...and not true lower register ability, yes. I gave up trying to get my VOTT's to do "bass" ie, 20 hz fundamentals and used them as they were meant to be used. Actively Electronically Crossed over at 80 hz 12dB/ octave and run by a 100 watt OTL amp they had as much bass control as you'd want. And even run full range by the OTL amp they did respectably well. But I'm a basshead and ALWAYS want a true subwoofer run by lots of big, highly damped SS watts in all my systems - so YMMV, etc...
I *like* the loudness button!

  I currently get plenty of bass with (Accuphase) control. SET bass tends to be slow and undefined. Perhaps amps I have used? Mid-range of course does not get any better than with SET. This is why I am considering a marriage of SET with solid state.
  
  Listen mostly to Classical, Jazz and Krautrock.

    Shindo Cortese.
    It will do it all--all by itself.
    I know,I have one(for over 3 years now).

      What speakers are you running Shindo gear on?

        I use the Solovox and of course the Cortese is a great match and really controls my massive 8 inch woofer--it should,the Solovox was voiced with the Cortese.
        I have not used the Cortese with your speakers but have used it with a few different designs including one that I was about 5 years of very familiar with at the time;thus I am fairly confident in saying that it would probably give you the closest approximation to ss bass control and SET-like,300b-like(-ish) midrange in a single stereo amp that you are going to find.
        That's why I love it.It just plays music without the typical SET limitations,as long as 10 watts is enough for the speakers.
        It is an all-rounder,not the best in any one area probably,just really damn good across the board,in all areas and just plain fun to listen to.
        Not many SETs(if any) will have the bass control of the Cortese.

    Hi MV,
    
    You state this: "SET bass tends to be slow and undefined. Perhaps amps I have used?"
    
    YES !!, almost all SET amps have problems doing bass with real life dynamics - and good ole fashioned "slam".
    
    There is an answer, and its the ONLY one I am aware of.
    
    Build an SET amp with a ultra powerful and "fast" power supply, and you will have almost ALL the life and dynamics that was recorded in the original event. I know of NO other good way to reproduce this. It is an AMPLIFIER design problem, and not a speaker problem.
    
    One very low powered SET amp, on a A-7 moded speaker, can and should "do it all". I know how to build them. A few others have done so also. Contact me off-Forum and I can provide details.
    
    Amps, not necessarily speakers, are the biggest audio TURKEYS of all !!
    
    If you biamp, there are problems : you have an extra active stage (crossover) which ROBS your transparency, and unless both amps are identical, you will HEAR the time constant anomalies, or mis-timing, and differing signatures, between differing amps, on ANY real good high resolution system.
    
    The best answer is to build a GREAT SET amp! It is actually possible to do so, now a days. How refreshing.

      Agreed, I've periodically been a 'broken record' that it's the typical SET amp's weak/narrow BW power supply that's the culprit, but when folks price out the components required any discussion grinds to an abrupt halt.
