Suggestions for low powered tube amps for Zu Omens

Coach, I have been through the flea watt amp race for my Lascalas. As I understand it, you want this, for late night listening. As far as I am concerned, a good headphone system would be my way to go about it, as I am not willing to give up dynamics, and the lifelike " scale ", much of music listening entails. I understand many recommendations here, and respect them. It really depends on what you are looking for. As easy as your speakers are to drive, I would suggest to you to try something, with a return policy, even if you need to pay return shipping. Ultimately, none of these small tube amps do it for me ( have heard a few, not all ), but the same thing. Slow, sluggish, ill defined bass, and simply, not enough headroom, nor control, to satisfy me. Again, YMMV, but try it first, instead of making a commitment, that is all. Keep in mind, I am not speaking of only chamber music, or spls here. I also want to say, I like tubes as voltage sources, but prefer ss as current sources, which, ime, are loudspeakers. Again, my own experiences, my own opinions, and all of this is based on what " I " like ", with Lascalas, the perfect tube amp speaker. I understand I might get backlash from some posters, but, you are asking for opinions, so, these are mine. Individuality ! Enjoy ! MrD.

My Audio Research LS3 and the STA 200 really sound good together and I have you to thank for that selection.(STA -200) The only issue is gain, but there is a resistor/capacitor fix offered by Audio Research. However the 18 db of gain and 2v output might be more appropriate for a low powered amp. Another reason I'm considering a Bottlehead or Elekit or others is the ability to do double duty as a headphone amp; plus I think a kit might be a lot of fun. I believe Herb Reickert reviewed the Elekit TU8600 for Stereophile and thought highly of it. Bottlehead has the S.E.X. amplifier that might scratch the itch of kit and late night speaker experimentation.
Again thanks to everyone who responds!

The Bakoon 7511Mk3 is a wonderful sounding thing and great with high efficiency speakers.The Elekit amps are also very good but the Bakoons are really special.Only 15 watts but they have a purity to them that I have only heard from really good SET amps.

Decware. several used mini toriis for sale on the decware site. 4 watts is plenty

Coincident Dynamo 34 SE,8 wpc,high current very comfortable driving lower efficiency speakers.Average re sale on an MKII about $1,000 or less.Stellar reviews.
