Tonian speakers would be a nice fit for a 2A3. We ran the TL-D1's with a 2 watt 45 amp at THE SHOW 2011 and they were outstanding. Yes they can be a little bright but some of that comes from improper set-up, as well as what you might be feeding hem. As mentioned previously these speakers are not so forgiving. Tonian speakers work best IMO with very little if any toe in and at shows I have seen Tony rakes the front some. I have heard some of the other Tonian models as well and they get better as you move up the line.
The Audiokinesis suggestion is good one too. I have owned the Jazz Modules for a few years now and their ability to reproduce natural timbre is outstanding. They work well with my SET amps. I owned the TL-D1's simultaneously and in comparisons, while the Jazz Modules were clearly better in the lower bandwidth, and I preferred their mids as well, the TL-D1's held up very nicely against them, especially in the timbre area.
