Threshold s150 or Forte 4a amplifier?


I have a pair of 4 ohm speakers (2 Peerless High Def 5 1/4 Mid-woofer and Vifa Ring Radiator XT Tweeter in each cabinet) that are around 89 db/ in a fairly small listening room. I have a choice of either the Threshold s150 at 75 watts/channel or the Forte 4a at 50 watts/channel Class A. I am looking for some feed back on both of these amplifiers and suggestions on which amp I should Keep. Thanks in advance for all advise!

The Threshold is in a different class, even though it's A/B. Not that the Forte is not a good amp too but, in my less than humble opinion that's a no brainer!

The Threshold in a different class? Wasn't Forte a Threshold Company? I am not sure of the relationship between the two but I know they are related in some shape or form. Can anyone fill me in?
I have not worked on any for almost 20 years, but I do not recall that much difference between them.

Actually......I like the output transistors in the Forte much better.
Yes, Forte was a Threshold company. Threshold was able to market products at a lower price point using the Forte name. I had heard the Forte 4A driving Thiel 1.5 and Martin Logan Aerius, and it was a great amp at that time for that price. Because of the power requirement of my Thiel 2.2s then, I ended up getting the Forte 6 (the 200 watt A/B version of the otherwise-the-same-design of 4A).

They share the same sound characteristics with their more expensive Threshold "cousins". Since you have both amps, why not trust your ears and make the judgment yourself?
