings the AMPS to at least the original spec.
But contact either POC and they will take good care of your SA/2s.
Good Luck.
