Thoughts on Threshold Forte Model 3 Nelson Pass

Hi. I have an opportunity to buy a Forte Model 3, allegedly in great shape, for $350.00 including shipping. Any thoughts on this SS amp?? I'm currently using an Adcom GFA-555, which sports the same 200 wpc (I have to drive needy 4 ohm KEF Reference speakers), but I'm wondering if the Nelson Pass "pedigree" isn't worth switching for. I'm thinking I can sell the Adcom for the $350, so.... Thoughts, experts?? -David

I had an Adcom 555 and got the Forte 3.....much better sounding amp all around, IMO. Drives my 3 ohm Divas nicely. Now I have 4 Forte 3s to drive all my surround speakers.

I just bought a used Forte 3A for $450 to have as a backup amp. I was very pleasantly surprised at what a great little amp this is. Great midrange, powerful and non-fatiguing. My previous listening experience with Adcom gear was less favorable... a bit grainy, etched highs and more apt to wear down listeners during longer listening sessions. The Forte 3A is an exceptional / can't miss steal of an amp for those wanting a wonderful sounding vintage powerhouse for less than $500. Go for it!

Hey guys: Scored one for $315 on Ebay!!! The seller erroneously listed it as 100 wpc (its 200), and I think that may have kept the price down. Should arrive any day. Does anyone have a suggestion for a reasonable remote-operated preamp or preamp/tuner that will pair well with the Forte? Thanks. Also, confirmed through Threshold that Mr. Pass himself was involved in the design!! -David

Nelson Pass was at Threshold at the time of the Forte designs, but was not actually involved with the design. In fact he was opposed to the use of the IGBT transistors used. The current holders of the Threshold name, have little in common with the Threshold owners at the time the Forte line was being designed by the very capable Michael Bladelius (sp?). Don't let that bother you, the Forte amps are amongst the all time classic great value amps ever made. Enjoy!

Unsound,

The Model 3 did NOT use IGBT's like the later Forte models (after Nelson left). The Model 3 was the 200wpc AB amp of the exact same components as the 1a. The 1a was a 50wpc class A amp. And yes, Nelson had a hand in designing the early Forte models along with Rene Besne. Rene Besne was the designer of the IGBT Forte's.

You are correct Nelson didn't think IGBT's had any place being used in audio and he wrote a large paper about it which can be found on the 'net.
