Question about Class A

So I read all the time how awesome Class A Amps/Integrated's (SS and Tube) are.

I currently have a Vincent SV-500 Hybrid and feel it sounds really good.

But I have this itch now to hear what Class A would sound like and would it be a big difference to my current Vincent.

I wanted to ask what are some good Class A Integrated's that I could look into?

I know Pass Labs always comes up and for good reason but those might be a bit out of my budget.

I would say I can probably go to $3K new or used.

Sugden is another brand that I have researched a lot and the A21 retails for around $2500 and there is a dealer in Socal that carries it, so that one is tempting.

Vincent has the SV-237 MK II but I think that is only Class A for the 1st 10 watts into 8-ohms and I have 4-ohm speakers so I am not sure if that would give me any Class A magic. I am sure it would sound similar to my SV-500 but have more base extension.

Could you all recommend any other one's? I have been researching but haven't come across any (SS or Tube).

Thanks

Just curious: I am thinking about by-amping my speakers (Quantum 2). With low/mid, mid/high and high being the high pass from 200 Hz (200/600/4000), how much power is needed? 

The idea is to use mean brute amp for thw Watkins (dual coil, dual crossover) woofer (dipping below 2 ohm), and a class A (or tube?) for the high pass.

Does someone know the percentage (for example white or pink noise) of sound energy above 200 Hz (vs below 200 Hz)? Maybe the term is 'spectral energy'? 

Less scientific: Using 200 Watt input (rated at 350 W RMS) how much power goes to low pass ( under 200 Hz, woofer) and how much to the high pass (above 200 Hz)?
