High Quality Distributed Audio 
When it comes to the CI 940, NAD s renowned audio performance combines seamlessly with the flexibility and reliability required for custom integration. Containing 4 channels of low distortion amplification, the CI 940 smoothly delivers the right amount of current for strong, but accurate, bass response. Designed to fit into standard rack units, the CI 940 is completely protected from both short circuit and overheating, and will automatically restore operation once a condition has been rectified. Furthermore, easy integration is guaranteed with the option of either DC trigger or signal-sensing power-on with auto shut-off. Complete with a detachable power cable for easy service and upgrades, the CI 940 provides an expansive sonic experience unique in this category of product.

The CI 940 represents NAD s newest generation of high performance amplification for custom installation and distributed audio systems. Like many award-winning NAD amplifiers before it, the CI 940 is designed by our Engineer Emeritus, Bj rn Erik Edvardsen. The CI 940 can easily provide the instantaneous peak current required for good bass response by utilizing multiple discrete high power output devices. The power supply features a custom toroidal transformer that maintains very low impedance for lowest noise and good damping factor.

Power and Performance
The CI 940 has 4 channels of clean low distortion power set up in a 2 stereo zone configuration. Boasting 35 watts of continuous power per channel, the CI 940 is designed to drive low impedance speakers and long wire runs. Vanishingly low distortion and near absence of noise allow the music to emerge from a black background that enhances stereo perspective and allows the subtle details of the music to be heard clearly. Generous dynamic power gives music a relaxed yet lively quality.

Simplicity in Integration
Easy integration is assured by the choice of DC trigger or signal-sensing auto-on with auto shut-off. The CI 940 employs a sophisticated music-sensing circuit to prevent the false triggers common with noisy source components or other types of interference noise like RF leakage or ground loops.

Rack install is made neat and efficient, since the inputs and triggers offer daisy chain outputs. The power cable is detachable for easy service or cable upgrade. The amplifier is fully protected from short circuit and overheating and automatically restores operation after the condition is rectified. Indicator LEDs for each zone show protection status.

No worries, No hassle
System reliability and ease of installation were the primary objectives in this all-new design. The 2U rack height and included rack ears make good use of precious rack space. Thermostatically controlled forced air cooling ensures a long trouble-free service life. Phoenix speaker connection blocks make installation a snap, and wiring further simplified. A bridging feature allows each pair of channels to become a single high power channel, creating additional flexibility.

Award-winning Sonics
When it comes to sound, NAD is in the top tier of all amplifier brands, consistently winning awards for both performance and value for money. Known for their warm, expansive and intensely musical sound, NAD amplifiers are designed to drive real world speaker loads, not just simple laboratory test loads. The NAD CI 940 will bring out the best performance from any speaker giving you the best possible listening experience. It is also very quiet with inaudible residual noise in no-signal conditions, important when using efficient speakers in small spaces. Energy efficiency is also impressive with <0.5W standby consumption and highly efficient power delivery. Musical, practical, efficient and reliable, the CI 940 is everything you want for high quality distributed audio.

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!

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.
