The Octave HP 700 preamplifier looks back to a long and successful history, the origins of its basic circuitry are derived from the classic HP 500 model, first presented in 1986. This concept has been consistently developed over 30 years and attracted worldwide attention.

Refined tube technology and intelligent modular technology made the HP 700 future-proof right from the start - an innovation in the market. Now it was time to push the innovative HP 700 even further in terms of sound and technology. The new HP 700 SE is a tube preamplifier that features both new precision technology and tonal refinements of the output stage. Like its predecessor, its modular freedom meets the listener's individual demand for truly customized high-end setup. Instead of being bound by the fixed audio and technical parameters of the equipment, listeners can adapt the technology of the HP 700 SE to their individual requirements and preferences.

In the new SE version, there are now two parallel XLR sockets next to the two RCA outputs on the back panel, allowing all types of bi-amping. But the modifications of the actual Class-A-output stage are even more important. The search for the even finer sound took place with the help of extremely time-consuming and complex measurements, along with accompanying listening sessions. These difficult adjustments are responsible for the tonal improvements, especially the mid-tone of the pre-amplifier. The tube configuration remains unchanged compared to the predecessor HP 700, as do all the other tried-and-tested technical refinements o this incomparable preamp:

PRECISION TECHNOLOGY IN THE LINE STAGE

The term "precision technology" stands for a circuit in tube technology that has an extreme bandwidth up to 1 MHz, an impressively low output resistance of 100 ohms and sensationally low distortion of 0.001%. Three amplification settings, combined with selectable output impedance, enable perfect fine-tuning of the HP 700 SE to the characteristics of the sound reproduction chain. The three-stage amplification settings allow optimal matching of the volume control to the efficiency of the speaker.

PSU TECHNOLOGY

In combination with the newly developed, high-precision, low-noise supply-voltage stabilizing circuitry, the separate, magnetically shielded, outboard power supply of the HP 700 SE (essential for the low-noise and low-hum function of the MC-input) ensures constancy of the audio output even when the mains voltage is subject to wide fluctuations and high interference levels. Added to this, the integrated control logic system guarantees maximum operational reliability and, backed by our exclusive soft-start technologies, ensures the tubes and the unit have a life of up to twenty years.

BYPASS

The multi-channel bypass function allows the HP 700 SE to be integrated into an existing home-theater system. The logic-controlled input selector circuitry enables activation of the bypass function for an XLR or RCA input on the preamp's rear panel. The Home Cinema signal is present at all three outputs.

ADDITIONAL INDIVIDUALIZATION OPTIONS: MODULAR INPUTS

The connection possibilities of the generously configured standard HP 700 SE model are rounded off by two user-selectable, optional input modules. An optimized input module can be used for unique applications, for anything from an MC step-up transformer to a transformer-based XLR input module. The plug and play modules can be readily installed or upgraded at any time. PHONO Innovative technology has also been applied in the redesign of the Phono RIAA amplifier. The further development of the RIAA stage has improved the signal/noise ratio, while simultaneously reducing system-related distortion. The widening of the bandwidth enables accurate RIAA equalization and exploits the full potential of analog reproduction. The wide variety of optional input modules ensures that the optimal input can be installed for any cartridge.

TONE CONTROL

PRECISON TONE CONTROL

Another innovation, the optional tone control, rounds off the HP 700 SE modularity. The valve-based, precision tone control unit guarantees consistency of the sound, even at low volume. Precise adjustment of bass and treble, with a 0.3 dB channel separation, allows the tone to be adjusted without impairing the spatial reproduction.

BALANCE CONTROL

The frequency-compensated balance control allows channel-separated volume adjustment in 1 dB steps. This technology eliminates any controller-related sound shifts. Using 12-position stepped switches, the setting is long-time stable, with 100% repeatability.

OUTPUT SELECTOR SWITCH

The HP 700 SE output can be switched to multiple zones by manual activation of the outputs. Whether the output is through XLR, RCA or all three outputs simultaneously, a total of three output stages can be utilized for separate rooms, different speakers or bi and tri-amping.

STEPPED VOLUME CONTROL

The optional, frequency-compensated, 47-position stepped switch ends the debate about the influence of the controller on the quality of the music signal. At 0.1 dB, the channel deviation is supreme. Our own in-house development, the volume control design constantly maintains the frequency bandwidth throughout the entire control range, reducing controller-related distortion to a barely measurable level. However, as a result of the mechanical design of the stepped attenuator, the switch positions cannot be controlled via the remote control.)

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.
