Nu-Vista PAM - Overview
Based on our excellent Nu-Vista 800 circuit we decided to go all out “fully balanced” on the Nu-Vista range.

The Nu-Vista PAM features the tried and tested Nu-Vista stage featuring 6S51N nuvistors in a discrete class A amplifier buffer.

Technical Talk
This is followed by a balanced configuration circuit and balanced input high power, low distortion “bridged” output amplifier stage. The power stages have 2x 5 pairs of high power thermally compensated output devices for reliable and stable operation.

Based on the Titan 1000W stage, it has separate capacitors for bulk supply, and one each for output device, reducing output impedance and improving dynamics. Chokes are added for further improved supply ripple and pulse current spike reduction. Bias is set for over 5W of initial class A operation thereafter the stage slides into class B operation at a point where the now much lower discontinuity is easier dealt with than “standard” crossover distortion.

Nu-Vista PAM Power Supply
The Nu-Vista PAM comes with its own dedicated external power supply.

To achieve better noise performance, we removed the AC mains power supply from the main unit and built it into another matching box. In this box we took advantage the extra space to set up inbuilt mains and output filtering. This quietens up the supplies and results in almost no mains-borne artefacts getting into the sensitive audio circuitry. The Power supply has ON/ Standby LEDs and is controlled from the main unit front panel. If total mains isolation is required, the power supply also has rear mounted mechanical rocker switch for full power off.

Heroic Build Quality
The Nu-Vista PAM‘s mechanical construction is uncompromisingly rigid and solid in typical Musical Fidelity tradition. Front panel and side panels are milled from extruded aluminum profiles and are extremely massive.

The separate Nu-Vista PAM PSU houses all the transformers, which by nature generate mechanical vibrations and radiate harmful electromagnetic fields. Here they are as far away as possible from the critical amplifier circuits. This significantly contributes to great signal to noise ratio. We basically get immunity against the effects of vibration from the environment. The same can be said about electro magnetic immunity. The massive aluminum case acts as a Faraday cage. It protects the internals against outer electromagnetic fields, and in the same way, the rest of your hi-fi gear against electromagnetic fields generated by the Nu-Vista PAM.

The Legendary Nu-Vista Stage
Never before in the history of hi-fi have Nuvistor tubes been coupled with state-of-the-art fully balanced and discrete technology and sophisticated modern design techniques. The Nu-Vista PAM & Nu-Vista PAM PSU‘s technical performances are astonishing. They measure like a dream but, more importantly, sound incredible. Silky smooth with enormous transients and an effortless feel that is at once relaxing and involving. Of special note how they project images between the loudspeakers so that you can almost touch them.

The new Nu-Vista PAM and its PSU were a continued labour of love for Musical Fidelity. We are passionate about what we do and passionate about Nuvistor tubes as we have always been. We hope that you derive as much pleasure listening to the Nu-Vista PAM as we had creating it.

Nuvistor Tubes
Nuvistor tubes were invented in the 1950s to solve the many shortcomings of conventional tubes. Unlike them, Nuvistor tubes offer very high reliability, low microphony, low noise, consistency from batch to batch, small size, relatively low power consumption and great technical performance.

One famous application was in the Ampex MR-70, a costly studio tape recorder whose entire electronics section was based on nuvistors. Another limited application of this very small tube was in studio-grade microphones from that era, the AKG/Norelco C12a, which employed the 7586, being a good example.

It was also later found in the famed Neumann U 47 studio microphone. This microphone was highly regarded by artists all over the world, and was used by many top recording artists such as Frank Sinatra, The Beatles, and so on. Remarkably, you can currently see a U47 microphone, with its stand, cables and power supply on eBay for $10.999 „Buy-it-now“.

Unfortunately just as uses for Nuvistor tubes were being explored, the transistor was invented and it was ‘game over’ for Nuvistors. There the matter rested until about fifteen years ago, when Musical Fidelity created the first of its ground-breaking Nu-Vista series. These legendary, limited-edition products sold out in a matter of months. Today, fifteen years later, they command very high secondhand prices because of their beautiful sound, build quality, and longevity.

        Great speakers For my needs. Wanted a nice full sound floor standing speaker that wasn’t harsh. Using them just for music in our fireplace room not for home theater. Not a complaint at all on their lack of lower end frequencies, I pretty much knew when I ordered them I’d be adding a sub to the mix to fill in where they leave off. Now to pick the sub 😅😂

        Fast shipping and products arrived perfectly. Thank you for a good experience

        The delivery was quick and the unit arrived earlier Then expected because I live on the west coast.
        The Eversolo T8 is everything as advertised and reviewed. The unit took about 8 hours of use to lose the bright forward sound. I’m happy with my purchase from Sate and Sound.

        I'm glad I made the choice to purchase this amplifier! I couldn't be happier and the sound is quite captivating.

        I just came back from visiting my big brother out of state who has a system in the mid 5 figure mark. When I came back I was inspired to upgrade but decided to wait. But then my Sub stopped working. I saw these on sale and thought “Is it meant to be?” Of course it was. I have these paired with a NAD T-778 streaming Qobuz. So far I am really enjoying these. I am hearing old songs as if they are new again. I have been listening to music more than ever. Bass is solid and highs are crisp. A truly immersive speaker. While I wouldn’t dare say they are as good as my big brother’s setup, they are close enough to put a smile on my face. I think they are a solid option for the price range. I am very satisfied and they are still breaking in.

        Absolute game changer! Love the device - terrific sound quality, intuitive interface and beautiful design!

        My amplifier arrived safely and has functioned wonderfully without issue. Thank you!

        Reference caliber exotic retro-futuristic LP spinner. Few rivals. Few are so flexible.

        I started years ago with an Ortofon Blue and this directly replaced a Mofi Mastertracker. I have coupled the LVB250 with a Darlington MB8 phono preamp and I can finally say that I am satisfied. This cartridge is exceptional and I don't think I'll ever need anything better.

        Really good service and extremely fast shipping. Also good price on receiver.

        Love the power of it it really feels like the gate way into high end it sounds beautiful happy with your service.Everything was all I hoped it would be thank you

        I bought the M2si integrated amplifier to drive my 2.7 magnepans. It does a very nice job of doing just that. That the amplifier is advertised as dipping gracefully or smoothly down to 2 Ohms was a primary point in the buy. Plus, Safe and Sound had a very good buy on this amplifier at $ 799.00. The build quality is very good and it has a large toroidal transformer to better handle high current and increase bass response. The preamp is full Class A and is a strong point for this Class A/B amplifier. Great buy! You can't have it all at this price though. The motorized volume knob does not have an easy viewing of where it is set as it is an inset indention without a light marker. Also, no standby power for the amp but it does have excellent heat management as the chassis has a colder side versus the hotter 2 channel amplifiers side. It is a fully discrete amplifier (wonderful, no integrated except for maybe op-amps at the preamp front). 5 year warranty, hard to beat. The amplifier has to be broken in as treble is at first very forward , but settles after a good break in period. The silver white looks very sexy and has a kind of older vibe. The M2si is British and has a brightness to it which can be toned down if you use the right speakers. Magnepans can change resistor values at the terminals or maybe even use specific DACs. No complaint about not having digital inputs at all since there are plenty of line level inputs as you can use outboards which gives you more opportunities any way. I have three different DACs into the line level inputs so all I have to do is switch out the single coax cable I want to change some of the response. I like a very well made Class A/B like this unit compared to the Class D which I have tried. Soundstage is wide and there is a lot of headroom compared to a lot of class D. If the M2si performs at 90% of what their end does like it has been said, then wow. Way to go Musical Fidelity.

        I have all Arcam equipment, the sound is fantastic. The price was amazing.. MusicLife app is so/so. Great piece of equipment..

        Safe and Sound is an excellent place to buy audio gear. This phono preamp is excellent, as sounds as advertised and the price was right!

        Amazing to deal with and best service on the planet

        So pleased with the quality as well as pretty much next day delivery. Great company

        Excellent CD player. Very impressed with the quality of the open box service. Absolutely impeccable, couldn’t tell from a brand new unit. Your customer service is also tops. Thanks for great shopping experience!

        Marantz PM7000N Integrated Stereo Amplifier with HEOS Built-in

        Amazing sound. Perfectly pairs with the components I have. Vinyl has never sounded better.

        Unit sounds great butyou can hear sound bleeding through the speakers and amp at zero volume. Also bind post so small myspade pugs either too large to accommodate. Unit turned off several times, not sure why possible connection but I could not figure out maybe due to heavy load speakers .Ssrvice and sales always fantastic!

        Super quick shipment and communications! Always great experience with Safe and Sound! The T8 is amazing! Big improvement over DMP 6!

        These outperform my previous speakers by a wide margin: more punch, more body, higher articulation. The vocals are mesmerizing.

        I was trying to scale down from a surround to a stereo setup and looking to upgrade DAC from Marantz av8805a. I have the Anthem mca 525 gen 2 amps and Sonus Faber Sonetto iii g2. It took about 70+ to burn in. It was an upgrade, but it is very subtle and hard to even notice unless really paying attention. This does fell like within the territory of diminishing returns. I don't know if it's because of my speakers, but it is the best speaker I can get given the size and weight for a small walkup apartment. However, I still decided to keep it because it is much lighter and runs cooler than the Marantz. It is also a little bit clearer (the Marantz sounded a little bit muddied, which I didn't even notice after years of using until I was comparing it with m3ai) and I noticed that it sounded louder at the same db level because of this (this means I can listen at lower db levels than I would with Marantz). I do miss the ability to fully control the Marantz via the android app. Overall a good DAC, but subtracting a little bit of points for the high price.
