With the Wright amps the G2Si did not seem to live up to their efficiency specs using my little cap and coil crossover.  I can't offer good descriptions of their sound with the ML2s until I get my TT going, but there is obviously a MUCH better match now.  MUCH MUCH better, in fact.  I am very encouraged that the hardness has come up for the correct "air", which used to be somewhat hiss-y but is now properly, forcefully ragged when appropriate, and it is melded in with the sound, not just added on top.  Also, before I blame the Arum Cantus for anything I think I will try other caps in that crossover; right now I think I have a baby Auricap for that one.  All in all, I think the Arum Cantus still has plenty of "potential" for ML2, so IMO it is that "good", anyway, meaning at least it is not obviously limited with ML2.

I do not know what kind sasses you have with your Arum Cantus when you switched from Wright amps to older Lamm ML2 but I assure you that it has nothing to do with Arum Cantus. I have seen many speakers that the “vintage ML2” converted from a pile of crap into something very acceptable. The older Lamm were able to do it. I have no animosity to Wright amps, but I herd them many time and they are really kindergarten amps in comparing to older ML2. In fact the older Lamms were did not have so much worsening of sound when they drove low sensitivity tweeter as my Milq has. Lamm runs global feedback in ML2 but Melquiades has no feedback and therefore much more sensitive to load. Anyhow, if you careful chose a tube for input stage and slightly upload the output stage (use 4R tap against the high impedance load) then the vintage ML2 will give as good HF as it possible to get from a full range SET. It will not be able to play aggressively of rough if music called upon but all together it might be very much a reference how a HF should be structured by a full-range amplifier.
