Our objective was to develop a 300B amplifier that provides enough power for most speakers, while not interfering with the classic 300B circuit. It was not about power for the sake of power, but about providing the 300B with a perfect environment that enhances the tonal qualities of this tube.

The concept of a 300B single-ended amplifier delivering 20-30W output power with three power tubes in indirect parallel operation was thus born.

There is a fundamental problem regarding "direct" heating of the triodes:

Unlike indirectly heated tubes (such as the KT88, KT120, etc.), directly heated triodes cannot operate directly in parallel because of the complex demands on the heating system needed increase output power.

The typical 50 Hz AC heater voltage would cause unacceptably high hum and power disturbances in the speaker. Although DC heating eliminates the hum, it also limits the sonic potential of the 300B.

Octave's solution:

We have developed a 7 Hz power generator that supplies each of the three 300B tubes with a separate, regulated 7 Hz pure sine wave heating voltage.

• This makes it possible to connect several 300B tubes in parallel.

• Sound-affecting ripple and RF disturbances of the line frequency are completely eliminated.

• Heating and operating voltage are electronically controlled, sound instabilities due the fluctuating mains voltage is a thing of the past.

• Only then can the tonal potential of the 300B be fully exploited. The 300B tubes will now operate in the optimized region and can fully develop their tonal qualities. Now it becomes clear why she is called the "queen" of tubes.

Thus, the Octave Jubilee 300 B is an absolutely modern and uncompromising implementation of arguably the finest amplification technology in the high-end sector. The amp offers an emotional, smooth, highresolution, dynamic and expansive triode sound, not only in the mid/high frequency range, but for the first time, completely across the full audio band.

Jubilee 300 B, a new generation of single ended amplifier technology without limitations.

Options:

An exciting option for the Jubilee 300 B, the bi-amping package dramatically expands the application possibilities of these brilliant mono amplifiers, as even 30 pure Class A watt amplifiers will have limits.

If you wish to enjoy the seductive sound of triodes in very large rooms or with power-hungry speakers, it is often beneficial to control the bass region by utilizing a separate power amplifier for the low frequencies. However, such traditional bi-amping requires a level of customization, thus this optional package (which is not retrofit upgradeable) includes several important features to optimally integrate the Jubilee 300B with the bass amplifier.
• The most important tool is a level adjustment to optimize the sensitivity of the Jubilee 300 B to the bass amplifier. With this controller you can perfectly integrate any amplifier into the system.
• Switchable Gain: one low and one high.

This enables one to match the amplification factor of the Jubilee 300 B amplifier to the efficiency of different loudspeakers (for speaker models over 88 dB sensitivity – gain Low, or in case the level of the Preamp and the DAC is very high). This allows the volume control of the preamp to be used in the optimum range while also further reducing noise. In principle, all loudspeakers with sensitivities as low as 82 dB and greater than 106 dB can thus be perfectly driven.
• A low-cut filter that relieves the Jubilee 300 B of frequencies below 100 Hz. Of course, all functions are switchable.
Another option for the Jubilee 300 B (also not retrofittable) is the remote function - A classic trigger that switches on the power amplifiers (with the pre-amp turned on).

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.
