Never before in the history of hi-fi have NuVistor tubes been coupled with state-of-the-art SMD technology and sophisticated modern design techniques. The technical performance of the Nu-Vista 800.2 is astonishing.
- Over 300 watts per channel with unconditional stability margins and incredible load-driving capability.
- Incredibly low distortion over a colossal bandwidth.
- Extremely low noise.
- Extremely flat frequency response.
The Nu-Vista 800.2 offers dreamlike measurements but, more importantly, it delivers incredible sound. It is silky smooth with enormous transients and an effortless feel that is both relaxing and captivating.
Of particular note is how the Nu-Vista 800.2 projects images between the speakers so that you can almost touch them.
The TITAN Heritage The Nu-Vista 800 was an amplifier that enjoyed great popularity and extensive use as a high-end hybrid integrated over the past few years. It was originally designed in 2013 to revive the then-discontinued Nu-vista family of products.
We reworked the old Nu-Vista circuit according to modern practices, and it was the first to include the locally decoupled output stage since the TITAN. This involved giving each output device a corresponding high-current storage capacitor. These capacitors, mounted on the power amplifier PCB, give it a similar appearance to that of a “V10” engine!
Mounting such a capacitor near each output transistor allows more immediate access to stored energy, with a much lower impedance path for the flow. This results in better transient response and, coincidentally, provides a degree of improved ripple filtration at higher currents in conjunction with the storage capacitors located elsewhere.
The main storage capacitors are located right on the rectifiers, also reducing the power supply impedance and helping to keep rectification noise and hum away from the high-gain PA circuit.
This unit was very popular, bringing the Nu-Vista sound to a new generation of listeners, and a matching CD player was also produced, receiving great acclaim.
From Nu-Vista 800 to 800.2 Unfortunately, as is the case with everything encompassing modern as well as more traditional technology, certain parts were discontinued. The original “retro look” display was suddenly no longer produced, with very little notice. We were thus faced with a choice: discontinue a popular amplifier or find a workaround and replace the original with an updated version, while staying as unchanged as possible from the original formula.
The Nu-Vista 800.2 received a modernized front plate and a completely new display. It aligns with our new range of Nu-Vista products. We quickly realized that we would need to update the power supply circuits and the electronic on/off control to accommodate the new display. Fortunately, this meant that we could also add the missing remote on/standby function.
And while we were at it, we had our transformers rewound for lower standing flux, making them less sensitive to mains DC offset noise. This resulted in a slightly larger (and heavier) transformer which, fortunately, still fits the same casing.
The result is that we now have a new hybrid integrated amplifier, the Nu-Vista 800.2, which will visually fit into the new range of Nu-Vista products while keeping the audio parameters of the original intact, and even improving them in some areas.
