@doyle3433 Didn't catch your response to my question, whether or not you're familiar with the Lyngdorf approach?
As I mentioned in my earlier post, I believe the TDAI 3400 has the capability to allow you to run your tube amp through it, so you can continue your torrid love affair with it. Exagerating, there. It sounds real cool.
But, seriously, I think the 3400 would give you what you're looking for in the way of "dynamic slam, and grip on the low end" in addition to allowing you to continue to enjoy the sweetness and holographic image of your Cary.
I want to encourage you to do a cursory search on what makes Lyngdorf's TDAI different. I especially recommend you read some user reviews.
I'm not a technical nerd, nor do I particularly enjoy that aspect of this hobby other than making sure I have all the right connections on my rig. But, my understanding is that this is as close as you're gonna get to, essentially, what they call a "wire with gain" setup, so that you can let the beauty of your Cary amp shine through in your presentation. I bet it would put a smile on your face.
Also not sure if you saw the response by @kennyc By the way, if you hang around and wait long enough, (probably only for a second), I think you should be able to find a (close to brand new, and well cared for) one used for five grand.
My system provides a very nice sound, and I use mine on the "neutral" setting almost always, but Lyngdorf's approach to tone controls is also quite unique. They're not true tone controls, but allow you to essentially do the same thing by shaping the curve of the sound. I can't remember the term they give it off the top of my head.
I wish you the best on your journey!
nearly spit out my coffee with laughter there my friend.
