Tube Sound With Equalization?

Equalizer have their place - in the frequency domain - but what youre looking for isn't in there. 

@erik_squires  Ha…tried a Loki … Sent it Back within the 15 Day Window…All it did was add noise. I like to sit back and enjoy my music, the thing made me have to fiddle with it for just about every track to make it sound anything near acceptable…Basically provided fixes for problems I didn’t have !  

I recommend, from personal ongoing experience, the Jolida Foz SSX soundstage expander. It does three things, and I found the sonic costs are not too great relative to the gifts. It has a tube buffer, and that allows you to tube roll to get the best fit. It has the soundstage expander, which does as it suggests - using a knob to dial in the degree of effect. And most useful (to me) is a bass control, which I use as a “thickening agent,” to boost the bass, upper bass, and even the lower midrange. I found that I could take an underpowered solid state amp and make it perfectly acceptable by playing with this device. It also works with good amps. Worth trying.

I've heard the Jolida expander at shows and enjoyed what it does in the analog domain without causing damage.   At a much higher price point the Manley Massive Passive can make your system sound pretty much however you want it across four parallel bands.   There is a bit of a learning curve, and as Manley says in its manual, as much art as science. 

I do want to point out that Mc has a particular sound quality, it's not really about tubes.  If you liked a Mc demo in the way you are describing it may be hard to find another brand which performs the same way.   For instance, listen to a modern AR integrated and I think you'll find that sound more laid back and less detailed by comparison.
