heres the word from mastering engineer and serato minion wrangler –  zebulon bult .

Hi Greg,
thanks for lending me the TEN8TOR, I got excellent results out of it & I really can’t praise this EQ enough, it sounds wonderful!
Here is some feedback from my experience with it.
EKADEK GYRATOR TEN8TOR
I used the EQ in two different ways, tracking mono & stereo drum sounds/instruments. I did this from an MPC 3000, into an Apogee Duet 2.
I also recorded several stereo mixes through the TEN8TOR, I did this from an Apogee Duet 1 into an RME FF800 & also from an RME ADI 8 into a FF800.
Tracking
The results I got from tracking the drums were good. It was easy to add presence to all sounds, even if subtractive EQ’ing was necessary in some circumstances. I found it noticeably worthwhile to just track through it without gaining or reducing any particular frequency range, because it added warmth & presence. The filters sound smooth & rich but also clean & open, very musical.
Mix Bus
The mixes I was recording were coming straight out of Logic 9 & in this workflow, it really shined. It became clear to me that this EQ was nothing less than mastering grade & it had a special character. I did not use it in conjunction with my summing mixer, pultec EQ or compressor/limiter. I went straight from a stereo D/A, into the EQ, then back into the A/D. I found I was very quick in finding a no compromise mix adjustment. The TEN8TOR can add a subtle brilliance to a good mix but it also has the ability to make a rough mix sound more punchy & defined, also polished, without the obvious issue of major compromise. It’s obviously not intended to be a transparent fix your mix tool, but was surprising ly good at dealing with less than satisfactory material. The best possible scenario for this EQ is obviously a flat, well mixed track that allows you room to push it. It was a pleasure to use the TEN8TOR & I would love to have one permanently in my studio.
Pro’s:
Sections & their parameters are well spaced out with plenty of room to move.
Top quality switches and pots, large knobs that feel great to use
Thick and warm tone that is musical all the way through it’s range.
Low noise, even with hi gain, especially when you take into account that it’s unbalanced.
Total bypass and band bypass
Peak and Shelf Equalization

Con’s:  (ekadek : fair enuff that zeb didnt like some stuff. thats ok . but its my blog so i’ll chime in  if i want.) The back panel lacks rigidity when connecting & removing cable jacks.  (fixed that.one screw – thanks for pointing that out 🙂 Stepped pots for filters restrict the ability to make real time filter changes  (yes – the steps mite sound a bit odd. the special filter electronics are such fine tuned up resistor sets. u cant make a 6 gang pot that does the 6 different values and curves for under about a bazzillion $ each )  Unbalanced, more susceptible to noise.( transformer balanced is good . transformers just make it cost more) Low to Hi frequencies from right to left, this took a little while to get use too.  (fair enough – i like it that way tho –  when u turn it on its side, it becomes a perfect XXL extra huge large format console channelstrip . 4 – 8 – even 16 of these babies in a big desk. so cool and expensive. my fantastic console dream .  and it encourages/requires a different intell approach – method – style – what have you. its fresh. )

thanks zeb. the gyrator ten8tor has gotten 100% raving reviews so far. we are in love. theres just one left for sale now.  and we are  in prep  for a second limited run version two after christmas.
