Octave Filter 3-P Passive Filter System

It is almost impossible to find modern hi-fi systems lacking some level of digital signal processing today. The classic CD player has largely become obsolete, having been replaced by Internet-based sources, supplemented with hard disk storage media. This evolution means that signal connections to a network at the digital level are necessary to enable the interaction of the components.

Today's modern audio systems feature a number of digital and analog signal connections, to which a number of connections to the home's mains power are made. The modern household also features many systems and devices equipped with switching power supplies (e.g., LED lighting systems, laptop, solar panels) and radio controls (such as WLAN, etc.).

All these systems emit interference that affects nearby audio components and thus the overall sound quality of the hi-fi system.

Often an attempt is made to protect the system from interference by means of mains filters. However, this protection is very limited, as system filters work systemically only at very high frequency ranges and can in fact negatively affect the dynamics of a system. Disturbances in the important audio range are therefore unrestrictedly admitted to the audio system despite network filters and are distributed uncontrollably via the signal wiring. To eliminate the problem of propagation of conducted EMI, Octave has developed the Filter 3-P, a filtering system that acts directly in the path of interference, namely the analog signal cabling.

The Filter 3-P is a passive EMI filter system designed to be connected between any audio source component - analog or digital - and the pre- or integrated amplifier input to which it is connected. With regards to digital sources (for example with a DAC, streamer, cd-player, PC) the effect is most immediately evident. The Filter 3-P is available in two versions: fitted with single-ended RCA or balanced XLR connections. Thanks to the innovative technology implemented in this design, the same high level of noise-filtering is achieved via either of the RCA or XLR variants of the Filter 3-P.

The core of the Filter 3 is a highly specialized broadband interference suppression transformer.

The art of filter 3 was not to influence the signal, but to block interference from the bass region to the highest audio frequencies. The Frequency range of the Filter 3 spans from 10 Hz to 150 kHz / -1.5db, while the noise attenuation reaches about -80db at 1 kHz. This corresponds to a reduction of common-mode noise by a factor of 10,000. Compared with the attenuation of a line filter in this frequency range of -20 dB (corresponds to factor 10), this is a huge increase in the filter effect. (see diagram 1).

Digital-to-Analog converters particularly benefit from this measure because medium and high frequency disturbances negatively influence the sound-sensitive jitter behavior of these devices. Conversely, analog amplifiers benefit from the higher signal purity. Interference of the music signal with residual interference in the audio range is reduced, and the sound gains clarity, making even the smallest background details perfectly audible.

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.
