MRE 220 SE: rock solid and yet flexible

After eleven years, and after extensive technical development projects at Octave, it was time to further adapt the MRE 220 mono power amplifiers - the rock in the surf - to the higher demands of modern loudspeakers. Long listening sessions led to the solution of an adjustable damping factor. The new MRE 220 SE damping factor can now be flexibly adjusted to ideally suit the respective speaker - resulting in rock solid reproduction quality with virtually any loudspeaker.

The MRE 120 received critical praise upon its introduction and for the 10 years it was in production. In 2004, it was replaced by the MRE 130 after a decade of experience and further development of the core MRE 120 design. The MRE 130 made improvements in detail retrieval and stability through refinements in its circuitry, most critically, in the output stage. Nearly another decade later, a major overhaul of the MRE series was undertaken based on the newly-developed KT 120 power tube. The KT 120 enabled greater power reserves and an even wider bandwidth in the MRE power amplifier output stage. Extended listening tests with a newly-developed output transformer and power supply led to the release of the MRE 220 in 2013. Its special virtues resulted in a unique combination of extremely high reliability with the utmost level of sonic finesse. The MRE 220 served as the optimal power amplifier for an unusually wide range of loudspeaker combinations. Whether employed in a bi-amp configuration with horn systems, or simply mated directly to a wide variety of high-end loudspeakers available in the global market, the MRE 220 remains a rock solid reference. Now, yet another 10 years later, Octave has taken the MRE series to another level: introducing the MRE 220 SE.

Today’s modern loudspeaker designs feature high-resolution and fidelity beyond what was achieved in the past. This, combined with the triumph of high-resolution digital formats and an extraordinary leap in vinyl playback fidelity, has led to an unprecedented quality of music playback in modern high-end systems. Despite all efforts, developing a power amplifier that harmonizes perfectly with all loudspeakers is - as experience shows – still very difficult, if nearly impossible. The requirements of the loudspeaker are too different in terms of power requirements, bandwidth and its performance, which is affected by the damping factor (and/or negative feedback) of the power amplifier.

In listening tests with many different loudspeakers during the MRE 220 SE design process, an important new tool emerged that ensures more optimal matching between our amplifier and a wider range of loudspeaker designs: an option to vary negative feedback that impacts the attenuation factor. Through use of chassis-mounted switches, the listener can choose between two damping factor settings, “LOW” or “HIGH”, along with separate settings for negative feedback. This is a completely new approach to the problem of a tube power amplifier that has to cope as well as possible with all the loudspeakers available on the market. With this unique adjustment option, the interaction of the MRE 220 SE with nearly any loudspeaker can be optimized almost perfectly. The result of this flexibility speaks for itself: an incredibly clear, spacious soundstage with a perfectly resolved and entrancing midrange that is free of any impurities, along with a silky, beautiful tonal balance.

Of course, the MRE 220 SE has power management with soft start electronics, the protection system and, like all power and integrated amplifiers, the Eco Mode, a BIAS setting and display, the power selector and a (Super) Black Box Connection.

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.
