Threshold S300 Power Amp

I owned one briefly about 15 years ago. Unfortunately it suffered from a very wicked turn-off transient, about a minute or so after the power switch was turned off. I have no idea if that was a defect in the particular unit or characteristic of the design.

It was as if when the energy stored in its filter capacitors dissipated, the driver stages lost power before the output stages, resulting in an uncontrolled seemingly full-power bass transient. Hopefully your unit doesn't do that.

I own a S/300, partnered wit an Audio Research LS-2 pre and Apogee loudspeakers. The Apogees are demanding and revealing - and the Threshold drives them very well. I like all kinds of music, from death metal to classical. The Threshold is a musical omnivore as well.
I'd love to hear them with your Maggies, IMHO the Threshold is well suited to drive planar loudspeakers. So you have the start of a very good setup, which will give you many hours of pleasure.

I want to thank each of you and I value your great input. I am elated you would take the time to respond so quickly. Also I will investigate Audio Research and a few other pre-amps to see what works. Thank you all.

Let us know how the new amp is doing. I too am getting a s/200 and I'm curious.

Cheers!

Good afternoon everyone. The Threshold S/300 is holding up very well. I have not had a moments trouble. Also, there are no turn on or turn off thumps or other problems. So far, I am very happe with this powerful amp. Thanks all, I will be back with further details.
