Vintage Amp Repair

Specializing in Threshold/Forte Audio

 


Threshold, a Hallmark brand that made quality stereo equipment for over 20 years.  Many have said that new equipment still does not compare.

Take heart that most components can be restored to original configurations with modern parts. Browse through the  Threshold Archives to have a look at some of the products manufactured throughout the History of Threshold.  Also be sure to browse the newest web sites dedicated to the brand.  (Now I don't need to re-invent the wheel)  Look below in the links section.  There is a web site in France called Threshold Lovers.   Here you can find a pretty good history of the newer equipment made in the early 1990s.  The early history can be found on the Hi-Fi Museum web site. Many thanks to all the Threshold fans, I think the French site has the best name to describe the fan club...  Be sure to view the SA 4 re-conditioned in France.  What's not to love about this equipment!

Also, be sure to visit Audio Review, DIY Audio, and the many other sites that have reviews of these products.
I have been particularly impressed with the performance out of a modified Stasis II.  With all the right parts, this amp can hold its own against much newer and expensive units.  By replacing the power supply wire, the output transistors, installing new main capacitors, Blackgate capacitors and upgraded IXYS rectifier diodes, this amp will sound better then ever and can be reliable for 20 more years.

      Being dedicated to the experience of high quality sound I am always looking for interesting ways to demonstrate the importance of good amplification. I have always found Nelson Pass has the ability to cover all the bases in his many articles.  Power Supply  for Consumers article is highly recommended for anyone with an amplifier that weighs less than 50 lbs.

But what is the essence of good music?  and why is it important for enjoyment and good feeling?.  The audiophile experience is driven by the search for art in the music rather than the science.  For more information on the importance of good audio playback equipment please read Quality of Music at the Mark Anstendig Institute web site.  IPOD and MP3 players have there place in a busy life, but cannot award us with the same experience as listening to playback with big speakers driven by Class A amplifiers.

    Contact Vintage Amp Repair to find out more information about how your amp can be upgraded or modified.  Vintage Amp Repair offers the highest quality repair service available for your Threshold equipment.
