Thank you all so much for the advice. I never expected to get such a response from folks on here.
I appreciate each opinion, but the overall message seems clear: my issue is not with my speakers. As to the previous poster, my brother has an all Audio Research setup, and when we used his amp and the pre part of my integrated, we got pretty close to my ideal sound. As I said previously, my ideal piece of gear to go behind the Dynaudios is a Levinson 383 Integrated. I LOVE the sound of that thing. I could probably find one used on here if I wait long enough. My only concern is...at 100 wpc, and a bit more into 4 ohms, which the Dyns are...is that enough power to push my 86db speakers to loud volumes?
For the person who mentioned tube stuff, and the distinction between bloom and warmth, that's a fair point. I've listened to some good tube stuff...Conrad Johnson, Audio Research, Musical Fidelity and California Audio Labs. Right off the bat, none of the them appealed to me. Label it whatever you'd like, but I just prefer the solid state sound. I've just come to the realization that, while I love the huge amount of resolution I'm getting out of my system, its presentation is just a bit dry, a little thin, and a little bright. I'm not looking to transform the sound in my system, just to push it more towards a Levinson/Audio Research type of sound.
As for my Benchmark DAC, I'm going to stick with it for the immediate future because it's my newest component at less than two years old. It DRAMATICALLY improved the resolution in my system, though I'll admit it left my sound a bit thin and definitely trending on the bright side. Once I get into a position where I have disposable income, I'll be refining my system one component at a time.
As for my speakers, if or when I replace my Dynaudios, it's going to be with something (more) full-range. I might be willing to sacrifice a little in the way of resolution in order to get that.
Thanks again for everything!
