Older PURE CLASS-A Amplifiers

The older Threshold S and SA series amps can still hold their own against the newer equipment. I am quite familiar with them and have heard many of them over the years at a local dealer that used to sell Threshold. I currently have the S350e Class A/AB model. As someone else had mentioned, I think I would shy away from the T-50 model because I also have heard that the IGBT ouput devices used by the T series are no longer available. All of the older Threshold amps that I have heard, including my own have delivered a relatively neutral presentation, depending on what other components were also in the chain. IMO they have a similar sound to the Pass X series amps. If you happen to see one of the class A SA series for sale GRAB IT!

Don't forget about the Sugden A21ap, excellent 25wpc pure Class A. They show up here occassionally for well under $1,000.

Threshold SA/1's & SA/2's set the standard in Pure Class A sound.

I own a Threshold T200 and I would not consider selling it. Poweful beyond its 100W/channel rating and still one of the sweetest sounding SS amps I've heard. Put a pair of MIT Oracle Cables on it or Transparent Ultras or Refs and you will stop searching for power Nirvana.

Elinor: You should try your Threshold with some Goertz MI-2 Veracity cabling. Just make sure to use proper impedance compensation i.e. Zobel networks and see what you think. The results are extremely complimentary and natural sounding for a staggeringly low price. Sean
