Threshold S/500 (Rebuilt by Jon Soderberg Vintage Amp Repair) 250 watts per CH into 8 ohm / 500 watts per CH into 4 ohms STASIS Stereo Power Amplifier. The S-500 designed by Nelson Pass is well known for it's ability to drive difficult loads. Check out the link to reviews ( http://www.vintageamprepair.net/s500.html ) . I am impressed with the improvement in sound stage depth and upper mid range clarity after the rebuild. The highs and midrange have a tube like characteristic now. The Hex FRED rectifier possibly attributed to this change! I purchased this amp in 1986 from my local Threshold dealer to drive my new Magnepan MG 3A speakers .This S-500 has a clear cover for display , vented at the front and rear. I sent the S-500 to Vintage Amp repair in 2015 to have it totally rebuilt by Jon Soderberg ( Threshold Technician) he up graded the rectifiers to Hex FRED's. Jon also rebuilt both channels installing 40 new output transistors, 4 new 47,000 uF Capacitors , new power switch / circuit breaker ,capacitor wiring upgrade and Cardas Binding post Jon said that this amp is good for another 25 years of use. This Amp is in very good condition ! Total cost of rebuild / upgrade was $1910.25 I have since down sized to a smaller house and system . This amp today would retail for $ 10,000
