So far, I'm loving it! I almost went with a much cheaper version with 9 bands, but at some point, you're just turning knobs with no real objective. This had definitely enhanced my Hifiman Edition XS from "Really Good" to "Majestically Awesome"! Not all ears are the same, and tweaking is good for a lot of people. And for a lot of speakers/headphones. I like the solidness of it, and though it doesn't "match" my Schiit amp, it "goes" with it.

Good EQ that can be bypassed by powering off the unit.It contains 15 swappable opamps. I am not certain, but I think they are the Ti NE5532p dual opamps.Not certain. I didn't take a deep dive. Just enough to look inside to see the opamps. You know how Ti has the state of Texas stamped on their opamps. Well, that is what I seen. Maybe could be swapped out with Burson 5Vi dual discrete opamps, and/or Sparkos SS3602 dual discrete opamps.It has good build quality. I'll evaluate the T7 in my audio rig for a time to see if it is worth upgrading the opamps. Just glad I have that option. F.Y.I It appears to be worth the $99 (US) asking price.Update: Real nice addition to my rig. I would definitely buy again. Still contemplating rather to upgrade the op-amps. The unit sounds great on it's own. No noticeable noise or artifacts. It's a keeper.I also would like to add that all the frequency adjustment knobs have a balance notch that lets you know when they are in the balanced position. They adjust -/+ 6db. It really doesn't matter that you can't tell precisely where you have it set. You should only adjust the frequencies that need it, and then you adjust it till it sounds the way you want. I have all my frequencies set to the balanced position 98%-99% of the time.

This unit elevated my current TT and amp set up.I have an Audio Technica 120 TT and a Yamaha AS301. The 301 does a good job on its own but I wanted to add warmth to my vinyl. This unit deliver just that. I’ve been able to adjust the sound to my liking and it truly provides me with the warmth I was looking for! Paired with my Wharfedale speakers, things sound really good.

When I was purchasing this I couldn't find much in way of visuals on this just the actual measurements.I'm super impressed with the build on this thing! And it does exactly as advertised. Fortunately it fit in a little space I needed it to fit into, and weirdly it was the only thing I could find in the internet to do this little job. So these guys don't have any competition in this area.I only have limited EQ on the gadgets on the desk there. So being able to get another stage of EQ on the output headed toward the house PA is an amazing fix. Cuz I don't typically have access to the house PA so now I have the ability to make the necessary adjustments for audio comfort and feedback suppression etc.If you got a job and it looks like this thing will do, not only is it the only one out there available to do this little kind of a job, but it's a high quality piece of gear, especially at that price point.
