Tube vs Solid State

Folks,

For past few months, I have been trying to achieve best possible sound in my rig. The focus now is clearly on a improving 2 channel sound in what started as a home theater room.  

In past couple of years, I have added N10, Modwright DAC and very recently a LS36.5 linestage . The amps are Modwright KWA150SE. I am running pair of KWA150SE's in bridge mode (450Wx1) for the mighty B&W 800D2's.  While I like the sound as is, still feel something is missing. 

I have been toying with the idea of bi-amping.  One thought is to add mono tube amps to run mid's and high's and let the KWA150SE's handle the LF's. I am pursuing that seductive, slightly warm mid-range and top end that usually comes from tube amplification.  

I don't think there is any tube amp out there by itself capable of powering up bass hungry 800's. I prefer not to use a subwoofer in 2 channel setup. I listen to mostly jazz and classical music and quite sure that 800's are capable of producing adequate bass with proper amplification. 

Any feedback would be appreciated. 

Cheers!

Would this be a good time to add those Zero autoformers that Ralph advocates?
Maybe.

What I was thinking is that hard to drive speakers are hard to drive. As the many posts in this thread are pointing out.

Amps of any persuasion don't like working hard- they invariably make more distortion which is easy to hear as it tends to be higher ordered harmonics (which the ear uses as loudness cues). This is part of why balancing the lows and highs can be so tricky, since the ear converts distortion into tonality, and the distortion is not an actual frequency response issue! So you wind up trying to adjust for a perceived frequency response issue which that's not actually the problem.

So you might consider switching to a speaker that is easier to drive- they are out there and can make just as much bandwidth and detail as you experience now but without the driving headaches (which often lead to real headaches).
