I'm having the same issues with EQ. I bought an Eich T-500 as a backup to my Tecamp puma 500. It seems less punchy than the Puma 500 too. I think I like the Puma 500 better.

Currently having both is the ideal situation that information can come from. Thanks for responding. So, even though these are said to be "transparent," I'm taking it, from what you're saying, that with the same settings (e.g., both set at noon), they sound different? Substantially so? I would think that given the basis of the differences and the things that are the same, your finding a difference "punch" would have to be entirely due to the EQ setup (baseline).
What cabinet(s) do you use? What differences are you finding in the EQ? What has your use of the taste control been?
I don't have enough time with it on stage, but the treble seems to really only control "airiness"...I don't know; maybe I can't quite articulate my meaning, but it doesn't change the substance of the overall upper range (or changes it to a lesser degree than what I'm used to), just the quality almost what I call outside of the upper margin...if that makes any sense. MB's treble shelving point is also at 10K, but it doesn't respond in the same way. This is something that clearly is going to change from cabinet to cabinet.
It may be my bass, my cabinets, my ear/preference (or a combination/compounding of all three), but the high mid seems to be at a point that just doesn't do it for me. Not sure if I'd like it lower or higher, but it doesn't seem to be where I'd like it best. The comeback has been "well, the EQ at noon is relatively flat and uncolored, so you're simply hearing what you're putting in" (i.e., telling me I don't really like the sound of my bass as much as I did). That may be true, and I could be wrong, but at noon, there is a distinct character that I believe is more than my bass is putting in. It's obviously perfect for some people but not for me.
As to the taste control. I prefer it off. Anywhere from off to noon does good things, but beyond that, it doesn't seem to add "richness" but seems to increase to depth of attenuation of upper mids and treble.
The low mid seems to be in a good spot, and the bass is just about perfect for me.
