Symphonic Line would certainly be in the mix as well. Not a well known brand but their Kraftwerk line is definitely something to consider as well. While not cheap it is not a King’s ransom either relative to some of the astronomical prices of the top tier players.agree! their amps are really superb. Pricey but yet more affordable than dartzeel, FM Acoustics, Gryphon, Ypsilon, Lamm, etc.
I think i saw an ad for an used FM Acoustics Model 115 mono for $66,000!! wow!
