THRESHOLD 4000 RARE VINTAGE CUSTOM SERIES POWER AMPLIFIER
This is an extremely RARE Threshold and has the Custom Series LOGO on the Front of the Power Amplifier. Most of these used Threshold 4000 used amps in average scratched-up condition sell between $1,700 - $3,900 each !!!
After speaking with both Threshold and Pass Labs (lead technicians) here is the story on this amplifier.
It is an early Threshold 4000 with a Threshold 400 non-illuminated face-plate that was sold to a manufacturer in the high-end audio industry as part of their product development cycle for their end product. That is why it does not have the standard production markings on the back or front of the amp. See Pictures of the inside and it is a 4000 model as seen with large Mallory Electrolytic Capacitors (4 of them).
This Threshold 4000 has a very clean faceplate and nice contrasting attractive silver rack handles and is in good cosmetic condition. Also, it sounds very powerful, effortless and is extremely smooth with tons of headroom. The sonic signature is pure, relaxed, sweet, tube-like across the full frequency spectrum. The inner detailing is very impressive as well. It is a non-fatiguing listening experience.
More on the Threshold 4000 Power Amplifier:
Threshold 4000 power amplifiers were one of those over the top, lunatic fringe power amplifiers created by the legendary audio amplifier engineer Nelson Pass. The Threshold 4000 literally stood the audio world on its proverbial ear when it was released. For once here was an amplifier that produced 200W x 200W RMS into 8 ohms in Class A output. Totally unheard of for the time and remains to this day one of audios all time cutting edge designs. The promise of high-end was finally realized in the early products from Threshold and the 4000 was the flagship amplifier from that era and still retains in flagship status today.
Few amplifiers today can compete with the 4000 at any level. To find one today is one of audios great finds, seems that audiophiles that have them, keep them. Now that speaks volumes about the enduring legend of the Threshold 4000. These early Threshold amps were and remain lifetime products.
The build and craftsmanship of Threshold is legendary and not many other manufacturers can even come close to this level of quality today. No matter what was thrown at the Threshold 4000, it plays music with a verve that until that time had not been heard. Without question this was the beginning of high-end audio as we now know it.
