30 Watts of class A power: What Speakers are you using and suggesting?

I don’t want to muddy the waters with budget am asking what you are all using and I’ll use that information so make/ model works well.  

Well then. Classic Audio Loudspeakers Project T3.3  field coil drivers; no worries flat to 20Hz with dual 15" woofers. 98dB 1 watt/1 meter, 16 ohms.

I recently discovered my pass labs xa30.8 sounds amazing with 4 ohm or difficult loads. That is what I tend to stick to now.

That's because Pass (as stated by Desmond Harrington) indicates the XA30.8 will output 90 watts @ 1% into 8Ω and almost 150 watts @ 1% into 4Ω.  This is a significantly underrated amp in terms of output and can drive the heck out of a 4 ohm load.

Daedalus Argos V2s with either a Line Magnetic 518IA  integrated 845 tube based 22wpc; or Finale Audio 7189 MK2 integrated EL84M or7189a tube based 20 wpc

@three_easy_payments: That makes sense! It is easily the best amp I have ever owned. 

I am using some GPA 604 to a Luxman 590 II. It’s a good combo within the speaker limitations.

Strengths of the speakers are dynamics, efficiency and tonality. Weakness are large box size, the need for subs and not the greatest high frequency extension. I have had other speakers in the system and to this point the Altecs are still here. Mostly I love the teakwood vintage cabinets they are housed in. 

I have used tubes in the past and someday may return. But for now the Lux integrated is a good combo of sound, power and versatility.
