Why are we showing the inside of it, when other company's are fearful of showing what they made.
We have no shame and we have no fear showing what we designed and made
It is not an embarrassment.
We are proud of it.

JENA technologies has made a decision about the best looking feet for our conditioner..
    After some research and a few well timed suggestions from users who know about this product, along with some experimentation...
 we have come to the conclusion that the "Strange Attractors" would work well as an option and be appropriate to complete this great power conditioner.
Normally We give a stock set of anti-vibrational rubber feet but as an option that can be purchased these look and work very well.


Strange attractors. Optional Feet - Strange Attractors is a selection we offer as selectable option.

They are fitted with 1/4-20 threaded shafts and will be fitted to inserts we include, as assembled to the completed product, if ordered.
 
If desired they can be made to order to any stable position by prior selection, the bottom, the side or to the ends of the sequoia.
selectable at the time prior to having the case made - otherwise mounted on the bottom of the case.

This link provided here best describes how these fine supports work:

Stock position is to the bottom opposite the top plate, same as the normal rubber feet we normally use.

Talk with us on ordering modification to the plans.

A snap review of one in use:

Was able to quickly listen to the Sequoia. Aptly named. Big sound.
Three immediate and undeniable impressions, one quite surprising and unanticipated. And a fourth final perhaps cumulative effect.

The first suite of effects was similar to other Jena Labs effect --> instruments and voices and ambient room around instruments and voices got bigger/more spacious.
More volume filled (like filling a balloon with air or water.) Soundstage got taller.

Second effect was most interesting --> compared to other power conditioner it was as if a "milky sluggish haze" disappeared.
Transients became clearer and sharper. More definition, especially on bass. Detail is more obvious especially in upper registers.

The third suite of effects was most surprising and unanticipated --> there was a more coherent sense of order and placement, as if without the sequoia stuff was moving about and not secure in the music plane. With the sequoia the music (instruments/voices/decay/etc) was more anchored in space and more importantly therefore more coherent in context to one another.

The final effect (maybe an outcome of other effects working together?) is the pace and rhythm was much better...speed and toe tapping and starts and stops and longer decays...the timing and pace was much much much much better ....less a speeding up of the pace and more of a removal of sluggishness if that makes sense.

The only other thing I noticed that wasn't pleasing was a bit of sharpness in the upper mids and treble ... More bite.
But this may be just more of the recording coming through and the fact the unit has less than an hour burn-in on it.

More impressions later.

Darrin's other comments and his system described:
    A customer who has purchased one of the Sequoia models.

I spent the last 5 years building out my high end audio system. It is pretty stable now and I thought I had nailed the cabling as well. I went from Cardas Golden Reference and Harmonic Technology to Audience top of the line cabling. Audience was beating anything at or below its price range and most cables that cost more, some time significantly more. I standardized on it - interconnects, phono cable, speaker cables, power cords, power conditioner. All top of the line versions. Super good stuff - read the reviews ...can't go wrong with their product. Then...I ran across JENA Labs. One modest Jena Labs Pathfinder interconnect. Wow - the soundstage was the most coherent I have heard it. No note lost; every part of the soundscape present and accounted for. Organic and natural with ZERO GLARE AND ZERO ELECTRONIC CHALKINESS OR SHEEN. Harmonics true to form.

So I have slowly been building up my system on Jena Lab cables, including interconnects, speaker cables, phono cables from tonearm, headphone cabling etc.

And...I am buying the Sequoia Power Conditioner. I have been picking up the Jena Labs Model Two power cord/conditioner. Let me say this Model Two is a taste of Jena Labs upper end impact at a really modest price. It is insanely good and incredibly reasonable in price.

I just switched out my reference 20amp power cord to my ARC Ref 2SE phono preamp. Amazing difference. The previous power cord was no slouch - beating cords 2-3x in price. The JENA Labs Model Two however took everything to a new level. The soundstage was huge - width and height. The piano and vocals and strings and high hat cymbals were oh so natural and right with perfect pitch, timing and decay. I can hear differences in power cords but usually they are modest differences and typically relate to noise floor being lowered at expense of dynamics and life and presence. Now I can hear other even more significant differences with Model Two -- the seamless and coherent and proportional sound stage, the rich natural non electronic sounding harmonics and tone. The same dramatic differences I hear with the interconnects and speaker cables are same with the Model Two to the same if not bigger degree. The first time I have witnessed that with power cords to this degree of noticeable impact.

Coherence and perfect phase/timing, absence of digital or electronic glare, natural timbre and tone with organic ease to the sound. That is the consistent pleasing musical effect of Jena Labs product. I am hooked.

Not the cheapest cables but worth every penny and then some especially the Model Two. I hope they don't raise the prices when they figure out they are not charging enough. Or if they do raise the price they need to wait until I have bought 4-5 more.

Initial impressions from another customer:

Hi Mike

Ok.. So being a true mad audio nut, was up at 0630 n started working on this mammoth task of dismantling the old conditioners and getting this Big Boy into the small space I sadly have.

Took nearly an hour and a half as had a lot rearranging to do. But finally at the cost of my back n neck had this baby connected.
Despite the system being down for those hours, the sound from the start was magnificent!

A wider soundstage. Much more defined bass and great detail ; In that order!   Yes all systems take time to resettle so I know it's only going to get better. So much to look forward to.

Once again Jen n Mike. Kudos on this magnificent product. It's definitely streets ahead. Well done guys and thank you again.

Btw now have several highly curious friends dying to come over for a listen!

Cheers/B
