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.)

sounds great - color isn't excactly what I saw online

Easy to use; quiet operation; music quality very good for the price.

the cable is what it states it is big and heavy and flows a lot of power needed

Great streaning amp. I love that it looks like my old Yamaha CA-810 amp. However, all of the new tech and connections make the R-N2000A a more than worthy successor.

Great entry level audiophile turntable!

The Eversolo A-8 is a beautiful and very functional DAC Streamers. Aaron service was on point. All thumbs up for Safe and Sound

These are amazing speakers. I did a lot of reading reviews about these before I purchased them. And just like almost all the reviewers said, they sound incredible! The sound does bounce off the walls and immerses you with sound. Even played at low volume, The sound is just pure and realistic. I would highly recommend these to anyone who loves all kinds of music !

The speakers arrived in great condition and the sound really fills my space well. Thank you!

I was genuinely surprised by how much of an impact the Esprit Aura had coming from the Esprit Celesta. The soundstage is dramatically larger and fine details are significantly improved versus the Celesta. The bass was also significantly improved too, bringing deeper extensions on the bottom end just like the better details on the high end. The difference is so significant that’s it’s hard to give a single example because it affected everything so dramatically. As an example though, symbols taper off slower, as it preserves the softer part of the roll off that wasn’t being preserved via the Esprit Celesta cable.
My system consists of a Hifi Rose RS152 going to the RA280 integrated. Speakers are the Audel Magika Plus. Going from the streamer to the amp was a Celesta XLR interconnect.

Excellent upgrade from the 2M Red.

By far the best listening experience of any speakers I’ve owned.

I like the unit, but I have a metal roof of my house. What kind of antenna do I need? I’m having a hard time getting channels.

Great they showed up in beautiful condition, they sound great i really have been enjoying them!

Great product and flawless transaction: no muss, no fuss; arrived on time, all in good condition. What's not to like!

Great turntable, easy transaction.

Massive power, no need for a separate amp for 90 db or higher fronts. This has great streaming capability and high grade DAC.
